Convert CSV to JSON online
Move tabular data between a spreadsheet-friendly CSV format and a developer-friendly JSON array. The converter handles quoted commas and line breaks in CSV fields.
Useful for small data handoffs
Use it for API examples, quick exports, test fixtures, and one-off data cleanup when you want the data to stay on your device.
Does it upload my CSV?
No. The conversion happens in your browser, and the site does not receive the table you paste.
