CSV to JSON Converter
Paste CSV data or upload a .csv file and convert it to JSON — as an array of objects keyed by header row, or as raw arrays. Handles quoted fields, embedded commas and custom delimiters.
About this CSV to JSON Converter
A proper CSV parser — not a naive split on commas — so quoted fields containing commas, quotes and line breaks convert correctly. Numbers, booleans and null are typed automatically in the JSON output. Exports from Excel and Google Sheets convert cleanly; switch the delimiter for European semicolon CSVs or TSVs.
