Convert JSON with a ton of values under each (property? object?) to CSV with many rows is returning all values in one string

I'm trying to use PowerShell to convert a json with the following format:

{"Value1":[89,91,88,71,59],"Value2":[53,58,54,53,58]}

To a CSV with the following format:

Value1,Value2
89,53
91,58
88,54
71,53
59,58

The issue I'm running into is that this code that I've cobbled together

Get-Content 'C:\test\test.json' | ConvertFrom-Json | 
select  @{n='value1';e={-split $_.value1}},
        @{n='value2';e={-split $_.value2}} |
Export-Csv -NoTypeInformation 'C:\test\test.csv'

is making a CSV with the following format:

Value1,Value2
89 91 88 71 59,53 58 54 53 58

Does anybody have any ideas on what I could do here? I'm really new to PowerShell and I'm getting pretty lost. I've read a ton of similar items on here and other sites, but none that exactly fit the issue I'm running into.

Thanks

There might be more sophisticated solutions but at least for this simple example the following snippet works I think:

$Var = '{"Value1":[89,91,88,71,59],"Value2":[53,58,54,53,58]}' | ConvertFrom-Json 

$Var.Value1.Count
for ($i = 0; $i -lt $Var.Value1.Count; $i++) {
    [PSCustomObject]@{
        Value1 = $Var.Value1[$i]
        Value2 = $Var.Value2[$i]
    }
}

The output looks like this:

Value1 Value2
------ ------
    89     53
    91     58
    88     54
    71     53
    59     58
