Hello!

I'm new to VBA and I need some help for a basic thing:

I developed a macro, "export_data", and I want to launch it when I press a button.
I've created a command button from User Form, but I don't know how to place the action (when I press the button, the macro should be launched), and also, how to add this button in the Excel worksheet, because it's only designed in VBA.

Thanks in advance,
Chris
