Remove an attribute from the JSON object in powershell - json

Question

I have following JSON and I would like to remove streets from the JSON object under Address which is an array. I am trying to do this in powershell
{
"Customer": [
{
"id": "123"
}
],
"Nationality": [
{
"name": "US",
"id": "456"
}
],
"address": [
{
"$type": "Home",
"name": "Houston",
"streets": [
{
"name": "Union",
"postalCode": "10",
}
]
},
{
"$type": "Office",
"name": "Hawai",
"streets": [
{
"name": "Rock",
"postalCode": "11",
}
]
}
],
"address": [
{
"$type": "Home1",
"name": "Houston",
"streets": [
{
"name": "Union1",
"postalCode": "14",
}
]
},
{
"$type": "Office1",
"name": "Hawaii1",
"streets": [
{
"name": "Rock1",
"postalCode": "15",
}
]
}
],
}
I would like to remove streets from the JSON object and here is my powershell script but it is not working! I am trying to convert JSON into object and then loop over properties to remove those.
$FileContent = Get-Content -Path "Test.json" -Raw | ConvertFrom-Json
foreach ($content in $FileContent) {
#Write-Host $content.address
$content.address = $content.address | Select-Object * -ExcludeProperty streets
}
$FileContent | ConvertTo-Json -Depth 100 | Out-File "Test.json" -Force

When you use ConvertFrom-Json it will automatically convert things to objects for you. Once they're objects you can use Select-Object to specify what properties you want to include in the pipeline, with which you can just set $FileContent.address (an array of objects) to equal itself, excluding the streets property from each object in the array.
$FileContent = Get-Content -Path "Test.json" -Raw | ConvertFrom-Json
$FileContent.address = $FileContent.address | Select-Object * -ExcludeProperty streets
$FileContent | ConvertTo-Json
