Accessing JSON in PowerShell: Simple Notation for Easy Data Extraction

Working with JSON data in PowerShell can initially feel overwhelming, especially if you’re new to the scripting language. Many developers, especially those coming from backgrounds in languages like Python, often find themselves perplexed when tasked with running a webhook that sends a JSON file. If you’re trying to access specific values from a known JSON schema without excessive looping, you’re in the right place!

The Challenge: Working with a JSON Structure

The JSON file you are working with has a defined structure but may seem daunting at first glance. Here’s a condensed version of your JSON schema for reference:

In this guide, we’ll walk through how to access specific values like the item name and vendor directly from the JSON data using PowerShell. You no longer need to clutter your code with complex looping; let’s simplify this process!

Solution: Simple Notation for Accessing Values

Step 1: Read the JSON File

First, we need to load the JSON data into a variable. The Get-Content cmdlet fetches the JSON content, and then we convert it from JSON format using ConvertFrom-Json. Here's how you do it:
