info À propos de cet outil
Convertissez des données CSV en objets JSON. Un utilitaire rapide pour les développeurs.

File size: JSON output is typically similar in size to the CSV source — sometimes slightly larger due to key names being repeated per object.

Quality: The first row must contain headers. Rows with fewer columns than the header are padded with null values.

help FAQ

What does the output look like?

The output is a JSON array of objects: [{"name": "Alice", "age": "30"}, {"name": "Bob", "age": "25"}]. Each CSV row becomes one object.

Are numbers converted to numeric JSON types?

Yes. Cells that contain only numeric values are output as JSON numbers. Text values are output as strings.

What if my CSV has missing values?

Missing values in a row produce null for that key in the corresponding JSON object.

Can I convert a large CSV?

Yes, files up to 100 MB are supported. Very large files with millions of rows may take a few seconds to process.
