Hi @Jim_Liao 

You may want to try adding again the worksheet. 

Use the "Browse for more data" for this purpose.

If you still have an issue with that, I suggest you contact Support team through here:

Login - AppSheet

The error tells you what the problem is:

The file you've specified is not an XLSX file, even though its name ends with .xlsx.

Use data from Excel spreadsheets in Office 365 and SharePoint - AppSheet Help
