JSON Formatter

Pretty-print JSON so it is easier to read.

When to use this tool?

Use this when raw JSON is hard to scan and you want a prettified version before reviewing, diffing, or sharing it. Example: `{"name":"Apps24"}` becomes neatly indented JSON.

What is JSON Formatter?

JSON Formatter & Validator helps you clean up, organize, and check JSON data online. It is useful for developers, testers, students, and API users who need readable JSON output or want to find syntax errors quickly. If your JSON is difficult to read or not working correctly, this tool makes it easier to format the content and validate whether the structure is correct.

When to use this tool?

Raw JSON is often hard to read, especially when it is compressed into a single line. Formatting adds proper indentation and structure, making it easier to debug, review, and share. A small syntax mistake in JSON can break an API request, configuration file, or app feature. Validation helps detect problems such as missing commas, invalid brackets, or incorrect quotation marks before you use the data elsewhere.

Examples

  • Minified API responses
  • Configuration files that are hard to scan
  • JSON copied from logs or browser devtools

How to use JSON Formatter

1. Paste your JSON into the input box. 2. Click the format or validate button. 3. Review the formatted result or check the error message.
