I recently upgraded my Excel 2003 to the latest version(Office 2013). I cannot open any of my older versions of Excel workbooks in the new version. Is there any way to do this or do i have to re-create all of the work in new version.
Office 2013 does not open old office files directly from explorer.
To open these files, you have to associate to and convert it into an office 2013 acceptable format first.
Right click on the file that you want to open and select the
Open with... option.
Office 2013 as program for opening the file.
After that, office 2013 will ask you if you want to convert the file to office 2013 standards. Accept this request and convert the file.
After the conversion is done, the old office file will have the new office 2013 layout. Your file will now open.
