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 automatically verify target entities or fields: the team must confirm them in code or documentation and record the result in the status column. Never paste production data or personal data. Files are processed locally, and formula-prefixed cells are neutralized on export.

Reviewed 14 July 2026. Product facts were checked against both the public code at the cited repository revision and official documentation. Where documentation and code differ, this guide describes behavior supported by code. Interpretations and recommendations concern implementation work, not product guarantees.
