Billy – do you want to send me your document and I’ll see if I can figure it out in a few minutes?

Hi Michelle

Sadly it’s still happening. I have changed the values to reflect my cells (A1 – A210) but when I press enter I still get the same error. It also seems to want to change the word “no” in “no duplicate”.

Billy — try this —-

=IF(MAX(COUNTIF(A1:A11,A1:A11))>1,”Duplicate”,”No Duplicate”)

Also, be sure that the A1:A11 is changed to reflect the actual range you are comparing duplicates for.

Hi there

I am using this formula for work, however when I cut and paste your formula my excel tells me the formula I have typed contains an error. When I click okay it then highlights the word “duplicate” within the formula. Any ideas? If I can’t figure this out I am going to have to ctrl + f for EVERY piece of data in my very enormous spreadsheet!

Thanks for any help

Kristina – yeah I always love to hear that my Excel videos saved people time! I’m so glad we re-connected through LinkedIn as a result of a guest blog post on Olinda Services website!

Marsha – I’m a really visual person. Without seeing the spreadsheet it’s hard for me to know what the issue may be with your formula.

As usual you are the MASTER! You have no (or you probably do) idea how much time you just saved me each day!

Hello,
I am working on a spreadsheet and have combined the values of 2 cells into one.

using formula: =(MID(I4,SEARCH(“[",I4)+1,SEARCH("]“,I4)-SEARCH(“[“,I4)-1))&”;”&H4

However, I need to know how to keep H4 from being added if that value already exists in I4.

Can you please help?
Thank you,
Marsha

Carissa:
It is awesome isn’t it! I have so many reasons why I love Filters – they also come in really handy when trying to pull “select” data out of specific areas — especially when you have a spreadsheet that has a lot of info in it. For example: I work with a spreadsheet handling monthly water and sewer charges for a 220+ apartment building complex. Every month I need to make sure there are no errors (meaning units that may have not gotten a digital reading). The best way for me to accomplish that is to use the Filters and then only review data that is blank (or zeros). So many fun uses for Excel.

Thanks again for being the inspiration behind this post! Now I’m down 2 of my 3 posts for the week….this ROCKS!
