Hi Koketso,

Is there a way to map xml tags to controls like Checkboxes,Comboboxes in
excel. I want to extract the data into xml.

Not directly, but you can set the controls' linked cell so it writes its
values to a cell, then map that cell to an xml tag.

Another thing is I have this huge project where I have to convert an online
wb app into an offline excel app. Are there any black spots i need to be
aware of?

I guess that depends on the design of the web app. If it uses lots of complex
web services, you might struggle to consume them through the Excel web
services toolkit.
