Convert PowerShell JSON to a CSV file - json

Question

I have not used PowerShell much. I have an API request which returns JSON that I need to turn into a CSV or xlsx file.
$output = Get-SurveyParticipents `
-url "https://orxsurveys.limequery.com/admin/remotecontrol" `
-session $sessionKey `
-id "5133965" `
-start "0" `
-limit "2" `
-unused $False `
-attributes ["completed", "usesleft"]
Write-Host($output | ConvertTo-Json)
{
"id": 1,
"result": [
{
"tid": "6",
"token": "35ddmyQTlNpzLat",
"participant_info": "#{firstname=Hsdfng; lastname=Gsdfh; email=gosdfdsfz.com}"
},
{
"tid": "7",
"token": "nQ_S838LjYT4mR6",
"participant_info": "#{firstname=Ofdlga; lastname=Yadfdfa; email=olsdfdsfivska#axsdfdsfnce.com}"
}
],
"error": null
}
The participant_info doesn't look like a normal JSON structure.
Also I am unsure how to turn this JSON into a CSV. Something like:
$output | ConvertTo-Json | Export-Csv -Path "c:\Scripts"

You don't need to do both Export-Csv and ConvertTo-Json. Export-Csv will convert a stream of powershell objects into a file containing CSV records.
Assuming the objects in the "results" array in your json output are what you want, you might try something like:
$output.result | Export-Csv -NoTypeInformation foo.csv
You are correct to say that participant_info is not Json. You'll have to process this yourself. ConvertFrom-StringData might be helpful.
