Create an Excel table in a spreadsheet from an external file. Is it possible?
No, it's not possible to do this while using this application, but Excel has a built-in option that allows you to create and add data from external sources. You can find this option in Data tab, then Get External Data group, click Existing Connections.
Besides this option, you also have the possibility to use other pre-defined services and selecting options.
Use the Office Support in order to read more about it since it's a rather complicated procedure: https://support.office.com/en-us/article/Connect-to-Import-external-data-9967afd8-85ee-4df3-aa06-753bcc1a2724
