About CSV to JSON converter

The CSV to JSON converter pastes CSV data and outputs JSON. A switch button on the page swaps to JSON to CSV mode without navigating away — both directions live on the same tool page. Paste comma-separated or tab-separated values and the tool parses them into an array of objects. Useful for preparing spreadsheet data for APIs, importing into JavaScript applications, and converting export files for programmatic use. The JSON to CSV converter shares this page and is accessible via the direction toggle.
