This file could not be translated using the selected file type

Hi techyv guys, I have a problem here with Filemaker Pro, I encountered an error message when I imported a data from Microsoft Excel, you may refer from the image below for better view of my problem.
FileMaker Pro
This file could not be translated using the selected file type.
This process of importing data from excel is not new to me, I been doing this for many time when I received a data from field office, what I did first when I saw the error message is to ask for another copy of the data, when I tried it again, same error message was displayed on my screen. Please help me find ways to import this data, thanks.
