About JSON Formatting
What is JSON?
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format. It's easy for humans to read and write, and easy for machines to parse and generate.
Common Use Cases
- API responses and requests
- Configuration files
- Data storage and transmission
- Web application data exchange
Format vs Minify
Format: Adds indentation and line breaks for readability.
Minify: Removes whitespace to reduce file size for production.
Privacy & Security
All processing happens in your browser. No JSON data is sent to our servers, ensuring your information stays completely private and secure.
