Problem with merging 2 JSON Files in Powershell

Question

I have to combine following 2 JSON files because the API which i use has a limit of 1000.

js1.json:

{
      "total":  1311,
      "limit":  1000,
      "offset":  0,
      "data":  [
          // 1000 Users
         ]
}

js2.json:

{
      "total":  1311,
      "limit":  1000,
      "offset":  1000,
      "data":  [
          // 311 Users
         ]
}

What i need:

{
      "data":  [
          // All 1311 Users
         ]
}

I have seen a few posts where it is written you could just add the JSON files together. But in the end I always get this:

Current PS Code:

 $js1 = Invoke-RestMethod 'API Request with offset 0' -Method 'GET' -Headers $headers -Body $body | ConvertTo-Json
 $js2 = Invoke-RestMethod 'API Reuqest with offset 1000' -Method 'GET' -Headers $headers -Body $body | ConvertTo-Json

 $js1 + $js2 | Out-File -FilePath .\cloudUsers.json 

Answer 1

What you can do if you only want the content of the data field then you can extract it to a PSObject and merge them and convert it back to JSON if that is the format you want.

$json1 = (Get-Content .\js1.json | ConvertFrom-Json)
$json2 = (Get-Content .\js2.json | ConvertFrom-Json)


$data = $json1.data + $Json2.data

$data | ConvertTo-Json

Answer 2

If you just want to combine the data values and create a new JSON with a data property, you can do the following:

$js1 = Get-Content js1.json | ConvertFrom-Json
$js2 = Get-Content js2.json | ConvertFrom-Json

[pscustomobject]@{data = $js1.data + $js2.data} | ConvertTo-Json

---

If you want to maintain the original JSON schema, you can update the properties accordingly:

$js1 = Get-Content js1.json | ConvertFrom-Json
$js2 = Get-Content js2.json | ConvertFrom-Json

$js1.limit = $js1.total
$js1.data += $js2.data
$js1 | ConvertTo-Json
