In regards to PowerShell 5.1 (this is so much easier in PowerShell 7)...
Operating off the assumption that we have a file named jsonConfigFile.json with the following content from your post:
{
"Stuffs": [
{
"Name": "Darts",
"Type": "Fun Stuff"
},
{
"Name": "Clean Toilet",
"Type": "Boring Stuff"
}
]
}
This will create an ordered hashtable from a JSON file to help make retrieval easier:
$json = [ordered]@{}
(Get-Content "jsonConfigFile.json" -Raw | ConvertFrom-Json).PSObject.Properties |
ForEach-Object { $json[$_.Name] = $_.Value }
$json.Stuffs will list a nice hashtable, but it gets a little more complicated from here. Say you want the Type key's value associated with the Clean Toilet key, you would retrieve it like this:
$json.Stuffs.Where({$_.Name -eq "Clean Toilet"}).Type
It's a pain in the ass, but if your goal is to use JSON on a barebones Windows 10 installation, this is the best way to do it as far as I've found.
