The other day, while I was putting my kids to sleep, this idea came to me. How do I check if a cell contains a palindrome, using Excel formulas?
Next morning, I wrestled with excel for about 20 minutes and boom, the formula is ready.
Here is how it works:
If you enter a word or phrase in column B, it would tell you whether it is a palindrome or not.
But what is a palindrome?
A palindrome is a word, phrase, verse, or sentence that reads the same backward or forward. For example: A man, a plan, a canal, Panama!
[definition from palindromelist.net]
So, to check if a cell contains palindrome, we need to reverse the cell contents and see if both original and reverse are the same.
For example if B1 contains MAN, then the reverse would be NAM and hence MAN is not a palindrome.
But how do we write a formula to check if a cell has palindrome?
- Assuming B1 contains the word (or phrase), the first step is to clean it. That means, we need to remove any spaces, commas, exclamation marks & other punctuation symbols. So a phrase like “Cigar? Toss it in a can. It is so tragic.” would become “CigarTossitinacanItissotragic”.
- The next step is to match this cleaned text (lets say this will be C1) with the reverse of it.
- But there is no reverse formula. So we use MID() to extract one letter at a time and match it with the corresponding letter from end. (ie first letter with last letter, second letter with second last letter etc.)
- To do this, we use,
MID(C1,ROW(OFFSET($A$1,,,LEN(C1))),1=MID(C1,LEN(C1)-ROW(OFFSET($A$1,,,LEN(C1)))+1,1) - The left portion of this formula would give individual letters in C1 in left to right order and the right portion would give same in reverse order.
- We wrap this in a lovely SUMPRODUCT formula so that we can check for palindrome-ness of B1 using
=IF( SUMPRODUCT( ( MID(C1,ROW(OFFSET($A$1,,,LEN(C1))),1) = MID(C1,LEN(C1)-ROW(OFFSET($A$1,,,LEN(C1)))+1,1)) + 0 ) = LEN(C1), "It’s a Palindrome", "Nah!")
How does this formula work?
Well, that is your weekend homework. Go figure.
One more homework if you are game
If you feel like playing with words, here is another challenge.
How would you test if a cell contains alliteration?
(Alliteration here is defined as sentence where all words begin with same letter)

Its possible to display up to 4 text values.
Have a look at the screen shot of an example that I had posted way back at the EHA and figure out how its done !

With Excel 2010 you can use Conditional Formatting to apply custom number formats which can display text. (In older versions you can only modify text color and cell background color, but not number formats.) Using CF allows for an even larger number of different display values.

Hey,
Thanks, this helps. But how do you do it for multiple values where there is a huge amount of non repeating text?
@Soumya
The only way to do more than 4 values is to make the Pivot Table manually with formulas, of course then it isn't a Pivot table
You can of course do it with VBA
You may want to have a look at this description of how to do it here: http://www.clearlyandsimply.com/clearly_and_simply/2011/06/emulate-excel-pivot-tables-with-texts-in-the-value-area-using-vba.html

[...] Pivot Tables take tables of data and allow the user to summarise and consolidate the data at the same time. This is a great and very fast method of analysis but is restricted to handling mathematical functions on the value field resulting in numerical summaries. – read more [...]

There is a very good way actually for handling text inside values area.
First you create a special column on the very left side and call it ID, and put unique ID (numbers only), and then create a pivot table with:
Row Labels and Column labels as you like, and in the Values labels use the unique ID number.
Move the unique ID number (copy paste) somewhere to the right and use vlookup to load the data you need using the ID as reference.
It is a bit longer way but for me it works perfectly to combine values as you like in any moment.
hope helps.

Thank you! I finally understand pivot tables thanks to your clear, concise explanations and examples.
Good Day. This is exactly what i have been looking for. However when i try it on my pivot table or even when i try to recreate this exercise using the sample worksheet, i get this error:
"Microsoft Excel cannot use the number format you typed. Try using one of the built-in number formats."
Same thing here, Excel quite did not like the format in my PowerPivot. Any clues as to what may be going on? Thanks.
I have the same thing happening on my end. I'm running a normal pivot table on a .xlsm file.
@Danzi
What format did you use?
can you post the file ?
pls. help in table there is name, pan. amount. i have to make pivot table for example
NAME PAN AMOUNT
MR.X AAAAC1254T 500.00
MR.Y AAABR1258C
MR.A CFVDE2458T
MR.Z AAVCR12548C
MR.X AAAAC1254T
MR.Z AADCD245T
pls. help in table there is name, pan. amount. i have to make pivot table for example
NAME PAN AMOUNT
MR.X AAAAC1254T 500.00
MR.Y AAABR1258C 1000
MR.A CFVDE2458T 2000
MR.Z AAVCR12548C 5451
MR.X AAAAC1254T 45564
MR.Z AADCD245T 4500
how to get pivot tabe so i get PAN no. against Name.
I found an easy way to get text values in pivot table.
I create an other worksheet in wich each cell has a formula that copy the pivot table. The trick is that the formula does a lookup for the numbers in the pivot table.
The formula looks like that:
=IF(ISNUMBER(table!A1);VLOOKUP(table!A1;Code!$A$1:$B$65;2);IF(ISBLANK(table!A1);" ";table!A1))
Code is a worksheet where there is a liste of text /numbers correspondance.
As a bonus The new sheet is easier to format
Additional trick:
In my case, i encoded differents codeid with a power(2, codeId-1) so that summing then is equivalent to concatenate them.
1-A
2-B
4-C
8-D
yields :
5 - AC
14 - BCD
Hi
I want to ask if pivot can display dates in pivot field. As in a column i have customers and in row different items i want to know there last purchase date. anyone help in this??
Hello Guys, Need your help
I am doing some analysis of the cycle time of the product i.e how much time a product takes from manufacturing to the central warehouse.
I have batch numbers for the product and against them i have to pull out the diff. dates
Like the base date is from where the manufacturing start. So i have the batch number,against it's manuf. date. Now i have to pull out the date when it was quality released.
I have the quality released data but the data have duplicates, like i will have two dates or may be three for the same batch. So my main objective is to pull out the date which is latest among them.
BATCH NO. DATE of Mfg. DATE of Quality release
A1 12/4/2014 (HERE I HAVE TO PULL value)
Next Sheet
BATCH NO. DATE of Quality Release
A1 14/5/2014
a2 23/5/2016
A1 12/5/2014
A1 13/6/2014
From this sheet i have to pull up the latest date format of date here is dd/mm/yyy
TIA
