How to use it

- Pick Merge or Split by a column (and type the column header).
- Press Run and download.
Merging lines columns up by their header name, even when files have columns in a different order, and can add a Source file column so you know where each row came from. Row totals are checked: rows in = rows out.
What you get
- Merged workbook or ZIP of split files
- Reconciliation: rows in = rows out
Good to know

Questions
My files have different columns — can I still merge?
Yes. Every column from every file is kept; missing values are left blank.
How do I split a file by region?
Choose Split and type the header, for example Region. You get one file per region.
