File extension change from xls to xlsm
Hello,
Validation team added a new revision of a file which originally had the .xls extension.
Now, revision 1.6 has the same name but extension .xlsm.
The problem is that the revisions with extension .xls (1.1 to 1.4) cannot be opened anymore.
Any hints on how to solve this?
Thank you
Cristina
