Merge every company list
into one clean spreadsheet.

Upload as many Excel files as you like — this tool pulls in every worksheet, stitches the rows together, and tags each record with the file and sheet it came from. Export to Excel or CSV in one click.

What this app does for you

1. Upload many files

Drop in any number of .xlsx or .xls files at once. Every worksheet inside each file is read automatically.

2. Auto-tag the source

Every row gets two extra columns — Source File and Source Sheet — so you always know exactly where each company came from.

3. Download or reset

Export the consolidated list as Excel or CSV. Hit Reset any time to start fresh with a new batch — nothing is stored on a server.

100% private. All processing happens locally in your browser. Your files are never uploaded anywhere — close the tab and they're gone.

Click to upload Excel files

.xlsx, .xls — multiple files supported

Enjoying the tool?

This tool is 100% free and built in my spare time. If it saved you an afternoon of copy-pasting spreadsheets, consider fuelling the next update with a coffee — every cup directly funds new features and keeps the app ad-free.
