Strings inside JSON
CSV vers JSON et échappement pour les imports. Les très gros fichiers peuvent ralentir l’onglet — travaillez par morceaux.
Convert between formats
CSV to JSON turns spreadsheet rows into arrays of objects. JSON to YAML helps when a config file needs to move between formats. Each page explains what it does and what it does not attempt.

Frequently asked questions
JSON Formatter or JSON Editor—which should I use?
The formatter is fastest for one-box beautify or minify. The editor adds tree/table modes, repair, transforms, compare, and schema validation.
JSON Stringify vs JSON Unstringify?
Stringify wraps text as a JSON string value. Unstringify parses an already-quoted JSON.stringify result back to text. Unstringify also includes a stringify mode for the reverse.
Is my JSON uploaded to a server?
These tools run in your browser after the page loads. Copy or download when you need to share output elsewhere.
