How it works

CSV is everywhere — exports from spreadsheets, databases, and analytics tools all speak it — but code usually wants JSON. This converter turns a CSV table into a JSON array of objects, using the first row as the field names and each subsequent row as one object.

The parser is quote-aware: fields wrapped in double quotes can safely contain commas, quotes (escaped as ""), and even line breaks, so real-world exports convert correctly rather than splitting in the wrong places. Pick your delimiter — comma, tab, semicolon, or pipe — to match the source file.

The output is pretty-printed and ready to paste into your code or a request body. All parsing happens locally, so confidential spreadsheets never leave your browser.

Examples

A two-column CSV → an array of objects with those two keys.

A quoted value "Smith, John" → kept intact as one field.

Tab-separated export → choose Tab as the delimiter.

Frequently asked questions

Does the first row have to be headers?

Yes — the first row is treated as the field names for every object. Remove or add a header row before converting if needed.

Can it handle commas inside a value?

Yes, as long as that value is wrapped in double quotes, which is the standard CSV convention.

What about tab- or semicolon-separated files?

Choose the matching delimiter from the dropdown before converting.

Is my file uploaded?

No. The CSV is parsed entirely in your browser.
