Grantvera helps you collaborate safely on Google Sheets without exposing your entire spreadsheet. Share only the ranges you choose, control exactly which cells are editable, and enforce validated inputs while formulas and sensitive data stay protected. Create secure links so collaborators can update their assigned range without needing access to the full sheet or even a Google account.
Grantvera adds a secure collaboration layer on top of Google Sheets so teams can collect updates from clients, teammates, or external collaborators without risking their spreadsheets.
Collaborators interact only with the part of the sheet you assign to them, reducing errors and preventing broken formulas.
