CopycullFind, highlight, merge or remove duplicate rows in Google Sheets and duplicate responses in Google Forms, with close-match search

Copycull finds duplicate rows in Google Sheets and duplicate responses in Google Forms, shows you every group before anything changes, and then does what you pick: highlight them, label them, copy or move them to a new tab, delete the extra copies, or merge each group into one row.

What you get

• Find duplicates by any columns, with close-match search for typos and word order
• Highlight, label, copy, move, delete, or merge duplicates into one row
• Keep the first, last, most complete, or newest row in each group
• Always previews first, makes a backup tab, and asks before removing anything
• Delete duplicate Google Forms responses so the Summary counts each person once
• Optional automatic cleanup of repeat form submissions
