Append text file to an existing Excel Table in SharePoint

I want to be able to append data records from an email attachment to an Excel table in SharePoint. My source data is Cognos and it can email Excel (non-table), CSV, XML, HTML date files, but I cannot determine how to append any of these data file types to an existing Excel table in sharePoint.

Re: Append text file to an existing Excel Table in SharePoint

Hi @PBUser,


Which file type is the Attachment file of your received email?


If the file type of the Attachment file of your received email is Excel (non-table), CSV, XML or HTML, I afraid that there is no way to append the data of these files to an existing Excel table in your SharePoint list currently.


We could get the Attachment content from the received email, but the result the Attachment content returned is a binary data. There is no way to analyze binary data within Microsoft Flow currently, if you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:
