Clean a List in Google Sheets

Clean a List in Google Sheets in two minutes

Plenty of lists live and die in a Google Sheet that no one ever verifies — a tab that quietly accumulates dead addresses and duplicate rows. A quick export-clean-paste round-trip through BounceBlock turns that working sheet into a verified list without changing how you work.

The problem

What's hiding in your list

Sheets-based lists are edited by hand over time, so typos, duplicates and stale entries pile up unnoticed.

A spreadsheet has no way to tell a live address from a dead one — it only stores the text you typed.

Lists shared across a team in a Sheet drift out of sync, with the same contact entered slightly differently in multiple rows.
