How It Works
Paste CSV data or upload a CSV file, and the tool automatically converts it to JSON format. The first row is treated as headers and becomes the JSON object keys. Each subsequent row becomes a JSON object in an array. You can choose between different JSON output styles: array of objects, compact format, or pretty-printed with indentation. The tool handles quoted values, escaped commas, and various CSV dialects. You can copy the JSON or download it as a .json file. All processing happens in your browser.
