CSV to JSON Converter
Convert CSV to JSON in your browser. Quoted commas, escaped quotes and multiline fields are parsed correctly — the first row becomes your object keys. No upload, 100% private. It runs entirely in your browser — no signup, no installation, and nothing you paste or drop leaves your device.
How to Convert CSV to JSON
This CSV to JSON converter turns spreadsheet data into clean JSON you can use in APIs, scripts or databases. Paste your CSV on the left — or open a .csv file directly from your computer — and values in quotes with commas inside, escaped quotes or even multi-line fields are parsed correctly, so your columns never shift. The first row becomes the object keys and each following row becomes one JSON object in the result array. The tool auto-detects the delimiter, but you can also switch between comma, semicolon and tab, and optionally convert numbers and booleans to real JSON types. Everything runs in your browser: your data is never uploaded, and you can copy the JSON or download it as a .json file.
