Sorting PSCustomObject by Changeset Number in PowerShell

PowerShell is an incredibly powerful tool for managing and automating tasks, especially in a Windows environment. One common challenge users face, particularly when accessing data via REST APIs, is sorting complex objects like PSCustomObject. In this guide, we’ll explore how to sort a PSCustomObject containing an array of changesets by their identifier—also known as the changeset number.

The Challenge: Sorting an Array of Changesets

When working with the Azure REST API, you may retrieve a list of changesets tied to specific build IDs. These changesets often come wrapped in a PSCustomObject that contains an array of details for each changeset. Here’s a simplified view of the structure you might be dealing with:

PSCustomObject representing the changesets

Each object may contain an array (Object[]) as a property called value

Each value item is another PSCustomObject which you want to sort by its id

You may attempt to sort the changes using the Sort-Object cmdlet; however, many users find that it does not change the order as expected. The challenge becomes clear: how do you successfully sort a nested property within these objects?

The Solution: Using Select-Object and Sort-Object

To effectively sort the changeset objects based on their id, you can utilize a combination of Select-Object and Sort-Object. Here’s how it works in a step-by-step approach:

Step 1: Expand the Value Property

You need to first extract the value property from the $changeset object. This is where your changeset details reside. To do this, you can use the Select-Object -ExpandProperty cmdlet:

This command will return just the array of changeset objects without the encompassing PSCustomObject.

Step 2: Sort by the ID Property

Next, you need to sort these extracted objects by their id. You can accomplish this with the Sort-Object cmdlet as follows:

Resulting Output

By running the above command, you will get a sorted list of changesets, organized in ascending order based on their id. This is exactly what you want if your goal is to review changes orderly.

Use this sorted list for further processing, analysis, or reporting as required.

Conclusion

Sorting a PSCustomObject in PowerShell can be straightforward once you know the correct cmdlets to use. By utilizing Select-Object to expand your nested properties and Sort-Object for ordering them, you can efficiently manage your data. Remember, understanding the structure of the objects you’re working with is key to successfully manipulating them in PowerShell.

If you follow the outlined steps, you should be able to tackle similar sorting challenges in the future with confidence. Happy scripting!
