There are two options: You can (1) create them as excel tables, e.g. to do some sorting or to create some stats for a presentation, or (2) as part of a document (DOC item), to have electronic signatures.

Excel tables (1)

You can make a report which produces an excel. Just select the REPORT called "Project Export to Excel" and use the risks you need to analyse as input.

Note: Depending of the project you might need to create the excel REPORT template first: to do so select a REPORT folder and click on "create report template" and create it using the drop down.

Look at the video on how to do this:

Word/PDF Documents (2)

You can insert a section "risk analysis" into any DOC item. In the section's options remove all the parts you don't want.
