Invalid JSON
What does this tool do?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. While easy for machines to parse, raw JSON often comes minified (single line), making it hard for humans to read.
This JSON Formatter & Validator takes your raw JSON string and:
- Formats it with proper indentation (pretty-print) for readability.
- Validates the syntax to ensure it adheres to JSON standards.
- Minifies the code to reduce file size for production use.
Is this tool secure?
Yes. This tool works entirely on the client side. No data is sent to any server. All processing happens locally within your web browser using JavaScript's native capabilities. You can even disconnect your internet and the tool will still function.
