Default workbook template for Microsoft Excel
This is a default workbook template for Microsoft Excel. In order to make it the default template once you start Excel, download the file and save it in a folder like:
C:\Users\<user name>\AppData\Roaming\Microsoft\Excel\XLSTART
or
c:\Program Files (x86)\Microsoft Office\Office14\XLSTART (the folder name Program Files (x86) can vary)
If you are using a non-English version of Excel, you will likely need to rename Book.xltx to a file name corresponding to your Excel localization, e.g. Mappe.xltx (Danish)
