Extracting JSON values from API responses has always been a time-consuming task for me during workspace development. My previous workflow involved receiving an API response from HTTP Caller, pasting it into VS Code, saving it as JSON, opening a new FME Form Window, adding a JSON Reader, and then changing Schema Scan Mode to JSON Query before selecting a query.

To streamline this process, I created a transformer specifically for parsing JSON strings. This transformer dynamically sets feature attributes based on JSON paths and their corresponding values from a specified attribute of an incoming feature.

The transformer is particularly useful for handling deeply nested JSON structures, making data manipulation within FME workflows more effective and efficient.
