The source JSON file contains people records that must be converted to CSV. If you follow the steps below, you will learn how to create such a mapping file from scratch. This example is accompanied by a demo mapping file available at the following path: \Altova\MapForce2023\MapForceExamples\Tutorial\ ReadJSON.mfd.
However, in the event that the JSON instance contains additional properties, you can use the technique illustrated in this example. As a rule, you should avoid relying on additional properties and instead define all the properties in your JSON schema. Additional properties refers to data that is present in the JSON instance file even though it is not defined by the schema. You will also learn how to map data from additional properties that might be present in JSON instance files like the one illustrated in this example. This example shows you how to read data from a JSON file and convert it to a comma-separated text file with MapForce.
