title: Cannot convert excel to csv : Azure Synapse Analytics
body: <p>I want to convert Excel to CVS in Azure Synapse Analytics but I got an error.
  The error message is &quot;Invalid excel header with empty value&quot;.
  The Excel file I want to convert looks like this (created for the question) and I need to remove the blank column A when converting to csv.
  I have never used ADF before so I don't know.
  Can someone please tell me how to do this?
  Any help would be appreciated.
