Protecting Small Business Spreadsheets: Locking Formula Cells & Permissions

1. Operational Challenge & Business Context

The Problem This Solves:When team members or clients accidentally type over complex formula cells, financial calculations break silently. Locking formula cells ensures spreadsheet templates remain durable.

A well-designed business template clearly distinguishes between Input Cells (where users enter data) and Calculation Cells (which should never be edited). Protecting sheets enforces this boundary.
