How it works

This template finds and removes duplicate contacts in Odoo based on email address. Within each group of duplicates, the record with a name is kept. If all records in a group have a name, the first one is kept. The rest are deleted automatically — no manual review needed.

Read all contacts from Odoo

The Putki Odoo Input plugin reads all contacts from res.partner, fetching their id, name and email. Only contacts with an email address are processed — those without are filtered out immediately.

Flag and sort

Each contact gets a has_name flag (1 = has a name, 0 = empty). The full dataset is then sorted by email and by this flag — so within each duplicate group, the named contact always rises to the top.

Identify duplicates

A JavaScript step tracks the email from the previous row and assigns a row number per group. Row 1 is the record to keep. Any row with a number greater than 1 is a duplicate.

Delete duplicates

The Putki Odoo Delete plugin removes all duplicate records by their Odoo ID. Only duplicates reach this step — the record to keep never does.
