🧹 Archive Duplicate Items from Notion Database

This n8n workflow solves the common issue of duplicate entries cluttering Notion databases by automatically pulling all pages, identifying duplicates based on a user-specified property (e.g., URL, title), and archiving the extras while preserving one instance per group. It supports two flexible triggers: a daily schedule for routine maintenance or an on-demand trigger when new pages are added, ensuring proactive data hygiene.

Ideal for users managing links, tasks, notes, or content repositories in Notion, it saves hours of manual cleanup, prevents data bloat, and keeps databases organized. Whether for personal knowledge bases, project trackers, or content calendars, this workflow scales effortlessly for any Notion-heavy setup, reducing errors and improving efficiency.

Setup is straightforward: connect your Notion account, select the database, and configure the duplicate-detection property in the 'Format items properly' Set node using n8n's drag-and-drop. Customize by changing the property, replacing archive with tags/updates, or adjusting the schedule. It's a set-it-and-forget-it solution for tidy Notion management.
