Even Excel 2003 with the extension installed has problems opening these files, however renamed to xlsx they can be opened correctly. I can also open these files with 7Zip, which leads me to believe that the files are ok, just incorrectly named.
The error message I get is "Error on reading record * 102, F6F7 Offs: 0000059F Bad Record In File"
So I'm trying to help the import by setting:
Code: Select all
ExcelFile.Version := xvExcel2007;
