Drag ANY CSV/XLSX/JSON file (yes, even gigantic ones) into your browser, write SQL queries, and get instant results. No uploads, no servers, no nonsense.

Try it out here: https://datakit.page

Built with: DuckDB-WASM, React, and a ton of performance optimizations to make browser-based analysis actually usable.

I need your help: What features would make this more useful for you? Any specific use cases I should optimize for? Found any bugs or have ideas for improvements?

Looks neat, thanks!

Unfortunately the first file I tried it on it didn't do anything useful because that file had header and footer lines (FTSE market files have descriptions in the first 2-3 lines and an XXXXXXXXXX marker on the last line).

Can you add an option to drop the first X and last Y lines? That's pretty common for things like pandas.read_csv() etc...

I also found the Excel-like grid display mildly misleading because the first thing I did on your opening page was click on a cell and start typing "=..." and that didn't do anything. If it looks like an Excel grid, I'm going to try and use it like an Excel grid
