I would like to be able to export answers in .xls.
.txt export is useful, but .xls export should be better because it would permitt to elaborate personal statistics and spreadsheets!

Sometimes having a tab is an easier delimiter to deal with than a comma, since with commas you need to quote the output if it has a comma within the text, e.g. address2 might need to be "Washington, DC".

Having the option to set the delimiter would be the most flexible, since then people could choose | or tab or whatever they wanted. So it could be similar to Answers (immediately above it) where instead of "CSV Format" it could say "Delimited Format", then the boxes underneath could say "Comma, Tab, Other". And I guess there could be a checkbox with the option of quoting the strings as well.

I'm almost done coding this for my local copy, which I can check into a github repository if that will help.

I am looking for surveys that other people have created that I might import into my system. It does not necessarily make sense to always reinvent the wheel. There are many applications of surveys where the questions will be quite similar if not the same. It would be very educational and a huge labor saver as well as enhance the LimeSurvey user community diversity and cohesiveness.
