Form Duplicates Finder for Forms

Find duplicate form responses by a key question or full-response match

Find duplicate responses in your Google Form in one click — by a key question
you choose (like an email field) or by a full-response match — so you can clean
them up fast.

WHAT IT DOES
• Find by key question: pick any question from a dropdown (e.g. "Email Address")
  to catch responses that share the same answer — perfect for people who
  submitted twice.
• Find by entire response: catch fully identical submissions where every answer
  matches, regardless of item order.
• Clear results: each duplicate group shows the shared key, how many responses
  share it (e.g. 3x), and the exact timestamp of every duplicate.
• Smart matching: keys are normalized (case-insensitive, trimmed) so
  near-identical entries still group together.
• Blank-safe: responses with no answer to the key question are ignored — a
  missing answer isn't a duplicate.

HONEST NOTE ON DELETING
Google Forms gives add-ons no way to delete an individual response (only all at
once), so this add-on identifies duplicates precisely — the key, the count, and
each timestamp — so you can remove the extras by hand in the Responses tab in
seconds. We don't pretend otherwise.
