CSV to JSON Converter
Convert CSV data to a JSON array instantly.
About CSV to JSON Converter
Paste or upload CSV data and convert it to a JSON array of objects where each row becomes an object keyed by the column headers. Supports custom delimiters (comma, semicolon, tab), quoted fields with commas, and optional pretty-printing.
Use Cases
Converting spreadsheet exports for API testing, transforming CSV database exports to JSON for ingestion, preparing data for JavaScript applications, migrating data between systems.
How It Works
Parses the first row as headers, then maps each subsequent row to an object using those header keys. Handles RFC 4180 CSV escaping including quoted fields containing delimiters.
Frequently Asked Questions
Does it handle CSV with commas inside quoted fields?
Yes. Quoted fields like "Smith, John" are handled correctly — the comma inside quotes is not treated as a delimiter.
What if my CSV uses semicolons or tabs?
Select the correct delimiter from the options: comma, semicolon, tab (TSV), or pipe.
