Hello Jason Zand,
There is an existing HTML report for traceability in the ALM solution. It's called <ALM_Prefix>Document Matrix, although <ALM_Prefix>Document Traces might actually be a better starting point, depending on what you are intending to do.
As an early version of it, you could output the results as a .csv file instead of as HTML, which would make it very easy to import into Excel. That would probably be a reasonable format to get to Excel. In theory, you could probably export it to .xslx, but that would likely take additional post-processing after exporting from Integrity. Certainly, I can't think of any easy way to do it.
If I was forced to hack something to generate a final .xslx, I'd probably use something like this, and modify the script to do the conversion using existing tools, then email the completed report to the requesting user, if I could get the user's email address from the report output.
Regards,
Kael
