This converter reads a CSV file and produces a JSON array where each row becomes an object keyed by the header row. It follows RFC 4180 parsing rules, which is what separates it from a naive split on commas: a quoted field may itself contain commas, line breaks and doubled quote marks, and all three are handled correctly. Blank cells become empty strings rather than being dropped, so every object keeps the same shape and your downstream code does not have to guard against missing keys. It is the fastest route from a spreadsheet export to seed data, an API fixture or a config file, and because the parse runs in your browser, customer exports never leave your machine.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
