Open Mercato Migration Field Mapping Worksheet

The worksheet lets a team classify confirmed native targets, proposed custom fields, ignored data, and unresolved gaps. It verifies nothing by itself: the target entity and field must be confirmed in code or documentation. Comma-separated value (CSV) import and export run locally in the browser.

Do not paste production, personal, or secret data.

Field mapping worksheet

The worksheet does not check target entities or fields automatically. The team confirms them in code or documentation and records the result in the status column. Never paste production or personal data. Files are processed locally. Export neutralizes cells that begin with formula characters.
