There's a lot of information here which can be very useful to provide depth to waterdeep but it is very difficult to search through and would currently only be useful between sessions as it is not currently viable for quick look ups.
Some tabs have strange names going from the obvious "Nobles" to the less obvious"CF".
Information isn't always clear with some cells overflowing while others have cut off the text making the tables difficult to read and understand.
There's no easy way to look up information on the fly though hopefully this will be rectified with the generators due in the updates.
I will check back and re-review if the formatting becomes clearer in a future update.
