JSON Formatter
Prettify and validate JSON code.
Understanding the JSON Formatter & Validator
JSON (JavaScript Object Notation) has become the universal standard for web data transmission and application configuration. However, raw JSON payload returned by APIs or saved in files is often compressed into a single line, making it extremely difficult to read, debug, and trace syntax issues.
Oyaam's JSON Formatter allows you to immediately beautify, minify, and validate JSON structures locally. It catches syntax errors, displays clear line-by-line debugging messages, and reformats the tree using standard indentation settings.
Key Features
- Smart Validation: Instantly check JSON validity and identify exact characters or lines causing parsing issues.
- Custom Indentation: Format code using 2 or 4 spaces depending on your team's code style standards.
- Payload Minification: Condense formatted JSON into a single line to save bandwidth and storage size.
How to Format JSON
- Paste your raw or minified JSON text into the workspace textarea.
- Click "Beautify" to format with spaces, or "Minify" to compress the text.
- Use the "Validate" button to verify compliance with official JSON standards.
