Excel/Compare data in two columns to find matches
I have two columns of addresses, column A which has 13995 rows of addesses and column B which has 2257 rows of addresses. I need a formula that will tell me which addresses in column B are also in column A. Thank you for your time and expertise. Amy
This Conditional Format will highlight all the duplicates in Column A.
Click on the letter A to highlight the entire column
Go to Conditional Formatting
Excel 2003: Go to Format>Conditional Formatting and select Formula is, type in =(COUNTIF($B:$B,A1)=1)*(A1<>"") change the Format to Fill and the color of your choice and click on OK and OK. The duplicates are now highlighted in Column A
Excel 2007 and 2010: Go the Home Tab and click on Conditional Formatting and select New Rule > Use a formula, in the Format Values where this formula is true type in =(COUNTIF($B:$B,A1)=1)*(A1<>"") and change the format to Fill and the color of your choice. Click on OK and OK. The duplicates are now hightlighted in column A.
Hope this helps.
