Pourquoi c'est le Meilleur Convertisseur CSV vers JSON

Détection Automatique des En-têtes

The first row is automatically used as JSON keys. Each subsequent row becomes a JSON object in the output array.

Inférence de Type Intelligente

Numbers, booleans (true/false), and null values are automatically inferred. Disable type inference to keep all values as strings.

Délimiteurs Personnalisés

Supports comma, semicolon, tab, and pipe delimiters. Perfect for European-style CSVs that use semicolons, or TSV files.

Télécharger JSON

Export the converted result as a .json file ready for use in any API, database import, or application.

Questions Fréquentes

How do I convert CSV to JSON?

Paste your CSV text into the input field and click Convert. The first row is treated as the header and becomes the JSON keys. Each subsequent row becomes an object in the JSON array.

Does it handle quoted fields with commas inside?

Yes. The parser fully supports RFC 4180 CSV, including fields wrapped in double quotes that contain the delimiter character, commas, or newlines.

What if my CSV has no header row?

The tool assumes the first row contains headers. If your data has no headers, add a header row with column names (e.g. col1,col2,col3) before pasting.
