About CSV to JSON

CSV (comma-separated values) is common in spreadsheets and exports. Converting to JSON makes it easy to use in APIs, configs, or JavaScript. This tool parses CSV in your browser and outputs valid JSON — with optional headers as object keys.

Frequently Asked Questions

Can I use a different delimiter?

Yes. Select comma, semicolon, or tab. The first row can be treated as headers so you get an array of objects; otherwise you get an array of arrays.

Is my data sent to a server?

No. Conversion happens entirely in your browser. Your CSV never leaves your device.

What if my CSV has commas inside quoted fields?

The parser respects double-quoted fields. Commas inside quotes are treated as part of the value, not as delimiters.
