How to use this JSON Tool
JSON (JavaScript Object Notation) is the language of the web, but raw JSON often looks like a messy wall of text. Our JSON Formatter creates readable, organized code structures instantly.
Features:
- Prettify: Formats compact JSON into a readable tree structure with proper indentation (2 spaces).
- Minify: Removes all unnecessary whitespace to reduce file size for production usage.
- Validate: Checks for syntax errors (like missing commas or unclosed brackets) and tells you exactly where the problem is.
Why Validate Offline?
Many online validators send your data to their backend servers for processing. At NanoKito, we prioritize your privacy. Your sensitive data (API keys, user configs, etc.) is processed entirely within your browser using JavaScript's native JSON engine. Nothing is ever uploaded.
