How does the JSON validator work?

It parses your text input using standard JSON specifications. If it encounters syntax errors (like missing commas or unclosed brackets), it flags the exact issue.

Is my JSON data kept private?

Yes. The parsing and formatting are executed locally using client-side JavaScript. Your data is never transmitted to our servers.

Can I format invalid JSON?

No. The formatter requires standard compliant JSON code. You will need to resolve syntax errors pointed out by our validator first.

What is the difference between Beautify and Minify?

Beautify adds line breaks and spaces to make JSON readable for humans. Minify strips all white space to minimize file size for network transfers.

Does this tool support nested arrays and objects?

Yes, our formatter supports complex, deeply-nested JSON structures and arrays of any depth.

Why did my JSON validation fail?

Common causes include trailing commas after the last item, single quotes instead of double quotes, or missing double quotes around property keys.

Can I load files into this tool?

You can copy and paste the contents of any JSON file directly into the input editor for formatting.

Is there a limit on the JSON size?

There is no set limit, but processing extremely large JSON payloads (multi-megabyte files) might temporarily freeze your browser tab.

What is JSON-LD schema markup?

JSON-LD is a JSON-based method of encoding structured data for search engines. You can format it here, or generate it using our JSON-LD Schema Generator.

Can I use this tool on a phone?

Yes, the layout is fully responsive and works seamlessly across desktops, tablets, and smartphones.
