Reading and Writing JSON Files in Microsoft Fabric

Tom Martens performs two of the three R’s:

JSON is a straightforward, text-based data-interchange format fully independent of any programming language. This simplicity is why JSON documents have become so widespread.

Often the result of querying a REST API is returned as a JSON document, but this is not the only use case why I consider it important to get familiar with reading from and writing to a JSON file. I think a JSON document is ideal for ingesting values into a Python script or any code, values that are helpful to control the logic and behavior of the script. But of course, it’s also easy to store the value of a variable inside the JSON document, where this value will be used when the script is running again.

Click through for some Python code to perform these operations. There are about a dozen other methods you can use as well, but this is one of the best.
