I have never had to do that. Excel opens up txt files for me with no issues. I do it all the time.
Same here, but Excel will open automatically with a .tdl file extension. .txt opens in Notepad, and you have to manually right click->open with -> Excel (or open Excel, then File-Open, etc).
In my experience it's much more likely to want to read tab-delimited data with Excel than a text editor, but it's no hard and fast rule.
