What it does
An n8n workflow that downloads a CSV file from a web address, converts it to JSON and writes the rows into a Google Sheet. It builds a unique key from the country code and year week, keeps only the records you filter for, and updates matching rows instead of adding duplicates.
Use cases
- 01Refresh a shared sheet from a CSV published on the web
- 02Update existing rows without creating duplicates
- 03Filter a dataset before it reaches the sheet
