Smart Column Cleaner — Help & FAQ
Tools
- De-Duplicate Cells (by Column): select one column → removes/marks duplicates based on mode.
- Clear Duplicates Within Each Row: select 2+ adjacent columns.
- Trim Whitespace: removes leading/trailing spaces.
- Change Case: lowercase / UPPERCASE / Proper Case.
- Remove Non-ASCII: removes emojis and non-ASCII characters.
Duplicate modes
- blank – set duplicate cells to empty.
- highlight – keep values and mark duplicate cells pink.
- remove rows – keep the first occurrence and move later duplicate rows to a new sheet (“Removed by SCC — …”).
Quota & Pro
Free tier allows cleaning up to 300 cells/day. Pro users have no daily limit.
Troubleshooting
- “Select exactly one column” → your selection must be a single column.
- “No duplicates found” → try removing extra spaces first using Trim.
- Connection lost → close and reopen the sidebar.
