Converting Excel 2003 files to 2010

I recently changed from Office 2003 to 2010.  I have thousands of Excel files in the 2003 format.  When I open them now I’m saving them to the 2010 format, then I delete the old file.  This is time consuming, and I’m wondering if there’s a way to convert all files at once.  My Office 2010 is on a new computer, so I did a clean install, not an upgrade.  I’m still using my old computer with Office 2003, and I’d prefer not to upgrade that one to Office 2010.

Hi Greg,

Why convert them?

Excel 2010 will happily work with older Excel files, so just leave them as .xls format.

If / when you ever open a file, you can always re-save as Excel 2010 format (.xlsx) then.

In fact, that way, your Excel 2003 machine(s) can then also access the (unconverted) files too.  You can install an update to Excel 2003 that allows them to read newer files, but if you leave them in .xls format, you don't need to worry about that.

HTH,

Alan.
