I'm curious about why this just happened. I came across a three year-old question basically asking for library recommendations. The question had been closed for quite some time.
It had two answers. One was accepted with one up vote. That answer only had links to a few offsite libraries.
Here's the now deleted answer:
This are the list of Free excel file creator... Give it a try
ObjC++ wrapper and framework to construct Microsoft Excel
http://sourceforge.net/projects/xlslib/
This is the link of open source project, it may help you-:

I flagged the answer as "not an answer".
The flag was declined but the moderator deleted the whole question.
Why not mark my flag as helpful if the whole question should have been deleted? Wasn't my marking of the poor answer helpful in removing a bad question?
