What tools are included in the JSON Formatter?
It includes a JSON prettifier, minifier, a powerful tree-view explorer, and a syntax validator.
Is my JSON data safe here?
Yes. Processing is 100% client-side. Your data never leaves your browser and is not sent to any server.
Can the tool fix broken JSON?
It highlights syntax errors (like missing commas or quotes) to help you fix them manually. It doesn't automatically 'guess' the fix for major errors.
What is 'Tree View'?
Tree View allows you to expand and collapse nested JSON objects, making it easy to navigate very large data structures.
Can I search within the JSON?
Yes. The tree view and text view support standard browser search (Ctrl+F), helping you find specific keys or values quickly.
Does it support large JSON files?
It can comfortably handle files up to several megabytes. For extremely large files (100MB+), browser performance may vary.
Can I minify my JSON for production?
Yes. Use the 'Minify' button to remove all whitespace and newlines, reducing the payload size for your API calls.
Does it highlight different data types?
Yes. Strings, numbers, booleans, and nulls are color-coded for better readability.
Can I copy the formatted JSON directly?
Yes. A one-click copy button allows you to grab the output instantly.
Is this tool free for developers?
Yes. Everything in the Dev-Toolkit is free and intended for professional use by developers and QA engineers.
