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 the JavaScript Programming Language.
Format, validate, and beautify your JSON data with our free online JSON formatter. Fix syntax errors and make your JSON readable with proper indentation.
Our JSON Formatter provides an easy way to format and validate JSON data. Simply paste your JSON into the input area, and the tool will automatically format it with proper indentation and line breaks. The validator will check for syntax errors and highlight any issues.

The tool will highlight any syntax errors in your JSON. Common issues include missing commas, trailing commas, unquoted property names, and invalid characters. The error message will indicate the line and position of the issue.
Minified JSON removes all unnecessary whitespace to reduce file size, while formatted JSON adds indentation and line breaks to make the structure more readable. Both contain the same data, just presented differently.
The tool can handle most JSON documents, but very large files (several MB) might affect browser performance. For extremely large JSON files, consider using a desktop application.
Standard JSON doesn't support comments. If your JSON contains comments (which is not valid JSON), you'll need to remove them before formatting. Some JSON parsers support comments using special properties or non-standard extensions.
