JSON VIEWER · BROWSER-LOCAL

Make sense of your JSON.

Paste JSON or open a local file to validate it, format or minify it, and explore the structure as an expandable tree. The viewer processes document contents in this page and does not upload them.

Browser-first · clear inputs · no account for the free tool

01

Read the shape quickly

Switch between formatted text and an expandable tree for nested objects and arrays.

02

Catch syntax issues

Invalid JSON reports an actionable line and column so you can find the problem.

03

Keep files on this device

Paste text or choose a local JSON file. The app processes its contents in the browser and does not send them to a MiicroApps processing server.

FAQ

A few useful answers.

Does the viewer upload my JSON?

The viewer processes the entered text and local file contents in the page. Its app code does not upload document contents or filenames. Browser extensions and device-level services are outside its control.

Can I use a file from CSV Cleaner?

Yes. Download the JSON from CSV Cleaner, then open that file here. The two tools do not transfer document contents directly between apps.

What is the file size limit?

The viewer accepts JSON text or files up to 5 MB.

Can it repair invalid JSON automatically?

No. It validates syntax and points to the error location; it does not silently rewrite invalid input.

Can I save my result?

You can copy the formatted text to your clipboard or explicitly download a local JSON file.
