info À propos de cet outil
Convertissez des tableaux JSON au format CSV. Simplifie l'utilisation des données API dans un tableur.

File size: CSV output is typically similar in size to the JSON source, and often smaller since key names are not repeated per row.

Quality: JSON null values become empty CSV cells. Boolean values (true/false) are exported as strings.

help FAQ

What JSON structure is supported?

The converter expects a JSON array of flat objects: [{"key": "value"}, ...]. Arrays of arrays or deeply nested objects are not directly supported.

What if objects have different keys?

All unique keys across all objects are included as columns. If an object doesn't have a particular key, the corresponding cell is empty.

Are nested objects handled?

Nested objects are serialized as JSON strings within a single CSV cell. For complex nesting, consider flattening your JSON before converting.
