Deduplicate Google Sheets by Profile URL & Auto-Update

This n8n workflow automates the cleaning of Google Sheets by removing duplicate entries identified by the profileUrl field. It starts with a manual trigger, retrieves all rows from a specified sheet, processes the data to eliminate duplicates, converts the cleaned dataset into a file format, and then overwrites the original sheet with the deduplicated content. This ensures your datasets remain organized without manual intervention, saving time on repetitive data hygiene tasks.

Key benefits include preventing errors from duplicate leads in CRM systems, maintaining accurate contact lists from scraped or imported data, and streamlining marketing databases. The process is quick, typically completing in seconds even for large datasets, and requires only Google Sheets and Drive credentials setup in n8n.

Ideal use cases: CRM lead deduplication to avoid outreach to the same prospect twice; cleaning email or contact lists with overlapping entries; managing marketing submissions where duplicates arise from multiple sources. Update your spreadsheet ID and sheet name, then execute anytime to keep data pristine.

Setup is straightforward: connect credentials, configure sheet details, and run. No coding needed, making it accessible for non-technical users in marketing and sales teams.
