What is the best method to give a collaborator Viewer access to only specific data from a sheet?

The best method to give a collaborator Viewer access to only specific data from a sheet is to publish a report and provide them with the link. This approach allows you to customize and control exactly what information is included in the report, ensuring that the collaborator sees only the relevant data needed for their tasks.

By publishing a report, you can filter and organize the information effectively, presenting only the necessary details without exposing the entire sheet. This way, you maintain confidentiality and streamline the viewing experience for the collaborator, which is especially useful in collaborative environments where data sensitivity might be a concern.

While sharing a specific view may seem like a viable option, it may not have the same level of customization and security as a report. Publishing the entire sheet would expose all data, which defeats the purpose of limited access, and sharing the sheet with restricted access might still allow the collaborator to see more than just the specific data they need. Therefore, publishing a report strikes the perfect balance between accessibility and control over the information shared.
