- Search - Find keys and values within JSON
- Copy Values - Copy individual values or entire branches
- Error Detection - Highlights JSON syntax errors
Use Cases

- Configuration Files - View and understand config.json files
- Data Analysis - Explore complex data structures
- Debugging - Find issues in JSON payloads

Data Type Indicators
