Compare Two Files

Drop two files in and see what changed between them, whether text, JSON or CSV. Everything is compared locally in your browser.

Runs entirely in your browser — your file is never uploaded.

Questions

What kinds of file can I compare?
Plain text of any sort, including code, Markdown and logs, plus JSON and CSV which get structure-aware comparisons rather than line-by-line ones.
Can I save the differences?
Yes. The differences can be exported as a patch file, which you can attach to a ticket or apply to the original with standard tooling.

Or open the full Diff tool.
