What can't you do in Excel?
abc3: I'm surprised that no one else has mentioned EditGrid. For me, the user experience with EditGrid has always been better than the user experience with Google, and EditGrid has always had more and better features as well. See:http://www.editgrid.com/tnc/pkchan/EditGrid_v._GoogleThe thing Excel doesn't do as well as I'd like is Text to Columns, specifically for 13F filings. Many people like to track what major investors are buying and selling and would like to do this directly, from SEC filings, instead of through websites like Gurufocus.For example, here's the Gurufocus page for Seth Klarman:http://www.gurufocus.com/ListGuru.php?GuruName=Seth+KlarmanYou can also find the data for his investment firm, Baupost Group, at SEC Info:http://www.secinfo.com/$/SEC/Filing.asp?T=1ZCS7.t61_1wtClearly, it's possible to automatically get the data from Baupost's freely available SEC filings (http://www.sec.gov/Archives/edgar/data/1061768/0001061768080...) into a spreadsheet. It's just that Excel seems to make it a lot harder than I'd like.
