About the JSON to CSV
Paste a JSON array of objects and convert it into a CSV table. The tool collects all keys into a header row and writes one line per object, quoting values that contain commas, quotes or line breaks.
Conversion runs entirely in your browser, so your data is never uploaded — then open the CSV in any spreadsheet app.
