How to Correctly Include an Empty Array in a JSON Object Using PowerShell

When working with JSON in PowerShell, you may often encounter scenarios where you need to include an empty array in your JSON object. Understanding how to correctly achieve this can help prevent errors and ensure your JSON is structured as expected.

Including an Empty Array

In PowerShell, constructing a JSON object is commonly done using the ConvertTo-JSON cmdlet. Below is an example demonstrating how to include an empty array in a JSON object:

In this example:

Defining the Empty Array: We start by declaring an empty array $emptyArray using @().

Creating the Hashtable: Next, a hashtable $jsonObject containing the JSON structure is created, which includes a property Items set to the empty array.

Convert to JSON: Finally, the hashtable is piped to the ConvertTo-JSON cmdlet to convert it to a JSON-formatted string.

The resulting JSON will look like this:
