CSV or other simple import technique?
I have a lot of bibliography info in Word files. If I turned it into a CSV export file from Word, or perhaps a tab-separated file from Excel, would there be any way to get one of these standard formats to import?
CSV and TSV aren't really standards--there is no commonly accepted "spreadsheet format" for bibliographic information, so field ordering might be frustrating. Other software solves this by letting the user select what column corresponds to what field (though this is frustrating if fields are missing and/or there are columns that don't easily map). After solving this, it is difficult to say what delimiter should be used to separate individual contributors (since ALL contributors are likely to be listed in a single column (if they are already split by columns, then not all records would have the same number & this solution of breaking a field into multiple columns is limited to only a single field) and to the parts of an author's name. Thus, it isn't as "simple" as it seems.
While this edge case is something worth addressing sometime, I think that users can take advantage of cb2bib or other programs to export their bibliographies into a format that zotero and other programs can already import.

the problem is really that anything related to CSV/Excel import is a hack. As noksagt points out, CSV isn't a bibliographic standard - so each solution depends on what information the users has formatted in what way in her/his table.
Generally the documentation is a wiki, so you should feel free to add to it. http://www.zotero.org/support/dev/documentation
That said, I'm not sure if import from tables isn't a case that involves so many ideosyncracies that it's better suited for an external webpage or blog - what I'm worried about is people coming here to complain that "Zotero's" import from CSV doesn't work.

which includes cb2bib as one of many options.
