I've this Json, I need to create from this json another json containing the name,and ID of every project in this form name:name value:id in json file...

I've tried somenthing like this..

   $json = Get-Content $file | ConvertFrom-Json 

   ForEach($i in $json.value.id)
    {
      Write-Host "Id: $($i)","name: $($json.value.name)"
    }

Answer 1

• Read the JSON file and convert it using ConvertFrom-Json.
• Select the id and name properties and convert back to json
• Write the newly created json to file

Something like this:

$json = Get-Content -Path 'X:\YourJsonFile.json' | ConvertFrom-Json

$newJson = $json.value | Select-Object id, name | ConvertTo-Json

# output on screen
$newJson

# output to new json file
$newJson | Set-Content -Path 'X:\YourNewJsonFile.json'

Output:

[
    {
        "id":  "12345678-123456-23424-123456ff2",
        "name":  "TestProject"
    },
    {
        "id":  "12345678-123456-23424-123456ff2",
        "name":  "KC-TestAutomation-Framework"
    },
    {
        "id":  "b2345678-123456-23424-12345",
        "name":  "Training"
    }
