Excel file not opening in powerBI

[goalie_]

Has anyone encountered the error below when trying to read in an excel file into powerBI?

Error:

Unable to connect

We encountered an error while trying to connect.

Details: "The input couldn't be recognized as a valid Excel document."

However the file can be opened in excel without a problem and has a .xlsx extension. Any help or what to check?
Other files of the same format seem to work but some do not. I'm unable to share the files unfortunately.

Convert Excel file into csv and try.

Hi @goalie_ ,

One of the reason could be that the data that you are importing to PBI is not in excel table. Select the rows and columns from the sheet that you want to import >> Insert Table in excel and try importing it should be able to read the data then. 

You can make a try and tell me if it works. Looking forward to your reply.

Best Regards,
Henry
