I have several spreadsheets that were created in MS Excel 2003. I had them marked as read only. When I used MS Excel to open these files, I was able to make changes to the cells then print the sheet. I did not want to save the changes. Now when I open these files with Open Office, I cannot make changes as the file is read only. How can I make these changes without allowing the changes to be saved, but just print the changed sheet? I do not want to use MS Excel any more.
