Excel exclude list of values from all areas of workbook

JohnD,

I'm assuming your questions have two parts..

1. If you want to see whether values of C2:C50 exists in cells B2:B350 then use this formula in D2 and drag it down...

=Countif(B$2:B$350,C2)

Select allOpen in new window

Now drag this down till D50 and for any values which exist it will give you 1 or how many times it exists if it doesn't exist it will give you a zero as answer...

2. Assuming you don't have any blank values from B2 to B350..You can use this formula at any cell it will tell you whether it has duplicates or all values are unique..

=IF(COUNTA(B2:B350)<>SUMPRODUCT(1/COUNTIF(B2:B350,B2:B350)),"Has Duplicates","Unique")

Select allOpen in new window

Saurabh...

I posed my question poorly; my apologies

I want to make sure the values in Column B are unique throughout the workbook. Is there a formula which I can place in Column C which checks for each value in Column B across the whole workbook?

Which are the columns or range you want to check for duplicate???

Assuming if you want to check columns D TO E then you can use..

=countif(D:E,B2)

This formula need to be applied in C2..Now if the count is more that means this value exists more then once IN Column D and E.. You can play around with this formula as in range and drag this down to check how many times values exists..

Saurabh...

Thank you; I have 8 tables on 8 separate worksheets which need to be checked for duplicates

That works! Thank you!

You are welcome..Always happy to help.. :-)
