The Data Discovery & Mapping app helps streamline the process of understanding and preparing client data for use in the Zeta Marketing Platform. Instead of manually reviewing every column in a sample file, users can upload a CSV or JSONL file and let the app generate a structured data profile.
The app analyzes the uploaded file to identify field types, detect formats, flag sensitive fields, recommend primary key candidates, and generate plain-English field definitions. It also provides recommended mappings from source fields to ZMP’s standard profile schema.
Navigation
If you do not see the Data Discovery & Mapping app, please reach out to your Zeta support or account team for access assistance.
The Data Discovery & Mapping app is accessible from the Applications menu in ZMP.
When you open the app, you land on the Data Profiles list. This is the central hub for saved profiles within the current account.
-
Each row represents a saved data profile and may include details such as profile name, creation date, last modified date, and creator.

-
When analysis is complete, the profile is ready to save.
Do not close the page while the analysis is running. If the analysis fails, remove the file and try again. If the issue continues, contact your Zeta support team.

Best Practices
-
Use a representative sample file with typical values and formats. Include all columns expected in the final data feed, even if some are sparsely populated.
-
Review the recommended primary key first, since an accurate identifier is important for customer profile creation and activation.
-
Review sensitive fields carefully and confirm that any required privacy or compliance processes are followed before production use.
-
Use the data profile and mapping exports to support review, sign-off, and implementation planning.
