About XLSX to JSON conversion

This tool reads the first sheet, uses row one as keys, and emits a pretty-printed JSON array in one step, with no CSV detour and no data leaving your machine.

How to convert XLSX to JSON

  1. Drop your XLSX files onto the box above, or click Choose files.
  2. The output format is already set to JSON — adjust it per file if you need something else.
  3. Click Convert, then download your JSON files (or everything as one ZIP).

Free, no account, no watermarks — and because the conversion runs in your browser, your files are never uploaded to a server.
