About CSV to JSON Conversion

The first CSV row is treated as the JSON object property names. Every subsequent row becomes one object in the resulting JSON array.

Quoted CSV values are handled according to standard CSV escaping rules, including commas, quotes, and line breaks inside quoted fields.

You can choose comma, semicolon, tab, or pipe as the CSV delimiter.

Everything runs locally in your browser. Your CSV data is never uploaded to a server.
