Feat: Add JSONPath Query Support for Dynamic JSON Data Extraction.
Title
Feat: Add JSONPath Query Support for Dynamic JSON Data Extraction.
Type
New Feature
Description
This feature will allow users to input a JSON object and specify a JSONPath expression to extract specific data points efficiently.
Key Features:
- JSON Input: Users can provide JSON data to be queried.
- JSONPath Query: A field to enter JSONPath expressions for dynamic filtering.
- Query Results: Extracted data will be displayed based on the query provided.
- Error Handling: Gracefully handles invalid JSON or malformed JSONPath queries, ensuring reliability.
Use Case
Dynamic JSON Data Extraction with JSONPath
Use Case Overview
A developer is working with a JSON response from an API and needs to extract specific data points dynamically. Instead of manually traversing the JSON structure or writing custom code for each query, the developer can use the JSONPath feature to streamline the process.
Example Workflow
Input JSON
The developer provides a JSON object, such as:
{
"store": {
"book": [
{"category": "fiction", "title": "Book A", "price": 10.99},
{"category": "non-fiction", "title": "Book B", "price": 12.99}
],
"bicycle": {"color": "red", "price": 19.99}
}
}
JSONPath Query
The developer specifies a query to extract all book titles:
$.store.book[*].title
Result
The system processes the query and returns the following result:
["Book A", "Book B"]
Benefits
- Efficiency: The developer quickly extracts the required data without custom logic.
- Flexibility: Queries can be adjusted dynamically for different parts of the JSON.
- Error Handling: Malformed queries or invalid JSON inputs are gracefully managed.
Conclusion
This use case demonstrates how JSONPath functionality simplifies working with structured JSON data, making it a valuable tool for developers.

This seems like a great idea, and very useful. Any insight into why it is not planned?
