Few weeks ago, someone asked me “What are the top 10 formulas?” That got me thinking.
While each of us have our own list of favorite, most frequently used formulas, there is no standard list of top 10 formulas for everyone. So, today let me attempt that.
If you want to become a data or business analyst then you must develop good understanding of Excel formulas & become fluent in them.
A good analyst should be familiar with below 10 formulas to begin with.
1. SUMIFS Formula
If you listen very carefully, you can hear thousands of managers around the world screaming… “How many x we did in region A, product B, customer type C in month M?” right now.
To answer this question without the song and dance of excessive filtering & selecting, you must learn SUMIFS formula.
This magical formula can sum up a set of values that meet several conditions.
The syntax of SUMIFS is like this:
=SUMIFS( what you want to sumup, condition column 1, condition, condition column 2, condition….)
Example:
=SUMIFS(sales, regions, “A”, products, “B”, customer types, “C”, month, “M”)

2. X/VLOOKUP Formula
Pop quiz time ….
Which of the below things would bring world to a grinding halt?
A. Stop digging earth for more oil
B. Let US jump off the fiscal cliff or hit debt ceiling
C. Suddenly VLOOKUP (or XLOOKUP) formula stops working in all computers, world-wide, forever
If you answered A or B, then its high time you removed your head from sand and saw the world.
The answer is C (Well, if all coffee machines in the world unite & miraculously malfunction that would make a mayhem. But thankfully that option is not there)
XLOOKUP or VLOOKUP formula lets you search for a value in a table and return a corresponding value. For example you can ask What is the name of the customer with ID=C00023 or How much is the product price for product code =p0089 and VLOOKUP would give you the answers.
The syntax for VLOOKUP is simple.
=VLOOKUP(what you want to lookup, table, column from which you want the output, is your table sorted? )
Example:
=VLOOKUP(“C00023”, customers, 2, false)
Lookup customer ID C00023 in the first column of customers table and return the value from 2nd column. Assume that customers table is not sorted.

3. Dynamic Array Functions
Excel 365 introduced a new class of functions called DYNAMIC ARRAY FUNCTIONS. These will let you filter, sort, extract distinct values from your data with ease. It also added a special formula functionality called spill behavior. It means Excel formulas can now return multiple values as a result & spill them down as needed. See this quick GIF demo.
Learn more about the POWERFUL dynamic array functionality in Excel (video).
4. IF & IFS Formulas
Q: What do you call a business that does not make a single decision?
A: Government!
Jokes aside, every business needs to make decisions, even governments!!! So, how do we model these decisions in Excel.
Using IF formulas of course.
For example, lets say your company decides to give 10% pay hike to all people reading Chandoo.org & 5% hike to rest. Now, how would you express this in Excel?
Simple, we write =IF(employee reads Chandoo.org, “10% hike”, “5% hike”)
The syntax of IF formula is simple:
=IF (condition to test, output for TRUE, output for FALSE)
10 must know Advanced IF formulas.
5. Nesting Formulas
Unfortunately, businesses do not make simple decisions. They always complicate things. I mean, have you ever read income tax rules?!? Your head starts spinning by the time you reach 2nd paragraph.
To model such complex decisions & situations, you need to nest formulas.
Nesting refers to including one formula with in another formula.
An example situation: Give 12% hike to employees who read Chandoo.org at least 3 days a week, Give 10% hike to those who read Chandoo.org at least once a week, for the rest give 5% hike.
Excel Formula: =IF(number of times employee reads chandoo.org in a week >=3, “12% hike”, IF( number of times employee reads chandoo.org in a week >0, “10% hike”, “5% hike”))
You see what we did above? We used IF formula inside another IF formula. This is nothing but nesting.
You can nest any formula inside another formula almost any number of times.
Nesting formulas helps us express complex business logic & rules with ease. As an analyst, you must learn the art of nesting.
Lots of nested formula examples & explanations here.
6. Basic Arithmetic Expressions
=(((123+456)*(789+987)) > ((123-456)/(789-987)))^3 & " time I saw a tiger"
If you read the above expression and not had to scratch your head once, then you are on way to become an awesome analyst.
Most people jump in to Excel formulas without first learning various basic operators & expressions. Fortunately, learning these requires very little time. Most of us have gone thru basic arithmetic & expressions in school. Here is a summary if you were caught napping in Math 101.
| Operator | What it does | Example |
|---|---|---|
| + – * / | Basic arithmetic operators. Perform addition, subtraction, multiplication & division | 2+3, 7-2, 9*12, 108/3, 2+3*4-2 |
| ^ | Power of opetator. Raises something to the power of other value. | 2^3, 9^0.5, PI()^2, EXP(1)^0.5 |
| ( ) | To define precedence in calculations. Anything included in paranthesis is calcuated first. | (2+3)*(4+5) calcuates 2+3 first, then 4+5 and multiplies both results. |
| & | To combine 2 text values | “You are ” & “awesome” returns “You are awesome” |
| % | To divide with 100. | 2/4% will give 50 as result. Note: (2/4)% will give 0.5% as result. |
| : | Used to specify ranges | A1:B20 refers to the range from cell A1 to B20 |
| $ | To lock a reference column or row or both | $A$1 refers to cell A1 all the time. $A1 refers to column A, relative row based on where you use it. For more refer to absolute vs. relative references in Excel. |
| [ ] | Used to structurally refer to columns in table | ourSales[month] refers to the month column in the ourSales table. Works only in Excel 2007 or above. Know more about Excel Tables. |
| @ | Used to structurally refer to current row values in a table | ourSales[@month] refers to current row’s month value in oursales table. |
| # | Spill Operator (Excel 365) | Used to get spill range from a dynamic array formula |
| { } | To specify an inline array of values | {1,2,3,4,5} – refers to a the list of values 1,2,3,4,5 |
| < > <= >= | Comparison operators. Output will always be boolean – ie TRUE or FALSE. | 2>3 will be FALSE. 99<101 will be TRUE. |
| = <> | Equality operators. Check whether 2 values are equal or not equal. Output will TRUE or FALSE | 2=2, “hello”=”hello”, 4<>5 will all return TRUE. |
| * ? | Used as wild cards in certain formulas like COUNTIFS etc. | COUNTIFS(A1:A10, “a*”) counts the values in range A1:A10 starting with a. For more on this refer to COUNTIFS & SUMIFS in Excel |
| SPACE | Intersection operator. Returns the range at intersection of 2 ranges | A1:C4 B2:D5 refers to the intersection or range A1:C4 and B2:D5 and returns B2:C4. Caution: The output will be an array, so you must use it in another formula which takes arrays, like SUM, COUNT etc. |
7. Text formulas
While there are more than two dozen text formulas in Excel including the mysterious BHATTEXT (which is used to convert numbers to Thai Bhats, apparently designed by Excel team so that they could order Thai take out food #), you do not need to learn all of them. By learning few very useful TEXT formulas, you can save a ton of time when cleaning data or extracting portions from mountains of text.
As an aspiring analyst, at-least acquaint your self with below formulas:
- LEFT, RIGHT & MID – to extract portions of text from left, right & middle.
- TRIM – to remove un-necessary spaces from beginning, middle & end of a text.
- SUBSTITUTE – to replace portions of text with something else.
- LEN – to calculate the length of a text
- TEXT – to convert a value to TEXT formatting
- FIND – to find whether something is present in a text, if so at what position
Here are my top 6 TEXT formulas for data analysis.
8. NETWORKDAYS & WORKDAY Formulas
“There aren’t enough days in the weekend” – Somebody
Whether a weekend has enough days or not, as working analyst, you must cope with the working day calculations. For example, if a project takes 180 working days to complete and starts on 16th of January 2013, how would you find the end date?
Thankfully, we do not have to invent a formula for this. Excel has something exactly for this. WORKDAY formula takes a start date & working days and tells you what the end date would be.
Like wise NETWORKDAYS formula tells us how many working days are there between any 2 given dates.
Both these formulas accept a list of additional holidays to consider as well.
- NETWORKDAYS: calculate the number of working days between 2 dates (assuming Saturday, Sunday weekend)
- NETWORKDAYS.INTL: Same as NETWORKDAYS, but lets you use custom weekends [Excel 2010+ only]
- WORKDAY: Calculate the end date from a start date & number of working days
- WORKDAY.INTL: Same as WORKDAY, but lets you use custom weekends. [Excel 2010+ only]
More on working with Date & Time values in Excel.
9. SMALL & LARGE Formulas
Almost nobody asks about “Who was the second person to climb Mt. Everest, or walk on moon or finish 100 mtrs race the fastest?”.
And yet, all businesses ask questions like “Who is our 2nd most valuable customer?, third vendor from bottom on invoice delinquency? 4th famous coffee shop in Jamaica?”
So as analysts our job is to answer these questions with out wasting too much time. That is where SMALL, LARGE formulas come in handy.
- SMALL: Used to find nth smallest value from a list. Use it like =SMALL(range of values, n).
- LARGE: Used to find nth largest value from a list.
- MIN: Gives the minimum value of a list.
- MAX: Gives the maximum value of a list.
- RANK: Finds the rank of a value in a list. Use it like =RANK(value, in this list, order)
10. IFERROR Formula
Errors, lousy canteen food & dysfunctional coffee machines are eternal truths of corporate life. While you can always brown bag your lunch & bring a flask of finely brewed coffee to work, there is no escaping when your VLOOKUP #N/As. Or is there?
Well, you can always use the lovely IFERROR formula to handle errors in your formulas.
Syntax:
IFERROR(formula, what to do in case of error)
Use it like:
IFERROR(VLOOKUP(….), “Value not found!”)
Click here to learn more about IFERROR Formula.
3 Bonus Formulas
If you can master the above 10 formulas, you will be ahead of 80% of all Excel analysts. Here are 3 more important formulas that can come handy when doing some serious data analysis work.
- OFFSET formula: to generate dynamic ranges from a starting point and use them elsewhere (in charts, formulas etc.).
- SUMPRODUCT formula: Unleash the full power of Excel array processing by using SUMPRODUCT.
- SUBTOTAL formula: Calculate totals, counts & averages etc. on a range with filters.

=NOT(STDEV(A1:A4))
this also works for large ranges of numerical values (but not for text)
@Arie
Nice formula Arie
Except that it doesn't work for Text values
I'll submit
=COUNTIF(A1:A4,A1)=COUNTA(A1:A4)
which works for Numbers and Text
and answers the two bonus questions as well
This is waaay more elegant than my solution. Nice one :).
I had =NOT(COUNTIF(A1:A4,A1:A4)-COUNTA(A1:A4)), somehow I keep forgetting we can use more than one "=" sign on a given formula :-/
Hi
Works for numbers, text and logical values on a range from A1:An.
=COUNTIF(A1:An,A1)=ROWS(A1:An)
well if you name the range, you could use following:
=IF(SUMPRODUCT(1/COUNTIF('range','range'))=1,1,0)
Hello lockdalf
The IF()-part is not necessary.
=SUMPRODUCT(1/COUNTIF(‘range’,'range’))=1
Not Working for =IF(SUM($C$1:$F$1)=0,"",SUM($C$1:$F$1)) in cell A1 to A4
My solution is a, perhaphs slightly complex, array formula as follows:
{=IFERROR(AVERAGE(IF(ISBLANK(A1:H1),9999,SUBSTITUTE(A1:H1,A1,9999)*1))=9999,FALSE)}
Assuming there is a value (numerical, text, logic etc) in cell A1, this formula will work - and it will 'ignore' any cells that are 'blank' within the range A1:H1 (which can be extended to the required size).
Breaking the formula down, the SUBSTITUTE(A1:H1,A1,9999) replaces all values (be it text / numerical) in the range A1:H1 that MATCH the value of cell A1 with the number 9999 (this should be changed to any number that WON'T APPEAR IN THE RANGE).
These values are then multiplied by 1 (as SUBSTITUTE results in a text answer).
Wrapping this in an IF(ISBLANK(A1:H1),9999,.........) formula takes care of any blank cells, setting them to this default value of 9999 also - this allows you to set the formula up once for a large range and then not have to alter as more data comes in.
An Average is then taken of all these values - if all cells that contain values are the same, the average will come back to 9999.
If all values are numerical but some differ, the average will differ from 9999 and will result in a FALSE answer. If some / all of the values are text and some differ from that in cell A1, the AVERAGE function will result in an Error, but in these instances the Match needs to return FALSE, hence the IFERROR function.
Sure there's a simpler way to do this though!!
`{=IF(AND(COUNTA(RANGE)-SUM(--ISNUMBER(FIND(UPPER(FIRST ELEMENT IN RANGE),UPPER(RANGE))))=0,LEN(FIRST ELEMENT IN RANGE)=MAX(LEN(RANGE))),TRUE,FALSE)}`
so if your data was in Column 1 and began in A1, you'd use
`{=IF(AND(COUNTA($1:$1)-SUM(--ISNUMBER(FIND(UPPER($A$1),UPPER($1:$1))))=0,LEN($A$1)=MAX(LEN($1:$1))),TRUE,FALSE)}`
This will work for strings and things, if you want it to be case sensitive (I don't), just remove the UPPER() part.
What this does:
`COUNTA($1:$1)`
tells you how many entries you're looking at over your range (so we can work with an undetermined size).
`--ISNUMBER()`
ISNUMBER will return TRUE or FALSE depending on if the value inside is a number or not. the -- part converts TRUE/FALSE in to 1 or 0.
`UPPER()` OPTIONAL
converts the value in to upper case. If passed a number it changes it to text format. This is what stops it from being case sensitive.
`FIND($A$1,$1:$1)`
will return a number if A1 is contained in each cell containing an entry in column 1.
`LEN($A$1)=MAX(LEN($1:$1)`
checks that all elements are the same length. This is needed to avoid partial matches (without it, if A1 contained zzz and A2 contained azzza it would flag as true).
REMEMBER this is an array formula, so enter with ctrl+shift+enter.
{=MIN(--(A1=OFFSET(A1,,,COUNTA(A1:A4))))}
Gives 0 if false and 1 if true
=COUNTIF(A:A,A1)/COUNTA(A:A) = 1
This meets both bonus requirements and is dynamic. Keep adding more contents in column A and it will include these automatically.
I like this a one a lot. I would make one small change by inserting a table for my data range. Makes it dynamic without selecting the whole column
=IF(COUNTIF(tableName[colName],A2)/COUNTA(tableName[colName])=1,TRUE,FALSE)
For only Numeric values
=MAX(A:A)=MIN(A:A)
Awesome!
=(A1=B1)*(B1=C1)*(C1=D1)
Case sensitive.
=SUMPRODUCT(0+EXACT(A1:A4,A1))=COUNTA(A1:A4)
Regards
I'd use this
=COUNTIF(range,INDEX(range,MODE(MATCH(range,range,0))))=COUNTA(range)
It takes Hui's formula but ensures that the test value for the countif is the value or string that is most common in the range. Just in case you get a false but the problem is just with your test value being the odd one out.
=SE(E(A1=A2;A1=A3);SE(E(A1=A4;A2=A3);SE(E(A2=A4;A3=A4);"ok")))
SE = IF
E = AND
Seems you could shorten it with
=AND(A1=A2,A1=A3,A1=A4)
Bonus question 1 & 2
Array formula: {AND(A1=A1:AN)}
This will test all cells in range, including text and numbers.
Cheers
A very simple solution uses Excel's Rank function. Insert in B1 = Rank(A1, $A$1:$A$4). Copy down this formula to B4. If the answers in B1 thru B4 are all 1, the values are equal. For an open range of cells, label the range of input (example "TestData") and place the label in the funtion (= Rank(A1, TestData) then copy down to an equivelent length of rows as the range.
=IF(SUM(A1:A4)/COUNT(A1:A4)=A1,TRUE,FALSE)
=IF(SUM(A1:D1)/4=A1,"True","False")
I enjoy your emails. I have learned a lot from them. Thank you for what you do.
.
{=PRODUCT(--(A1=A1:A4))}
.
Change A4 to An.
Greate
{=PRODUCT(- -(A1=A1:A4))}
=IF((SUM(A1:A4)/COUNT(A1:A4))=A1,"TRUE","FALSE")
I would use the formula which is mentioned below:-
=IF(PRODUCT($A:$A)=A1^(COUNTIF($A:$A,A1)),"Yes","No")
At last a homework assignment that I could answer on my own. And I even understand some of the elegant answers from other readers this time.
My solution was to nest IF statements:
=IF(A4=A3,IF(A3=A2,IF(A2=A1,TRUE,FALSE),FALSE),FALSE)
This satisfies bonus question 2 but I think the structure makes it impossible to modify this solution to satisfy bonus question 1. And I wouldn't want to use this strategy to compare very many values...
This answers all of your questions:
=PRODUCT(--(INDIRECT("$A$1:$A$"&$B$1)=$A$1))
where column A contains the values and $B$1 has the number of rows to assign to last A-cell.
Sorry, forgot the braces:
{=PRODUCT(–(INDIRECT(“$A$1:$A$”&$B$1)=$A$1))}
=IF(A1=A2:A2=A3:A3=A4>1,"TRUE","FALSE")
=IF(A1=A2:A2=A3:A3=An>1,"TRUE","FALSE")
=SUM(HELLO, A1)
{=IF(SUM(IF(A1:A4=A1,0,1))=0,TRUE,FALSE)}
This will work for numbers or text, and will work for any number of cells (A4 would just be An)
Here's another alternate, assuming values in cells a1:d1
=IF((A1*B1*C1*D1)^(1/COUNT(A1:D1))=AVERAGE(A1:D1),1,0)
{=IF(AND($A$1:$A$4=OFFSET(A1,0,0)),1,0)}
=SUM(IF(FREQUENCY(MATCH(A1:A4,A1:A4,0),MATCH(A1:A4,A1:A4,0))>0,1))
REVISED FORMULA
=IF((A1=A2)*AND(A1=A3)*AND(A1=A4),"TRUE","FALSE")
Regards
=IF(SUMPRODUCT(--(A2:A5=A2))/COUNTA(A2:A5)=1,1,0)
- should be --
I would use something like this: =COUNTA(A1:A4)=COUNTIF(A1:A4,A1)
You can even do a whole range and as you enter data into the range it tells you if they all match. Going down to row 5000: =COUNTA(A1:A5000)=COUNTIF(A1:A5000,A1).
Thanks,
B
Just saw Hui response. I really did come up with this and didn't just copy his.
{=SUM(--(A1:A101=A1))=(COUNTA(A1:A10)+COUNTBLANK(A1:A10))}
For numeric values:
=(OFFSET(list,,,1,1)=AVERAGE(list))
where list = A1:A4
I need to retract my own post here guys.
It is WRONG! Let me explain.
Suppose we have
A1 = 1
A2 = 0
A3 = 2
then Average = 1 and OFFSET(list,,,1,1) = 1
so 1 = 1 but all the elements are NOT equal.
correction
{=SUM(--(A1:A10=A1))=(COUNTA(A1:A10)+COUNTBLANK(A1:A10))}
=IF(A1=B1,IF(B1=C1,IF(C1=D1,TRUE,FALSE),FALSE),FALSE) ....
=COUNTIF(OFFSET($A$1,0,0,COUNTA($A:$A),1),$A$1)=ROWS(OFFSET($A$1,0,0,COUNTA($A:$A),1))
I have a little more flexible approach. Suppose the value of 'n' is known. There is a possibility that only some of the cells in a row are filled up. For example if n = 10, then in a row, A1 to A10 must be compared. But in case only cells upto A7 are filled up. The formula thus has to adapt accordingly. Below formula does that:
=COUNTIF(INDIRECT(ADDRESS(ROW(),1)&":"&ADDRESS(ROW(),COUNTA(A1:J1))),A1)=COUNTA(INDIRECT(ADDRESS(ROW(),1)&":"&ADDRESS(ROW(),COUNTA(A1:J1))))
In A1:A100 is word/number
In B1 is word/number we look
C1=MAX(FREQUENCY(IF(A1:A100=B1,ROW(A1:A100)),IF(A1:A100<>B1,ROW(A1:A100)))) array formula
We can use an array formula
{=PRODUCT(--(A1:An=A1))}
OR if we want n variable
{=PRODUCT(--(INDIRECT("A1:A"&COUNTA(A:A))=A1))}
Just as an add on...
The range could be 2D as well
{=PRODUCT(–(A1:Zn=A1))}
{=AND(A1=A2:An)}
I would use this one (simlpe)
=(COUNTA(A:A)=COUNTIF(A:A;A1))
try this
=MAX(A1:A4)=MIN(A1:A4)
Olso try this
{=SUM(RANK(A1:A10,A1:A10))=COUNT(A1:A10)}
Please notice it is an Array Formula
Dear All,
i used that formula
{=IF(COUNTIF(A1:A4,A1:A4)=COUNTA(A1:A4),TRUE,FALSE)}
Love the variety of responses.
=MAX(A1:A4)=MIN(A1:A4)
and
=COUNTA(A1:A4)=COUNTIF(A1:A4,A1)
will return true if the input range has blank cells
My personal fave is the array formula {=AND(A1=A1:A4)}. Short and sweet, and easy to read. Blank cells will tally as a mismatch.
A close second is
=SUMPRODUCT(1/COUNTIF(A1:A4,A1:A4))=1
which will throw an error if blanks are present.
=PRODUCT(B1:D1)=B1^COUNT(B1:D1)...will return TRUE or FALSE
Dear Sir,
My answer is =exact(a2,a1)
=IF((a1=a2=a3=a4),1,0)
4 equal values gives me a 0 ???
Hello Chandoo,
We can also use Conditional Formatting......
For Numerics..
=SUM(A1:AN)/A1=COUNT(A1:AN)
results in True/False.
=AND(IF(A1=B1,1,0),IF(B1=C1,1,0),IF(C1=D1,1,0))
=AND(A1=A2:A4) array entered
Generic
=AND(A1=A2:An) array entered
=--(COUNTIF(A1:A4,A1)=COUNTA(A1:A4))
will give value as 1 or 0
Hi there, here's a simple formula to determine not only whether all 4 cells (A1 --> A4) are equal, but also whether any of the cells are equal and identifies which cells they are ...
=COUNTIF($A$1:$A$4,A$1)*1000+COUNTIF($A$1:$A$4,A$2)*100+COUNTIF($A$1:$A$4,A$3)*10+COUNTIF($A$1:$A$4,A$4)*1
A result of 1111 means no cells are equal, 4444 means all cells are equal, 1212 would mean there are 2 cells the same & they are in A2 & A4, etc
=((A1=B1)+(A1=C1)+(A1=D1))=3
Obviously doesn't cover bonus question 1, but does so for q2 🙂
If formula
=MIN(A1:A4)=MAX(A1:A4)
Try this formula
=IF(COUNTIF(A1:A4,A1)-ROWS(A1:A4)=0,"True","Flase")
I used the Swiss knife of excel: SUMPRODUCT, works for numeric as well as for non-numeric cell content and A1:A4 is obviously easily changed to any range.
=IF(SUMPRODUCT(--(OFFSET($A$1:$A$4,0,0,ROWS($A$1:$A$4)-1,1)=OFFSET($A$1:$A$4,1,0,ROWS($A$1:$A$4)-1,1)))=ROWS($A$1:$A$4)-1,TRUE(),FALSE())
All of the individual non-array formulas (didn't test the array ones) have one flaw or another - mostly specifically if all the columns are blank, the result would still be false.
Another formula in the comments worked for these but didn't work for when all columns had "0.00" in them. My solution was to OR the two. If H3 through H149 have your values, then this is what worked for me:
=IF(OR(COUNTIF(H3:H149,H3)=COUNTA(H3:H149),SUMIFS(H3:H149,H3:H149,1)=COUNT(H3:H149)),IF(H3="","Blank",H3),"")
This solution puts "Blank" if all the rows are blank, otherwise, it puts whatever the value that's in all of the rows - "0.00" or whatever.
Thanks for all the answers!
I used a nested if statement which also showed, via the false message, the first instance of cells which were not equal for the cells a1 to a5.
=IF(A1=A2, IF(A2=A3, IF(A3=A4, IF(A4 = A5, "True","False A4"), "False A3"), "False A2"))
Hi,
First, let me begin by saying, I am a big fan of all your posts and read your emails, mostly on the same day as you send them. I have not replied as much as I wanted to.
This is my first attempt at answering a question on your post
I came up with a simple check which will test if all values in a range A1:An are same or not
Assuming range you want to check is A1:A10,
In Cell B1, insert the formula
=IF(COUNTIFS(A1:A10,A1)=COUNTA(A1:A10),"All cells are same","All cells are not same")
The idea I applied is counting total number of non-blank cells and then counting the number of cells which match cell A1. If these are same, then it means
a) all cells have the same value! (All can be blank, then both counts will be zero)
I am working on finding the range automatically 🙂
Can extend this into VBA and use InputBox etc to generate some user interaction
Thanks
Shailesh
=IF(COUNTIF(A1:A4,A1)=COUNT(A1:A4),TRUE,FALSE)
For homework & Bonus Question 3
=IF(AND(A1=A2,A2=A3,A3=A4),1,0)
=IF(SUMIFS(A12:A15,A12:A15,1)=COUNT(A12:A15),1,0)
One possible solution could be =+IF(COUNTIF(A1:A4,A1)-COUNT(A1:A4)=0,1,0)
where A1:A4 is data range which can be a dynamic range and the formula can be modified accordingly.
Rgds,
Sanjeev Sawal
I got the right result with this one:
=IF(A1=B1;IF(C1=D1;IF(B1=C1;1;0);0);0)
=and(a1=a2,a1=a2,a1=a3)
ANSWER FOR bONUS 1
=MAX(A1:A10)-MIN(A1:A10)
=AND(A1:A3=A2:A4)..Confirm with Ctrl+Shift+Enter (As as array formula). Works well for Text values and large range of values as well.
suppose cells contain 2 values ==== Yes | no
formula :
1
=counta(a1:a4)=countif(a1:a4,"yes")
It will return True or False.
2
=IF((COUNTA(A1:A4)=COUNTIF(A1:A4,"yes")),"Same value","Mis-match")
it will return Same Value OR Mis-match.
Hope you like it.

Also can use this formula
=IF(AND(A1=A2,A1=A3,A1=A4),"1","0")
Let say the values are in the range $B$1:$E$1, then the formula is:
If(sumproduct(--($B$1:$E$1=$B$1))=CountA($B$1:$E$1);1;0)
Please check that:
* $B$1 was used as pivot value and could be randomly selected
* It works well if parenthesis is omitted for values "1" and "0"
* This formula applies also to "n-values" and non-numeric values (text, logical, etc.)

This formula is equivalent to
If(CountIF($B$1:$E$1,$B$1)=CountA($B$1:$E$1),1,0) mentioned before...
Hi, first time trying to solve a probleme.
New at this but really enjoying Chardoo.org
Think the following will work in all 3 questions
{=IF(SUM(IF(A1=$A:$A,1,0))=COUNTA($A:$A),TRUE,FALSE)}

use below formula for to get True / False
=COUNTA(A1:A4)=COUNT(A1:A4)
and use below formula for to get {1/0} or {match / Mismatch}
=IF(COUNTA(A1:A4)=COUNT(A1:A4),{1,0} or {match,Mismatch})
=IF(COUNTA(A1:A4)=COUNT(A1:A4),1,0) or =IF(COUNTA(A1:A4)=COUNT(A1:A4),"Match","Mismatch")
[...] Last week in Write a formula to check few cells have same value [Homework], [...]
Hi, sorry if it's repeated, this array formula works well with numbers or text, the range can easily be dynamic: {=AND(A1:An=A1)} Now, after three days, I understand a lot more about array formulae, thanks?
=IF(AND(A1=A2,A2=A3,A3=A4),"TRUE","FALSE")
What if there are not only four cells to compare but An?
how will I determine if there is one cell that is not equal from any other cells?
=IF(COUNTA(A1:A4)=COUNT(A1:A4),1,0)
=IF(COUNTA(A1:A4)=COUNT(A1:A4),”Match”,”Mismatch”)+
=IF(AND(A1=A2,A2=A3,A3=A4),”TRUE”,”FALSE”)
=iF(AND(EXACT(C15,D15),EXACT(E15,F15)),"Match","Mis-match")
how this formula works in excel (B4+E4)/50*20
I'm a little late to the party, but I figured I'd post anyways.
For numbers only:
=NOT(VAR.P(A1:An))
The formula given below will fulfill the all criteria including bonus questions
=IF(COUNTA(A:A)=COUNTIF(A:A,A1),"True","False")
REGARDS
=IF(MATCH(A1,A2:A4,0),TRUE,FALSE)
=IF(COUNTIF($A$1:$A$4,A1)>1,"true","false")
=IF(COUNTIF(A:A,A1)>1,"true","false")
@Naveen
You can simplify your formulas as below:
=COUNTIF($A$1:$A$4,A1)>1
=COUNTIF(A:A,A1)>1
Excel will return True or False without the need for the If() function
Hi ,
This question is similar to the one in the post.
I have Text values in cell A1 and A2.
If A1 = A2, update 10 in cell A3 , else 0.
Is there any formula for this. I am new to VB and hence do not have much knowledge. Eager to learn!!
Thanks in advance !!!
=AND(A1=A2,A1=A3,A1=A4)
also =IF(AND(A1:A4=A1),TRUE,FALSE)
my question is
finding the total of values in cell A1,A2,A3,A4,andA5
@Norine
Is it as simple as =Sum(A1:A5)
One can use "IF, AND" formula.
=IF(AND(A1=A2,A2=A3,A3=A1),"True","False")
=COUNTIF(A:A,A1)=COUNTA(A:A)
Enter array formula like, = IF($B$16:$B$21=$B$17:$B$22,"Yes","No")
Sorry, Enter a array formula like this: =IF(AND($B$16:$B$21=$B$17:$B$22),"Yes","No")
=IF(AND($E$5=$E$6,$E$6=$E$7,$E$7=$E$8),"true","flase")
it can work try this one
A question for you
sheet 1 table A1:C10
What formula in sheet 2 A1 will give me what is entered in the table sheet 1 A1:C10
There is usually only one entry made in the table but if you can supply the answer to 1 or 2 entries I would be grateful
=max(A:A)=min(A:A)
FOR TEXT DATA
=COUNTIF(A1:A5,a1)=COUNTIF(A1:A5,"*?")
FOR VALUE DATA
=COUNTIF(A1:A5,A1)=COUNTA(A1:A5)
Both Return TRUE or FALSE
=if({sum(1/countif($A$1:$A$n,A1:An)}=1,"All Same","Not All Same")
I use formula A1=B1 and get value of TRUE / FALSE in C1. I had dragged this formula for 10 rows. Now in cell D2 i tried to put formula..
=if(and(c1="False", c2="true"), "conflict", "no conflict")
but even when the condition is true i am still getting no conflict.
Can you please advice?
thanks,
Manish
@Manish
Remove the " from around True and False
=if(and(c1=False, c2=True), "conflict", "no conflict")
In C1 and C2 you have a Boolean expression and it evaluates as True/False
These are not text, although they do appear as Text, they are not 1/0 although they sometimes behave as 1/0, they are in fact Boolean values True/False
So in your example you can simplify it as
=If( And( Not(C1), C2), "conflict", "no conflict")
=SUMPRODUCT(MATCH(A1:A4,A1:A4,0))=COUNTIF(A1:A4,A1)
Answer to both bonus questions 2 and 3:
=COUNTIF(A1:An,A1)=COUNT(A1:An)
answer to all questions:
={IF(ISERROR(MATCH(FALSE,((A1:An)=$A$1),0)),"same","different")}
this works with numeric, non-numeric, and blanks:
COUNT will not count numeric
COUNTA will count blanks as one
=SUMPRODUCT(1/COUNTIF(B1:J1,B1:J1))
This will tell you how many unique values exist in the selected range. Text or numeric mixed.
{=IF(AND(A1:A9=A2:A10),"EQUAL","NOT EQUAL")}
this is an array formula, insert it with CSE.
COUNTA/UNIQUE
=SUMPRODUCT(A:A)/A1=COUNT(A:A)
=COUNTIF(A1:A4,A1) = COUNTA(A1:A4)
