Sheetgo offers a data processor to ensure you always transfer unique values.
Setting up duplicate removal
All you need to do is set up a regular automation with a Duplicate removal data processor.
Let's go over the steps:
Create a new automation.
Select the source of your data.
Choose the Remove duplicates data processor.
Select the Reference column to look for repeated values. If duplicates are found, only one row with repeated values in that column will be kept. Priority order determines whether the processor keeps the first or last occurrence.
Select a destination where you want to receive the data.
