About
CSV to JSON turns flat spreadsheets into clean JSON arrays on your computer. The delimiter (comma, semicolon or tab) is detected automatically, the first row becomes the keys, and Cyrillic and diacritics survive thanks to BOM-aware reading. Empty rows are skipped, duplicate column names get numeric suffixes instead of overwriting each other.
Free converts 5 files a day. Pro removes the limit and adds formatted (pretty-printed) JSON output. One key covers up to 3 Windows PCs.
