Searching for Spreadsheets with Google: "Is there anything that Google can't do? This via ResearchBuzz.com, I found out that by using various syntaxes you can find spreadsheets, in all sorts of formats, with Google.
Here's how it works:
filetype:xls is the search string for finding any kind of Excel spreadsheet. For instance, you could type in planning filetype:xls and this is what you would come up with.
ResearchBuzz came up with a few more special ways to mix up the syntax, including this little gem: intitle:gantt filetype:xls site:edu.
Finding spreadsheets is not really my idea of a good time on the Web, but I'll contribute a search query: filetype:xls inurl:budget. My results are predictably full of budgety goodness. "
Well how about that! Why reinvent the wheel?
