JSON Formatter & Validator

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 has become the de facto standard for transmitting data between web servers and web applications, commonly used in REST APIs.

Why Use a JSON Formatter?

• Readability: Raw JSON data, especially from an API, is often minified into a single line to save space. A formatter converts this into a beautifully indented, human-readable structure.
• Debugging: Formatting your JSON makes it incredibly easy to spot structural issues and syntax errors like missing commas, mismatched brackets, or incorrect quotes.
• Validation: Our tool automatically validates your JSON as it formats. It will immediately alert you to any errors, saving you valuable debugging time.

Frequently Asked Questions (FAQ)

Is my data safe and private?

Yes. Your privacy is guaranteed. All formatting and validation are performed entirely within your browser (client-side). No data is ever sent to our servers, so your sensitive information remains secure on your machine.

What does "Minify" do?

Minifying is the opposite of beautifying. It removes all non-essential whitespace, such as spaces, tabs, and newlines, to reduce the file size of the JSON data. This is ideal for production environments where bandwidth and speed are critical.

Can this tool handle very large JSON files?

Our formatter is highly efficient and can handle most JSON files with ease. However, for extremely large files (e.g., over 15MB), you may experience some browser slowdown as all processing is done locally. For typical development work, you will not encounter any issues.
