There is an add-on which might offer the functions you want and it does not require any exporting/importing of data to a third-party application or a spreadsheet.

I used it only briefly but it seems to work well. It isn't like looking at your own logged-in character or inspecting another player's character with the game's own UI but the data is all there. You have to log in a character and open all of the associated windows, such as Shared Storage and Vault and the Reputation panel, in order for the data to be loaded into the add-on for viewing while you're logged in to some other character.
