# JSON Validation and Formatting
JSON (JavaScript Object Notation) is the de facto standard for data exchange on the web. However, its strict syntax makes it prone to human errors when edited manually.This tool allows you to validate the structure, format the code to improve its readability, and automatically repair common syntax errors.Common Errors it Repairs
- Single Quotes: The JSON standard requires double quotes. The tool converts
'key': 'value'to"key": "value". - Unquoted Keys: Detects JavaScript-style object keys and adds the necessary quotes.
- Trailing Commas: Removes commas at the end of objects or arrays (trailing commas) that break the strict parser.
Features
- Syntax Highlighting: Colours keys, strings, numbers and booleans to facilitate quick reading.
- Real-Time Validation: Instantly indicates whether the JSON is valid or shows the specific parsing error.
- Total Privacy: Processing happens 100% in your browser. No data is sent to external servers.
