JSON Explorer — Free Online Viewer

JSON Explorer lets you open and explore JSON directly in the browser. All processing happens client-side in your browser, with nothing sent to a server. Free, unlimited, and no registration needed.

How to use JSON Explorer

1. Paste your content or select a file.
2. Explore the parsed structure.
3. Copy out any part you need.

Frequently asked questions

Are my files uploaded?

No. Files are read locally by your browser and never transmitted.

What file sizes are supported?

Sizes into the tens of megabytes are fine — the limit is your browser's memory, not a server quota.

Do I need to install a plugin?

No. Everything runs with standard browser features.
