Comparing two CSV exports sounds simple until you're dealing with thousands of rows and need to figure out what actually changed.
I built CSVCompare to solve exactly that.
You drop in the before and after CSV files, and it automatically detects the best key and separates the differences into:
- Modified
- Added
- Removed
- Unchanged
Everything runs entirely in the browser. The CSV files aren't uploaded to a server.
I also wanted it to remain useful for larger exports rather than forcing everything into a spreadsheet and manually comparing rows.
Try it here:

This is a small independent experiment, and I'm mainly interested in whether this solves a problem other developers actually have. Feedback is welcome.
