I wanted to understand how to use Excel better, and I had some question regarding it. Which exchange site is good for this?
2 Answers
Super User is the appropriate site for general Microsoft Excel questions, including those dealing with built in Excel features, functions, and formulae.
And as suggested by psubsee2003 in this answer:
For help with automation in Excel using VBA, including User-Defined Functions, then Stack Overflow is probably a better resource
I see you already accepted an answer, but just to add to the existing answer, I think the best Stack Exchange site depends on your exact usage.
For general Excel questions, including those dealing with built in Excel features, functions, and formulas, Super User is absolutely the correct site.
But for help with automation with Excel using VBA, including UDF (User Defined Functions), then Stack Overflow is probably a better resource
