I have a deeply nested JSON file that I have imported using Power Query into Excel Microsoft 365 using
Data>Get Data>From File>From JSON

It loads into a [Record]

I would like to access and process this loaded object using Python-in-Excel.

I have a manual workaround of loading the json as a single string into a single cell and then processing. This works but using queries to first load the file would give more control and circumvent 32K character limits for single cells.
