Spreadsheet exports and data dumps often come as CSV, but many applications and APIs expect JSON. This tool reads the first row as column headers and converts every following row into a JSON object, producing an array ready to use in code.
It handles comma-separated values and basic quoted fields, covering the vast majority of everyday CSV exports.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.

Because the calculation or conversion happens instantly as you type, you can experiment freely and see how changing one value affects the result.
Frequently asked questions

Yes, values wrapped in double quotes are treated as a single field even if they contain commas.
What if my columns don't line up on some rows?
