Hi Kristina,
I'd suggest you create a Template Task report, grouped by Template, ordered by Template, Template Task Number, filtered to those 100 Templates, with as many columns in the view that are of interest (e.g. Task Name, Duration, Planned Start, Planned End, Predecessors, Assignments, etc.) and then either assess them online (e.g. so you can also show the Gantt view) or export them to Excel for further study.
Regards,
Doug
