About CSV to JSON
CSV is the universal spreadsheet export, but code and APIs usually want JSON. This converter parses your CSV — correctly handling quoted fields, embedded commas and newlines — and outputs either an array of objects (keyed by the header row) or an array of arrays.
Everything runs in your browser, so even sensitive data never leaves your device. Pick the delimiter to match your file, then copy or download the JSON.
