title: Powershell Import-Csv error "The member X is already present"
body: <p>I'm at my wits' end and could use an assist from this community :)</p>
  <p>I'm trying to import a csv file in to powershell using the Import-Csv module. Here is my code:</p>
  <pre><code>Import-Csv -Path &quot;X:\SourceData\Filename.csv&quot;
  </code></pre>
  <p>This returns the following error:</p>
  <pre><code>Import-Csv : The member &quot;3140.72&quot; is already present.
  At line:1 char:1
  + Import-Csv -Path &quot;X:\SourceData\Filename.csv. ...
  + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      + CategoryInfo          : NotSpecified: (:) [Import-Csv], ExtendedTypeSystemException
      + FullyQualifiedErrorId : AlreadyPresentPSMemberInfoInternalCollectionAdd,Microsoft.PowerShell.Commands.ImportCsvCommand
  </code></pre>
  <p>Doing some light review of the error, the usual culprit is a duplicate column header.  I've verified that I don't have duplicate column headers so I've eliminated that as a possible root cause.</p>
  <p>I then moved to researching the &quot;3140.72&quot; that the error was reporting.  The csv file has about 500 rows and on the 150th row, I see 2 columns with the value &quot;3140.72&quot;. This is not in the 'header' and I have other rows where columns do have matching values.</p>
  <p>Any help would be appreciated!</p>
