# Excel/comparing 2 sets of numbers to find same

Question
Hi Tom

I have 2 columns of products codes, one is the product codes i current use and one is a master list containing all the product codes and updated pricing.

I need a formula that will search the master list and find the numbers that match my list so i don't have to search thousands of lines of information to find the ones that only i need to act upon

Happy to send an example if needed

Thank
Marcus

Marcus,

Say your master list is in column A of sheet1 and your other list is in column A of sheet2

in column B of Sheet2 you could do this

Sheet2, B2:  =countif(Sheet1!\$A:\$A,A2)

then drag fill down column B

this will indicate which items in the second list are found in master.

Or you could go the other way.

Sheet1, B2:  =countif(Sheet2!\$A:\$A,\$A2)

(this could be any column in sheet1 if column B is already occupied)
then drag fill down the column.

the cells containing a number other than zero are the ones that match.  If the number is greater than 1, then you have duplicate entries.

If you wnat to find what row in the other sheet you could use

=match(\$A2,Sheet1!\$A:\$A,0)
use that in Sheet2  or in Sheet1
=match(\$A2,Sheet2!\$A:\$A,0)

If I wanted to pull back the value in say Column C of the matching row I could use

=Index(Sheet1!\$C:\$C,match(\$A2,Sheet1!\$A:\$A,0),1)

match will return a #N/A error if no match is made.  If you have Excel 2007 or later you could do

=IfError(Index(Sheet1!\$C:\$C,match(\$A2,Sheet1!\$A:\$A,0),1),"No Match")

If none of that helps and you want to send a workbook, then send it to twogilvy@msn.com telling me what version of excel and specifically what you want to do and where.  (don't just say, "Here's my workbook".)
