Turn CSV into a clean JSON array of objects — pick the delimiter and infer types. Runs entirely in your browser.
How it works
Frequently Asked Questions
Yes — it follows the CSV standard, so quoted fields containing the delimiter, quotes or newlines parse correctly.
It converts values that look like numbers or true/false into real JSON numbers and booleans instead of strings.
No — the conversion runs in your browser, so nothing is sent to a server.
Convert CSV to JSON online for free. Paste CSV — exported from a spreadsheet or database — and get a clean JSON array of objects using the first row as keys, or arrays if there is no header. Quoted fields containing commas, quotes or line breaks are parsed per the CSV standard, and values that look like numbers or booleans can be inferred automatically. Everything runs in your browser, so your data is never uploaded.
