Make a new excel workbook.
Copy the sheets from the to excel files you want to compare to this new
workbook. Name one sheet CS_1 and th other CS_2.
Then add two new sheets to this workbook. Name these sheets CS_1_check and
CS_2_check
Put in range A1 on sheet CS_1_check the following formula
=VLOOKUP(CS_1!A1,CS_2!A:A,1,0)
copy this formula to the same range then there are values to compare on
sheet CS_1
All cells with a #N/B as a result are in the sheet CS_1 but not in the same
column in sheet CS_2
Then put in range A1 on sheet CS_2_check the following formula
=VLOOKUP(CS_2!A1,CS_1!A:A,1,0)
also copy this formula to the same range then there are values to compare on
sheet CS_2
All cells with a #N/B as a result are in the sheet CS_2 but not in the same
column in sheet CS_1
With this formula you should get wat you want.
