Today, lets learn OFFSET formula.
What is OFFSET and why bother using it?
OFFSET formula gives us reference to a range, from a given starting point with given height and width in cells.
OFFSET formula syntax
OFFSET formula looks like this:
=OFFSET(starting point, rows to move, columns to move, height, width)
- Starting point: This is a cell or range from which you want to offset
- Rows & columns to move: How many rows & columns you want to move the starting point. Both of these can be positive, negative or zero. More on this below.
- Height & width: This is the size of range you want to return. For ex. 4,3 would give you a range with 4 cells tall & 3 cells wide.
And yes, All the arguments to OFFSET can be references to other cells. That means, you can write =OFFSET(A1,D1,D2,D3,D4) which will refer to a range
- Starting from A1
- Offset by D1 rows & D2 columns
- having the size of D3 rows & D4 columns
See below examples to understand the formula better.
OFFSET formula examples
Why use OFFSET?
Why not write a reference like A1:C4 directly?
Here are a few reasons why,
- Dynamic ranges: Reference like A1:C4 always refers to the range A1:C4. ie it is static. But sometimes, we want our ranges to be dynamic. This is required because our data is changing (every month new row is added, every time we launch a product new column is added etc.)
- We don’t know the exact address: Sometimes, we don’t know what our ranges actual address is. Rather, we just know it is starting from a certain cell etc. In such situations OFFSET is useful.
Understand OFFSET formula – Interactive Workbook
Since OFFSET formula is somewhat tricky to get, I created an interactive workbook so that you can understand how it works. When you input all the 5 parameters, the workbook highlights the range that your OFFSET will give. After playing with it for a few minutes, you will understand the formula better.
Practical use for OFFSET – Average of latest week
Lets say we monitor quality of a plant producing purple puppets. One of the KPIs we monitor is % of rejected puppets. We have been tracking the % of rejects by day in a spreadsheet that looks like this:
So how do we calculate average of latest week?
Assuming the values are in range C3:C18, we can write =AVERAGE(C12:C18)
BUT, WE NEED TO CHANGE THIS FORMULA EVERYDAY!!!
Even puppets would find that boring.
By using the OFFSET awesome sauce, we can write the AVERAGE formula once and forget about it.
=AVERAGE(OFFSET(C3,COUNTA(C3:C300)-7,0,7,1))
Lets break-apart this formula and understand
- To calculate latest week’s average, we need to go all the to the last data point and then get 7 rows from it and average those values.
- This is where COUNTA(C3:C300) – 7 comes in to picture. It counts how many values are there in column C and then subtracts 7 from it.
- The OFFSET would then starting point from C3 to latest week’s starting point.
- To know how this formula works, watch below demo.
OFFSET limitations
While offset formula can return with a dynamic range when you beckon, it does have few limitations:
- OFFSET formula is volatile: In plain English it means, whenever there is any change in your workbook, OFFSET formula is recalculated, thus keeping Excel busy a tiny bit longer. This is not an issue if you use OFFSET formula in a small workbook. But when you use lots of OFFSET formulas in large workbooks, you will end up cursing Excel as it takes too much time to recalculate.
- OFFSET formulas are tricky to debug: Because the references are dynamic, debugging a workbook with lots of OFFSETs can get tricky quickly.
Alternatives to OFFSET formula
There 2 fine alternatives to OFFSET formula.
- Use Excel Tables: Since Excel 2007, we can create tables from structured data and write formulas, create charts that refer to dynamic ranges with ease. Click here to know more about tables.
- Use INDEX formula: Although not exactly same as OFFSET, INDEX formula can also be used to generate dynamic range references. Plus, INDEX is a non-volatile formula, so it wont keep Excel busy unnecessarily. Know more about INDEX formula.
Do you use OFFSET formula?
For most of my dynamic range needs, I rely on tables or INDEX formula. I use OFFSET formula when I have to calculate values like average of latest week. In such cases OFFSET is an elegant solution.
What about you? Do you use OFFSET formula? In which situations do you use it? Please share your tips & examples with us using comments.

=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.
Regards
Istiyak
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$1 was used as pivot value and could be randomly selected
* It works well if parenthesis is omitted for values "1" and "0"
* This formula applies also to "n-values" and non-numeric values (text, logical, etc.)
Regards,
A
This formula is equivalent to
If(CountIF($B$1:$E$1,$B$1)=CountA($B$1:$E$1),1,0) mentioned before...
Hi, first time trying to solve a probleme.

Jorrie
use below formula for to get True / False
=COUNTA(A1:A4)=COUNT(A1:A4)

@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:
