Sending Data Between Tables Without Overwriting

To append data to a destination table while preserving existing data:

1. Use the Send table data action to transfer data from your source table to the destination table
2. In the mapping step, double-click each field to map it to existing columns in the destination table
3. Configure the advanced settings:
   • Enable "Map to existing columns"
   • Disable "Auto-extract new columns"

Important Notes

• This approach appends new rows without modifying existing ones
• Clay automatically protects manually entered data in existing columns from being overwritten
• Clay will only auto-map to columns that contain formulas
