Frequently Asked Questions (FAQ)

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of JavaScript and is commonly used for transmitting data in web applications.

How do I use the JSON Formatter?

Simply paste your JSON data into the editor on the left, or fetch JSON from a URL. The tool will automatically format and validate your JSON. You can also paste JSON directly - it will be auto-formatted instantly! Use the Format button to beautify, Minify to compress, or Clear to start fresh.

What is the Graph Visualization feature?

The graph visualization on the right displays your JSON data as an interactive node tree. You can click on nodes to expand/collapse them, navigate through complex JSON structures, and click on any value to jump to its location in the editor. This makes it easy to understand and navigate large JSON files.

Can I fetch JSON from an API?

Yes! Enter any URL in the input field at the top and click "Go". The tool supports GET, POST, PUT, DELETE, and PATCH methods. You can also configure custom headers and request body in the settings dialog.

Does it work offline?

Yes, once the page is loaded, all JSON formatting, validation, and visualization features work entirely in your browser without requiring an internet connection. However, fetching JSON from URLs requires an active internet connection.

Is my data secure?

Absolutely! All JSON processing happens locally in your browser. Your data is never sent to any server (except when you explicitly fetch from a URL). Your JSON data remains private and secure.

What browsers are supported?

This JSON Editor works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. Both light and dark modes are supported based on your system preferences.
