JSONPath Syntax Guide
| Expression | Description | Example |
|---|---|---|
| $ | Root element | Entire JSON object |
| $.property | Direct property access | $.store, $.user.name |
| $[0] | Array element by index | First item in array |
| $[*] | All array elements | $.books[*].title |
| $.* | All object properties | $.store.* |

Frequently Asked Questions
What JSONPath features are supported?
Our implementation supports basic JSONPath syntax including root access ($), property access, array indexing, wildcards (*), and nested navigation. Advanced filtering is coming in future updates.
Can I save and reuse queries?
Currently, you can copy query results and download them as JSON reports. Query saving and management features are planned for future releases.
How large JSON files can I query?
The tool can handle reasonably large JSON files, but performance depends on complexity and browser resources. For very large datasets, consider breaking them into smaller chunks.
Are query results accurate?
Yes, our JSONPath implementation follows standard specifications and provides accurate results. All queries are processed locally in your browser with real-time validation.
