Get values from json file in string with separators - json

Question

I have a json file with following format:
{
"total_count": 57,
"incomplete_results": false,
"items": [
{
"id": 123456,
"node_id": "dfghdfjfgjftgjhtfyjh",
"name": "Firstrepo",
"full_name": "MyOrganization/Firstrepo",
[SKIP]
},
{
"id": 4756758,
"node_id": "dtghtfjgjyuj",
"name": "Secondrepo",
"full_name": "MyOrganization/Secondrepo",
[SKIP]
},
{
"id": 568578567,
"node_id": "dsgdfghftghtfyjtyj",
"name": "Anotherrepo",
"full_name": "MyOrganization/Anotherrepo",
[SKIP]
},
{
"id": 58567856,
"node_id": "sjdhfbgsdjfgjsdfjjs",
"name": "Somerepo",
"full_name": "MyOrganization/Somerepo",
[SKIP]
},
How can I get values of repositories and write them in variable or file in csv format. Like:
Firstrepo,Secondrepo,Anotherrepo,Somerepo
Script to get values:
CONFIG Get-list of repos from Github
$GithubAPIURL = "https://api.github.com"
$Suffix = "/search/repositories"
$Additions = "?q=org:MYORG:SEARCH&page=1&per_page=100"
$GithubAPIToken = "&access_token=MYTOKEN"
PROCESS
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$variable = ((Invoke-Webrequest $GithubAPIURL$Suffix$Additions$GithubAPIToken).content | ConvertFrom-Json)
$jsonfile = "c:\a\test.json"
$variable | ConvertTo-Json | Out-File $jsonfile -Encoding UTF8
Get-List of names
$Reponames = (Get-Content $jsonfile -Encoding UTF8 | ConvertFrom-Json)

Answer 1

To get the Names of the Repository use:
(Get-Content $jsonfile -Encoding UTF8 | ConvertFrom-Json).items.name
To convert it to a .csv file:
(Get-Content $jsonfile -Encoding UTF8 | ConvertFrom-Json).items | ConvertTo-Csv -Delimiter ';' -NoTypeInformation | Out-File $csvFilePath
