How to Read a JSON File in PowerShell and Assign Array Elements to New JSON Objects

Working with JSON data in PowerShell can be cumbersome, especially when you need to manipulate array elements and convert them into new structures. In this guide, we are going to address a common question: "How to read a JSON file in PowerShell and assign the array elements to new JSON objects?"

Understanding the Problem

Imagine you have a JSON file with an array of objects, and you want to read each item in that array and create new JSON objects based on the data inside them. Here’s an example of what our JSON file looks like:

You want to extract the buildapp section and convert each block into its own JSON object. This conversion should continue depending on how many items you have in your array.

Expected Output

After processing, you'll want to achieve a structured output that could look like this:

appname = apple

category = fruit

buildapp.workdir1 (including work1's data)

buildapp.workdir2 (including work2's data)

The Solution

To accomplish this in PowerShell, follow these steps:

1. Reading the JSON File

You will need to read the JSON file’s contents and convert it into a PowerShell object.
