What it does
This n8n workflow reads every CSV file in a folder and removes duplicate rows by user name. It keeps only the rows marked as subscribed and sorts them by subscription date. It then appends new rows to a Google Sheets document and updates the rows that already exist.
Use cases
- 01Merge several CSV exports into one sheet
- 02Keep subscriber lists free of duplicate names
- 03Update existing rows instead of adding copies
