How to Work with Data Cleaning and Deduplication in Odoo 18 (Enterprise)

Maintaining clean and accurate data is crucial for any business. In Odoo 18 Enterprise, the Data Cleaning feature helps you identify and remove duplicate records, ensuring your database is consistent and reliable. This is especially important for contacts, products and other master data that grow over time.

Here’s a step-by-step guide on how to use Data Cleaning and Deduplication effectively.

1. Accessing the Data Cleaning Feature
  * Log in to your Odoo 18 Enterprise account.
  * Navigate to the Data Cleaning module from the dashboard.
        (If it’s not visible, you can search for “Data Cleaning” using the search bar.)

2. Selecting the Model to Clean 

  * Goto Data Cleaning Module > Duplicates

3. Reviewing Duplicate Records
  * Odoo presents a list of potential duplicate records in a clean, easy-to-review format.

  * “John Doe” vs. “John A. Doe”
  * Emails with typos
  * Duplicate phone numbers

4. Merging Duplicate Records
  * Select the records you want to merge.
  * Click Merge.

  * Confirm the merge and Odoo will combine the records, preserving all relevant linked data such as invoices, leads, or tasks.
  * Data Cleaning Module > configuration > Field cleaning
