I use MS Excel at the office. I have to change many contents in Excel and compare them with the old versions of the same file. For this purpose I used to save the file by a different name.
I then remembered that MS Office 2003 has version tracking, so I wanted to use it, but I have Office 2007. It seems absent. I have many versions of the same file and it’s hard to remember the contents.
Where can I find some software or a trick that will help me compare versions of the same Excel file in Office 2007?
