How to open and work with (dot) Nessus 5 Reports in Excel 2010


I have been working to find a functional way to quickly move from a completed Nessus scan into excel without a lot of trouble. The goal of bringing the files into Nessus is to make the data more usable and more report friendly. I wanted to avoid messing with transforming the original XML data into csv or even digging through the XML data to chop parts out.

All Nessus scan files are comprised of XML data. You can open and edit these files easily in just about any text editor. I do not recommend using notepad as it will typically bunch everything together and be hard to work with. I like to use Notepad++. If you do not have it installed already you can find it here:
