whatever your question is, wolfram alpha will be able to answer it. the self-declared google-killer will go live soon — in the meantime, you might want to read stephen wolfram's introductory blog post, or check out some example queries featured in this screencast. sure looks promising...

mostly a note to myself, but this maybe comes in useful to others:
- export excel table as tab-separated values
- open in any text editor with regular expression support
- replace \t with | (inserts column boundaries)
- replace ^(.*)$ with |\1| (pre-/appends boundaries for first/last column)
- replace || with | | (inserts a space for empty columns; run again if the previous run produced new pairs)
