Comparing two spreadsheets

[Morten]

Hi I have a problem comparing two spreadsheets of data/names.

The problem:

I have two lists with account names and numbers in coulumns A and B on sheet 1 and 2
Sheet 1 and 2 differ from each other in contents as well as number of accounts.

Is it possible to compare the two sheets and show duplicate entries in a 3rd sheet??? (blanck sheet).
In addition the two lists have a huge amount of data which make comparing in the same sheet difficult.......

Have tried various formulas but have not yet succeded

Hope that some of you can help

Copy first columns A1 to B3147 (or whatever amount of lines there is) from Sheet 1 and paste them into Sheet 3!A1. The data will then lie in the same block as in Sheet 1.

Then copy A1 to B8116 ( or whatever amount of lines there is in this sheet) from Sheet 2 and paste them into Sheet 3 below the first ones. In this example they will lie in the block from A3148 to B11263.

In C1 write =IF(A1=A2;A1;""). Perhaps you must use comma instead of semicolon

Copy C1 all the way down and include also column D

Sort column A and B by A and you will see all the A duplicates in column C

Sort column A and B by B and you will see all the B duplicates in column D
