Protected Ranges
What This Does
Protected ranges restrict who can edit specific cells—lock formula rows while letting teammates edit input areas.
Why It's Useful
One bad paste destroys a model. Protection separates template from data entry.
How to Do It
- Select cells → Data → Protect sheets and ranges
- Set permissions: only you, or named editors
- Add a description so others know why it is locked
- Warning-only mode alerts without blocking
Try This Now
Protect a formula row and confirm edits are blocked.
Mental Hook: Lock the math, free the input.
