Frequently asked questions

Is the JSON to XLSX converter free?

Yes. Conversions are free, with files up to 100 MB on the free plan (Pro raises this to 2 GB). There is no watermark and no sign-up.

Is my JSON file uploaded to a server?

No. The JSON-to-XLSX conversion happens entirely in your browser. Your file is processed in memory on your device and never sent anywhere.

How long does the conversion take?

Small images and documents are usually done in seconds. Large files, and long videos in particular, take longer because your own device does the work; a progress bar keeps you posted.

Do I need to install anything?

No installs and no extensions — everything runs in the page you're on, on desktop and mobile.
