Dedupe automatically detects and removes duplicate rows in your table based on a selected column. Once turned on, this setting cannot be changed while the table is running. Note that rows with blank cells or values over 200 characters in the selected column will not be deleted.

1. Click the "Dedupe" toggle in the toolbar to open the Auto-dedupe rows popup.
2. Select the column to dedupe by from the "Dedupe via column" dropdown.
3. Choose a duplicate handling strategy from the "Duplicate handling" dropdown:
4. • Keep oldest — When a new row matches an existing one, the duplicate is removed and only the original row is kept.
   • Keep newest — When a duplicate is found, the old row is removed and the new one replaces it. All enrichment processes run only on the new row.
5. Click "Turn on" to activate. Once active, click "Turn off" from the same panel to disable it.
