Why use this tool?

Spreadsheet exports come as CSV, but most APIs and apps expect JSON. Converting by hand is tedious and naive splitting breaks on quoted fields containing commas. This parser handles quotes, escapes, and custom delimiters correctly.

Common use cases

Seeding databases

Turn a CSV export into JSON to import into an app or database.

API payloads

Convert tabular data into a JSON array of objects for requests.

Data wrangling

Frequently asked questions

Does it handle quoted commas?

Yes. Fields wrapped in double quotes can contain commas, line breaks, and escaped quotes ("").

Yes. Pick comma, semicolon, or tab from the delimiter dropdown.

Is my data uploaded?

No. Parsing happens entirely in your browser.
