How it works

Copy-pasting data between tools is where mistakes happen: a CSV export goes into a JSON endpoint, a query string has to become a readable table, an XML dump should end up as SQL. This converter reads JSON, CSV, TSV, XML, YAML, key=value or query strings and plain line lists, detects the format automatically and writes the result in ten output formats. CSV parsing follows RFC 4180, so quoted fields with commas, line breaks and doubled quotes stay intact. Delimiters can be sniffed or set by hand, the first row can be treated as data, nested JSON keys can be flattened to dot notation, and for SQL you choose the table name. Everything runs locally in your browser — useful for client data, exports and logs that should not be sent to a random server.
