Yes — WipeAway can clear the date range containing duplicates so you can re-import from a single, clean source file.
Duplicate events from calendar imports are a common problem. If you ran a calendar import twice, or if a migration created duplicates, WipeAway can clear the affected date range in a single operation. You can then re-import from the correct, single-source ICS file to restore the clean version of your calendar data.
