The short answer is maybe, but you will not change the file date just by opening the file. When you save a file, it will display the date and time when you saved it (as set in your computer date-time settings). Excel will ask you if you want to save the file when you exit (assuming you did not change the default settings). You can choose to leave the file as is (same file date) or save the file (current file date). An exception to this would be determined by your auto save settings on Excel. If you make any changes to the file, Excel might automatically save the file (thus, changing the file date). Additionally, windows may save the last-accessed date. Bottom line, if you want to view an Excel file and not change the date, save the file to a different name as soon as you open it. Then examine the file copy.
That will depend on what you want to do. If you are in Excel saving as a standard Excel file, you don't need to change the file type. It is only if you want to save into a different format, that you would change the File Type. What you change it to, would depend on what you need. You might want to change to a different version of Excel or maybe into a completely different format, such as a text file. If you are working in a different application, saving something to be used in Excel, then again it will depend on what format you actually need.
