What this tool does

Private by design

Everything runs locally in your browser with JavaScript. Your data is never uploaded, which makes the tool safe for sensitive content, and it keeps working offline.

Frequently asked questions

Is my data sent to a server?
No. Everything runs locally in your browser and nothing is uploaded, so the tool is safe even for sensitive data.
Does sorting keys change my data?
No. Only object keys are reordered alphabetically and recursively; values, arrays and nesting are untouched.
