Frequently asked

Does the tool match columns by header names?

No, data rows are merged based on column position (Column A to Column A), so ensure all CSV files share the same column layout.

Are sensitive customer transactions uploaded to a server?

No, the entire CSV parsing and XLSX generation process runs locally within your client browser.
