JSON Beautifier
The JSON Beautifier transforms minified or messy JSON into clean, readable, well-structured format with proper indentation and line breaks. It adds consistent spacing, organizes nested objects and arrays, and makes complex JSON structures easy to navigate. This tool is perfect for debugging API responses, reading configuration files, or understanding data structures from third-party services. Beautiful JSON is easier to maintain, review, and share with team members.
Formula
Beautification adds: - Indentation (2 or 4 spaces) - Line breaks after each key-value pair - Space after colons - Newlines after commas - Consistent formatting throughout Result: Human-readable JSON
Example
Input (minified): {"user":{"name":"Alice","roles":["admin","editor"]},"active":true} Output (beautified): { "user": { "name": "Alice", "roles": [ "admin", "editor" ] }, "active": true }
How to Use
- Paste your minified or messy JSON into the input
- Select indentation size (2 or 4 spaces)
- Click beautify to format the JSON
- Review the clean, readable output
- Copy the beautified JSON for your use
Frequently Asked Questions
What is the difference between beautify and format?
They are essentially the same thing. Both terms refer to adding indentation, line breaks, and spacing to make JSON readable. 'Beautify' emphasizes the visual improvement, while 'format' is the more technical term.
What indentation level should I use?
2 spaces is the most popular choice and is used by most style guides. 4 spaces provides more visual hierarchy but takes more horizontal space. 1 tab is less common. Choose based on your team's preference.
Can beautify fix invalid JSON?
No. Beautify only works on valid JSON. If your JSON has syntax errors, you need to fix them first. Use the JSON Validator to identify and fix errors before beautifying.
Does beautification change the data?
No. Beautification only adds whitespace for readability. The actual data, keys, values, and structure remain identical. A parser reads beautified and minified JSON the same way.
How do I beautify JSON in my code editor?
Most editors have built-in JSON formatting: VS Code (Shift+Alt+F), Sublime (Ctrl+L then Ctrl+I), and IntelliJ (Ctrl+Alt+L). This online tool is useful when you do not have an editor handy or need to share formatted JSON.
