Windows 10: Can't save spreadsheets in .xlsx format

I am still using the old Office XP (2002) software. My Windows 10 pc has the 'Compatability Pack for the 2007 Office system' installed. Looking in Default Programs, .xlsx is associated with 'Microsoft Open XML Converter'. when trying to save a spreadsheet, the Excel 2007 Workbook ".xlsx" is not listed under File Name. Only Excel Workbook ".xls" is listed. This is working fine on my Windows 10 laptop.
Thanks for any help.

Unable to open Excel for Mac spreadsheets on my HTC HD2

Hi Susan,

Have you tried saving the Excel spreadsheet in a different format? Instead of saving as XLSX, try saving in the older "Excel 97-2004 Workbook (.xls)" format. The steps below explain how to save the document in a different format:

• Create a file, or open the file that you want to save.
• On the File menu, click Save As.
• In the Save As box, type a name for the file.
• On the Format drop-down menu, choose Excel 97-2004 Workbook (.xls).

While you're trying that, I'm going to move your thread into the Windows Phone forums and see if anyone there can help us out. I'm not quite sure what formats WinMo 6.5 supports and there aren't too many things we can try on the Excel
side.

Let me know if changing the format helps!

Hello Donald,

.XLSX is a file extension for an open XML spreadsheet used by Microsoft Excel. For us to better assist you, we'd like to know the following:

• Confirm which build is currently installed on your device. To check, follow the steps below:

• Press Windows key + R, then type in winver.
• Click OK.

• Is Microsoft Excel installed on your computer? If yes, which version of Microsoft Excel are you using?
• Are you getting any error messages when opening the .xlsx files?
• Did you create the said file or was it downloaded from a certain source?

We look forward to your response.
