Your files never leave your browser

Your files never touch our servers

Excel Change Tracker runs entirely in your browser. There are no servers receiving your files — we literally cannot see what you compare. Close the tab and everything is gone.

Frequently asked questions

Are my Excel files uploaded to a server?+

No. Everything runs in your browser. Your files never leave your device and are never sent to any server.

What types of changes does it detect?+

It finds rows that were added, removed, or modified between the two file versions.

Does it work with CSV files?+

Yes, it supports both .xlsx and .csv files.

Can I compare files with different column structures?+

The tool works best when both files share the same column headers. Mismatched columns may produce unexpected results.

Is there a file size limit?+

No strict limit — processing happens in your browser so performance depends on your device memory.

Is Excel Change Tracker free?+

Yes, free for 5 uses per month with no signup. Upgrade to Pro for unlimited uses at €10/month.
