Remove duplicates from Google Sheets safely.
Export the relevant sheet as CSV, clean it locally in your browser, and import the reviewed result as a separate sheet. This is a careful file workflow, not a direct Google Sheets integration.
Export one sheet as CSV
In Google Sheets, choose the tab you want to clean and download it as a comma-separated values file. CSV contains cell values, so retain the original spreadsheet for formulas, formatting and other tabs.
Choose what makes a row duplicate
Remove rows only when every exported value matches, or select approved key columns such as customer ID. Avoid treating a similar name or shared email as proof without checking the business context.
Review exact and likely matches
Exact deduplication updates the preview and row count. Fuzzy suggestions show similar values separately and cannot delete rows, giving you a safer list for manual investigation.
Import the result separately
Download the cleaned CSV and import it into a new sheet or spreadsheet. Verify types, identifiers, formulas and downstream references before replacing any working data.
