FAQ

Is my JSON uploaded or stored?

Your data is processed locally in the browser. We do not upload JSON to servers. Feedback data is stored locally and can be cleared anytime.

Why does parsing stop for very large JSON?

To prevent memory issues, real-time parsing is disabled when input exceeds capacity. You can still format/minify via streaming workers.

Does the tool work on mobile and different browsers?

Yes. JSON Lab is responsive and works on modern browsers. Performance varies with device capability.

How to avoid crashes with malformed input?

Fix lint errors indicated by the editor. Visualization and preview are disabled for invalid JSON until corrected.
