What is clean data in Google Sheets?
Clean Data is a data cleanup or sheet operation in Google Sheets: trimming text, splitting columns, removing duplicates, or fixing separators. Cleanup steps usually happen before analysis formulas run.
When to use it
Use cleanup tools when imported data has extra spaces, mixed types, or duplicate rows.
When to skip it
Skip one-off cleanup when the source system can export clean columns in the first place.

Duplicating inside a workbook means copying a sheet tab or repeating row data for another entry. Right-click a tab and choose Duplicate to clone an entire sheet with formulas adjusted for the new tab name.
