Question

I have two columns (A and B) with numbers. I need to sort by matching number from Col A and Col B, so that I can see which ones of them match.

Col A–Col B

2333–1222

2445–2333

2500–2400

2501–2445

..etc

I need it to look like this:

Col A–Col B

xxxx–1222

2333–2333

xxxx–2400

2445–2445

2500–xxxx

2501–xxxx

etc..

EDIT: I copied the values from Col B to Col A and sorted smallest to largest. This matches the values. Now I need to delete the ones that don’t have duplicates. Ideas?

Thank you!

Taken from here

Use this formula in Column C all the way to the end of your data and then sort.

IF(ISNUMBER(MATCH(A2,B:B,0)),A2,"")
