RoboHelp does offer some exporting options. But before we "go there", perhaps it would be most useful if you were to tell us what you hope to accomplish by doing this? If we know what the goal is (aside from just wanting topics in Excel) perhaps we can more effectively help you.
The goal is to export to Excel without having to copy/paste and without having to do a bunch of re-formatting. We want to be able to re-use the content in our test scripts for our software with a minimum of re-work.
