Hyperglance can export the inventory to Comma-Separated-Values (CSV) format. Which is suitable for loading into software tools such as Microsoft Excel.
First, configure the diagram view how you would like it by applying any filters you wish (e.g. group isolation).
It doesn't matter whether groups are expanded or collapsed - Everything in the current view will be exported even if within a collapsed group.
Then, from the top-right corner of the screen, select the 'Export' icon and choose 'Export to CSV' from the menu:
Your generated CSV file should appear as a download momentarily.
