How to Use
- Pretty print a minified API response to make it human-readable.
- Validate JSON configuration files before deploying to production.
- Minify JSON payloads to reduce file size for network transmission.
- Debug malformed JSON by seeing exactly where the syntax error occurs.
How It Works
JSON (JavaScript Object Notation) is a lightweight data-interchange format widely used for APIs, configuration files, and data storage. Properly formatted JSON is essential for readability and debugging.
This tool parses your JSON input and re-serializes it with consistent 2-space indentation (format mode) or no whitespace (minify mode). If your JSON contains syntax errors, the tool displays the error message to help you identify and fix the issue.
Frequently Asked Questions
JSON formatting (also called pretty printing) adds consistent indentation and line breaks to make JSON data human-readable. Minified JSON has all unnecessary whitespace removed to reduce file size.
Minified JSON takes up less space, which reduces bandwidth usage when transmitting data over networks and decreases storage requirements. It is commonly used in production environments for API responses.
JSON validation checks that the input follows the JSON specification: correct use of curly braces, square brackets, colons, commas, and properly quoted strings. The tool reports the specific error and location if the JSON is invalid.
