About CSV to JSON Converter
How CSV to JSON Converter Works
Parses RFC 4180 CSV records with robust handling for embedded quotes and linebreaks. Maps headers to object keys, auto-casts primitive types, and exports pretty-printed or minified JSON client-side.
CSV to JSON Converter converts tabular spreadsheet data, CSV files, and TSV dumps into structured JSON arrays. It auto-detects column headers, handles multi-line quoted fields according to RFC 4180, and optionally parses numeric and boolean strings into native JavaScript types.
Frequently asked questions
