Does it handle quoted fields with commas?

Yes. Fields wrapped in double quotes containing commas are parsed correctly. The parser tracks whether it is inside a quoted field before treating a comma as a delimiter.

What if a field contains a double quote?

Two consecutive double quotes inside a quoted field are treated as an escaped single double quote, following the CSV standard.

Does the first row have to be headers?

Yes. The first row is always used as the key names for the JSON objects. If your CSV has no header row, the first data row will be used as keys.

Is my data sent to a server?

No. The conversion runs entirely in your browser. Nothing is transmitted.

About CSV to JSON Converter

Importing CSV data into a JavaScript application or API requires converting it to JSON first. This converter parses CSV using a proper field parser that handles quoted fields containing commas, escaped double quotes (two consecutive double quotes inside a quoted field), and multi-line values. The first row is used as the key names for each object. Each subsequent row becomes one object in the output array. The output is formatted with JSON.stringify(data, null, 2) for readability. Click Convert to generate the JSON, then copy from the output panel. Developers importing spreadsheet exports into a Node.js script, data analysts converting CSV reports to JSON for further processing, and anyone who needs to feed CSV data into a JSON-based API are the primary users. Runs entirely in your browser.
