Welcome back everyone! This week we will take another look at some common data types we might encounter in the real world: JSON data.

JSON data is used pretty frequently on the web if you’re hitting APIs. This not only includes external data (twitter, weather, marvel database), but often includes internal data to your company. It’s nice to be able to leverage data from anywhere, and it can be frustrating for people to try to parse JSON data.

Luckily, we have this all built in for you using ConvertFrom-JSON

I’ll get a response from an API online used for testing:

$response = Invoke-WebRequest -Uri '<a href="https://jsonplaceholder.typicode.com/users">https://jsonplaceholder.typicode.com/users</a>' -UseBasicParsing

The response data looks like this:

StatusCode : 200
StatusDescription : OK

And if we check out the “content” property we can see the actual JSON:

This contains 10 fake users. If we want this data to be more usable we can parse the response directly using ConvertFrom-JSON:

$users = $response | ConvertFrom-Json

Now we could do whatever we want with these users

foreach ($user in $users)

{

write-host "$($user.name) has the email: $($user.email)"

}

Leanne Graham has the email: Sincere@april.biz

Ervin Howell has the email: Shanna@melissa.tv

Clementine Bauch has the email: Nathan@yesenia.net

Patricia Lebsack has the email: Julianne.OConner@kory.org

Glenna Reichert has the email: Chaim_McDermott@dana.io

Clementina DuBuque has the email: Rey.Padberg@karina.biz

So there you have it, working with JSON data can be easy once you turn it into PowerShell objects. Hopefully this helps you work with APIs and process data on your PowerShell adventures.
