I recall there is some way to extract the list of items, actors etc from the construction set into a text file which I think can then go into an excel.
File >> Export >> Form Component Data for all non-World Forms
Hm. Thanks but that gives just a garbled single file.
I seem to recall that you had to do each category one by one but the result was a nice file with all the info as in the count, description etc in columns which was quite convinient for excelizing.
