How to pipe GitHub Data to CSV in PowerShell

The CData Cmdlets Module for GitHub is a standard PowerShell module offering straightforward integration with GitHub. Below, you will find examples of using our GitHub Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your GitHub Data

GitHub uses the OAuth 2 authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started chapter of the CData help documentation for an authentication guide.

$conn = Connect-GitHub  -OAuthClientId "$OAuthClientId" -OAuthClientSecret "$OAuthClientSecret" -CallbackURL "$CallbackURL"

Selecting Data

Follow the steps below to retrieve data from the Users table and pipe the result into to a CSV file:

Select-GitHub -Connection $conn -Table Users | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myUsersData.csv -NoTypeInformation

You will notice that we piped the results from Select-GitHub into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

Deleting Data

The following line deletes any records that match the criteria:

Select-GitHub -Connection $conn -Table Users -Where "UserLogin = mojombo" | Remove-GitHub

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into GitHub, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyUsersUpdates.csv | %{
  $record = Select-GitHub -Connection $GitHub -Table Users -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-GitHub -Connection $github -Table Users -Columns ("Name","Email") -Values ($_.Name, $_.Email) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-GitHub -Connection $github -Table Users -Columns ("Name","Email") -Values ($_.Name, $_.Email)
  }
}

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
