How to Format and Validate JSON?

JSON (JavaScript Object Notation) is the language of the web, but raw JSON often looks like a messy wall of text. Here is how to clean it up:

1. Paste JSON: Copy your raw JSON string and paste it into the large editor area.
2. Format (Beautify): Click the "Format / Validate" button. The tool will parse your code, applying proper indentation (2 spaces) and line breaks.
3. Minify: If you need to save space (e.g., for production), click "Minify" to remove all unnecessary whitespace.
4. Validate: If there is a syntax error (like a missing comma), the tool will show an error message pointing to the issue.

Why use CodeCoffeeTools JSON Formatter?

• Instant Validation: Don't let a missing bracket break your app. Catch syntax errors before you deploy.
• Local Processing: Unlike many API-based formatters, this runs entirely in your browser memory.
• Collapsable Nodes: (Coming Soon) We are working on an interactive tree view to collapse objects and arrays.

Is it Safe to Paste API Keys or Data?

Yes, absolutely. We understand that JSON often contains sensitive user data or private keys.

Because CodeCoffeeTools operates with a client-side architecture, the data you paste into this text area never leaves your computer. It is processed using JavaScript in your own browser. We have no way of seeing or storing your data.
