I have an array of hash table containing key value pairs, like below :
$myTest = @{};
$test1 = @{
Name = "Food1"
Value = "Sandwich"
}
$test2 = @{
Name = "Food2"
Value = "Salad"
}
$myTest["Food1"] = $test1;
$myTest["Food2"] = $test2
On running the command $myUpdatedTest = $myTest.Values | ConvertTo-Json -Compress
$myUpdatedTest = $myTest.Values | ConvertTo-Json -Compress
gives the value in $myUpdatedTest
--> [{"Value":"Sandwich","Name":"Food1"},{"Value":"Salad","Name":"Food2"}]
And if I have only $test1
added to the $myTest
then the value comes in as {"Value":"Sandwich","Name":"Food1"}
But in the later case I want the value to be inside []
--> [{"Value":"Sandwich","Name":"Food1"}]
is there way to achieve this.
The issue with this is how you are sending the object to the ConvertTo-Json
cmdlet.
I managed to get this working by changing
$myUpdatedTest = $myTest.Values | ConvertTo-Json -Compress
to
$myUpdatedTest = ConvertTo-Json -Compress -InputObject $myTest.Values
This then evaluates the whole $myTest.Values
object as opposed to each value one by one. I hope this makes sense?
Kinda clunky, but this works:
$myTest = @{};
$test1 = @{
Name = "Food1"
Value = "Sandwich"
}
$test2 = @{
Name = "Food2"
Value = "Salad"
}
$myTest["Food1"] = $test1;
$myTest["Food2"] = $test2
if($myTest){
if($myTest.Count -eq 1){
$myUpdatedTest = "[$($myTest.Values | ConvertTo-Json -Compress)]"
}else{
$myUpdatedTest = $myTest.Values | ConvertTo-Json -Compress
}
}
$myUpdatedTest
