CSV to JSON
Convert CSV data into a JSON array of objects, using the first row as keys.
CSV is easy to export from a spreadsheet but awkward to use in code, where JSON is the natural shape. CSV to JSON turns your CSV into a JSON array of objects, using the header row as keys, right in your browser.

Frequently asked questions
Is the first row used as keys?
Yes — the header row becomes the object keys, and each following row becomes an object.
Does it handle quoted values with commas?
Standard CSV quoting is handled so values containing commas stay intact.
Is my data uploaded?
No — conversion happens in your browser, so your data stays local.
