What is a JSON Formatter?
The JSON Formatter (also known as a JSON Beautifier or Pretty Printer) is a developer tool that converts compact, minified JSON data into a readable, indented structure. It also validates the syntax to ensure your JSON is RFC-compliant.
JSON (JavaScript Object Notation) is the backbone of modern APIs. However, servers often send it as a single compressed line to save bandwidth. This makes it impossible for humans to read or debug.
This tool solves that by adding proper whitespace and line breaks. It's the first step in debugging any API integration issue. Conversely, the 'Minify' feature allows you to compress your JSON back into a single line for production usage.
1How to Use
- Input Data: Paste your JSON string into the large text area.
- Format: Click 'Format' to apply indentation (pretty print).
- Minify: Click 'Minify' to remove all unnecessary whitespace.
- Validate: Click 'Validate' to check for syntax errors without changing the format.
- Copy: Use 'Copy Result' to grab the processed JSON.
★Key Features
- Syntax Validation: Instantly identifies structural errors like missing commas or quotes.
- Dual Mode: Switches effortlessly between Human-Readable (Beautified) and Machine-Optimized (Minified).
- Large Payload Support: Optimized to handle large API responses without freezing.
- Error Reporting: Provides descriptive error messages indicating why the JSON is invalid.
- Secure Processing: All parsing happens locally in your browser.
