About this tool

CSV-to-JSON conversion turns spreadsheet exports into arrays of objects for APIs, apps and databases. This parser handles the tricky parts: quoted fields, embedded commas, escaped double quotes and different delimiters (comma, semicolon, tab — auto-detected or manual). The first row becomes object keys. Reverse JSON-to-CSV is on the roadmap.

FAQ

What if my data has commas inside values?

Wrap those fields in double quotes — the parser reads quoted sections correctly, including "escaped" quotes.

How is the delimiter chosen?

Auto-detect compares comma, semicolon and tab counts in the header line; you can also force one.

What about numbers and booleans?

Values that look like numbers/true/false are converted to real JSON types (toggle to keep strings).
