Looking for a code that active workbook "Data 1" out of various opened workbooks, then delete
rows by pairs if values match on columns A, D, F, K and the rows have opposite numbers in column J.
The code would be saved in a personal workbook, not in the workbook named "Data 1".
Attached is a sample of the workbook "Data 1" (the original can have over 30k rows).
Thanks in advance.
