The
video below demonstrates how to use Excel cell styles. Peter
Kalmstrom, CEO and Systems Designer, explains how to lock
certain cells in a spreadsheet and let other cells be open
for editing.
As an example Peter uses a spreadsheet with sales estimates
for each month of the year, but the idea can be used for
any data.
Peter uses Excel 2013 for his demo, but most of what he
does is possible to do in earlier versions also.
