Reading WPS Spreadsheet

I am connecting to a report folder containing multiple Excel workbooks of the same layout. I have a user in China who uses WPS Office (WPS spreadsheet is said to be compatibale with Excel) Excel does not have a problem with the file - but Power BI will not recognize it as an Excel file. All the workbooks in the folder process fine if I remove the WPS/Excel workbook. If I re-create the file (copy/paste all values) into an Excel file, the workbook is then recognized by Power BI. I suspect there is something in the XML file structure that Power does not "like".

How can I work around this problem - user in China is a third party organization - so asking them to "upgrade" is not an option. I need to receive and process these files daily.
