Frequently asked questions
Can files with different column headers be merged?
No. Rename and reorder the columns first. This tool appends rows; it does not match records by an ID.
Are duplicate rows removed during a merge?
No. Every data row is appended in file order. Use Remove Excel duplicates on the result if needed.
