Olá Richard, Exporting to a spreadsheet has been one of the facilities of UFT, I use most, for preparing reasearch.
1. For researching at the National Military Archives, I use a spreadsheet grouped with all people who has a tag "military". The fiels I choose are - Name, free date, sort date/event date ( for sorting purposes) and born/living place and parents name.
2. For researching other archives I use a variant of 1. I use tags (for example for religious people) or locality for vital records.
These are the basics, but the variants are endless...
