Proofing empowers any stakeholder to easily review and approve your team’s content. Upload your file to a proof and send a review request to colleagues, vendors, clients, and more, even if they’re not shared to your sheet. Reviewers can pin comments, discuss their feedback with each other, and log their approval decisions. Upload a new version to the proof at any time to continue the process. Previous versions of the proof will remain available in view-only mode.
