About JSON Formatting

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy to read and write, and also easy for machines to parse and generate.

• This tool automatically sorts JSON by key names, making the structure clearer
• Uses 2-space indentation for better readability
• Detects JSON syntax errors in real-time and provides error prompts

Formatting JSON is useful for debugging API responses, editing configuration files, and data analysis. If your JSON contains sensitive information, rest assured that all processing is done in your browser and will not be uploaded to any server.
