Frequently asked questions
- What is JSON formatting?
- JSON formatting (or pretty-printing) adds indentation and line breaks to JSON data, making it human-readable. Minifying removes all unnecessary whitespace.
- What indentation sizes are supported?
- You can choose between 2 or 4 spaces for indentation, or use tab characters.
- Does this tool work with large JSON files?
- Yes, the formatting happens entirely in your browser. However, very large files (over 10MB) may take a moment to process depending on your device.
