Hey Product Hunt 👋 I'm Matt, a data scientist by day. I made Juxx to scratch my own itch. Comparing two versions of a spreadsheet on a Mac was a cognitive slog so I made the tool I wanted. It runs 100% locally (WASM, nothing leaves your machine), diffs 10k+ rows in milliseconds, and renders spreadsheets so I can actually see what changed instead of squinting at raw text. Juxx started as a browser tool (diff.sandy.ms) and people kept asking for a native app, so here it is. Would love your feedback, especially on file formats and edge cases you'd want supported next. Happy to answer anything!

Does it support Excel files directly, or do you need to export to CSV first?

@karimbenkeroum Supports xlsx files directly! The plan is to support parquet files as tabular data as well, but that'll be a few weeks out I think.
