To open a file as read only, just follow the steps

• Select your file through the file open box (CTRL+O)
• Now at the bottom you may notice an ARROW BOX next to the OPEN button (in fact, it is a drop down box)
• Click the arrow and select OPEN READ ONLY.
• Now you could be having a read only version of the original file.

You could use this option if you just want to view the file and don't want to make any changes. You should select a file before using this option. If you navigated to the folder but haven't selected the file, the OPEN READ ONLY option would not be highlighted (The option would show up but you cannot click on it. It would be disabled)

To open a copy of a file, just follow the steps and instead of OPEN READ ONLY use the OPEN AS COPY option. The step by step instructions are:

• Select your file through the file open box (CTRL+O)
• Now at the bottom you may notice an ARROW BOX next to the OPEN button (in fact, it is a drop down box)
• Click the arrow and select OPEN AS COPY.
• Now you could be having a copy of the original version of the file.

Note:
If you open a copy of the file, then a duplicate version of the same file is created in the directory of the original file. See more here

You can also use the OPEN AND REPAIR option if you suspect your file is corrupted. Excel may present you with a message box which you may utilise.
