For the first option, start with the list of submissions.
This method is useful when you want to sort the submissions, e.g. by the names of the authors, or if you want to filter them, e.g. only display one submission type.
Please go to:
Overview => Submissions & Reviews => List of Submissions
You can use the filters to narrow down the submissions or sort by ID, author's name or title of the submission.
Open the menu "Related Functions" and click on the option "Save abstracts of current page to disk" to save all abstracts directly in a Word file (see image).
