>Whenever I export a file from VFP 9 application (either using EXPORT TO or Createobject("Excel.Application")) and then open the resulting Excel file, I get the message (as shown in the attached image). Then, when I click on Yes (that is to open it anyway), I don't seem to see any problems with the Excel file content?

I believe you'll see this is you EXPORT with TYPE XLS. Similarly, make sure you're choosing an appropriate format when you save the file via Automation. There's a parameter for SaveAs that lets you specify the format you want. If you're creating an XLSX file, give it that extension.
