Hi James, Have you tried the FlattenJson processor? It covers exactly your scenario, perhaps with some tweaking to field names needed.

I am not that familiar with NiFi JSON processors, and am hoping someone can help me with a requirement to transform and parse incoming json. The biggest challenges for me here are that the keys in my incoming final_results can vary in number, and I need to use actual key names to form my json output results. Here is a dummied up representation of an incoming object: { "bigStructure":{ . . . "final_results": { "Label1": { "color": "red, "temp": "0C" }, "AnotherLabel": { "color": "blue, "temp": "32F" }, . . . "LastLabel": { "color": "black, "temp": "0K" } }, "ID": "12345", "lastUpdated": "20220309" } } Here is what I need to generate as my output object: { "Label1.color": "red", "Label1.temp": "0C", "AnotherLabel.color": "blue", "AnotherLabel.temp": "32F", "LastLabel.color": "black", "LastLabel.temp": "0K", "ID": "12345", "lastUpdated": "20220309" } I gather that this transformation needs to happen because they feed that output structure into a database that expects the data in this format. Can I do this with "out of the box" nifi processors? Any help is much appreciated. Thank you in advance!
