PowerShell でMailChimp Data データをCSV に落としてみた

標準PowerShell cmdlets を使ってMailChimp テーブルにアクセス。

CData Cmdlets Module for MailChimp は、直感的なMailChimp データ連携を提供する標準cmdlet です。 本記事では、MailChimp Cmdlets を使ったサンプルを提供します。

Creating a Connection to Your MailChimp Data

You can set the APIKey to the key you generate in your account settings, or, instead of providing your APIKey, you can use the OAuth standard to authenticate the application. OAuth can be used to enable other users to access their own data. To authenticate using OAuth, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with MailChimp.

See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

$conn = Connect-MailChimp  -APIKey "$APIKey"

Selecting Data

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

Select-MailChimp -Connection $conn -Table Lists | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myListsData.csv -NoTypeInformation

You will notice that we piped the results from Select-MailChimp 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.

The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.

Deleting Data

The following line deletes any records that match the criteria:

Select-MailChimp -Connection $conn -Table Lists -Where "Contact_Country = US" | Remove-MailChimp

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 MailChimp, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyListsUpdates.csv | %{
  $record = Select-MailChimp -Connection $MailChimp -Table Lists -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-MailChimp -Connection $mailchimp -Table Lists -Columns ("Name","Stats_AvgSubRate") -Values ($_.Name, $_.Stats_AvgSubRate) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-MailChimp -Connection $mailchimp -Table Lists -Columns ("Name","Stats_AvgSubRate") -Values ($_.Name, $_.Stats_AvgSubRate)
  }
}

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!
