Combining Nested Json using PowerShell - json

Question

I have the following Json script:
{
"merchant_info": {
"email": "merchant#example.com",
"first_name": "David",
"last_name": "Larusso",
"business_name": "Mitchell & Murray",
"phone": {
"country_code": "001",
"national_number": "4085551234"
},
"address": {
"line1": "1234 First Street",
"city": "Anytown",
"state": "CA",
"postal_code": "98765",
"country_code": "US"
}
},
"billing_info": [{
"email": "bill-me#example.com",
"first_name": "Stephanie",
"last_name": "Meyers"
}
],
"shipping_info": {
"first_name": "Stephanie",
"last_name": "Meyers",
"address": {
"line1": "1234 Main Street",
"city": "Anytown",
"state": "CA",
"postal_code": "98765",
"country_code": "US"
}
},
"items": [{
"name": "Zoom System wireless headphones",
"quantity": 2,
"unit_price": {
"currency": "USD",
"value": "120"
},
"tax": {
"name": "Tax",
"percent": 8
}
}, {
"name": "Bluetooth speaker",
"quantity": 1,
"unit_price": {
"currency": "USD",
"value": "145"
},
"tax": {
"name": "Tax",
"percent": 8
}
}
],
"discount": {
"percent": 1
},
"shipping_cost": {
"amount": {
"currency": "USD",
"value": "10"
}
},
"note": "Thank you for your business.",
"terms": "No refunds after 30 days."
}
And I want to use PowerShell to get the following Record and export it to CSV:
So far I created the following Script:
$JsonFile = "C:\Users\me\Documents\myfile.json"
$OutputFile = "C:\Users\me\Documents\newtext.csv"
Get-Content -Path $OutputFile
$json = ConvertFrom-Json (Get-Content $JsonFile -Raw)
$json.merchant_info | Select "first_name","last_name",#{Label = "phone"; Expression = {$_.phone.national_number}} |
Export-Csv $OutputFile -NoTypeInformation
I am able to bring values from (Merchant_info, Shipping_info, item) separetely but how do I bring it all in combined like in my screen shot above.

Answer 1

but how do I bring it all in combined like in my screen shot above.
We can only guess; assuming this entire json block is one order, with one merchant and one customer, but multiple items, then each row is an item. So start with that as the input:
Create an output record (PSCustomObject) with the repeated data, and then the individual item data:
$json.items | ForEach-Object {
[PSCustomObject]#{
MerchantInfoFirstName = $json.merchant_info.first_name
MerchantInfoLastName = $json.merchant_info.last_name
MerchantInfoPhoneNumber = $json.merchant_info.phone.national_number
ShippingInfoFirstName = $json.shipping_info.first_name
ShippingInfoLastName = $json.shipping_info.last_name
ItemName = $_.name
ItemQuantity = $_.quantity
}
} | Export-Csv ... etc.
