FAQ

How are headers handled?
JSON to CSV uses the first record's keys as headers; CSV to JSON treats the first row as headers, with comma/semicolon/tab/pipe delimiters.
Will my data be uploaded?
No, conversion is fully local — safe for customer lists, orders and other sensitive tables.
Will special characters break?
Fields containing delimiters, quotes or newlines are auto-quoted per RFC 4180 and import cleanly into Excel.
