Feature Reference

Getting Started

Paste or type your JSON into the left editor. The tool instantly checks your JSON as you type:

✓ Valid  JSON appears normally in the editor.

✗ Invalid  JSON shows an error message in red.

The output box updates automatically whenever you apply formatting or conversions.

Features & Tools

How Conversion Works

Select a conversion from the "Convert" dropdown and choose your target format — XML, CSV, or YAML.

If the JSON is valid, the converted result appears automatically in the output box.

Note: If your JSON contains errors, the tool highlights them in red instead of converting. Fix the errors first, then convert.

Validation & Error Handling

JSON is validated in real time as you type.

Beautify, Minify, and Convert actions only run when JSON is valid to ensure accurate output.

Dark Mode

Switch between light and dark mode using the toggle button in the top-right corner of the navbar.

All editors, buttons, panels, and backgrounds adapt automatically. Your preference is saved in your browser so it persists across visits.
