Formula Auditing
5

The formula auditing toolbar allows the developer to
determine both precedents and dependents of a cell.

Precedents are the cells that provide data to a formula
in the current cell .

Dependents are the formula cells that use (reference)
the current cell.

You may also Evaluate a formula

Data Validation
6

The Data Validation command allows the
developer to restrict the values that may be
entered in a cell.

For example, you can specify that a numeric
value be between 0.0 and 1.0 (i.e. between
0% and 100%)

Reviewers
7

Have others review your spreadsheet.

Make use of Excel’s ability to create a
shared workbook – one that is accessible to
multiple users.

Shared workbooks may be modified via tools
on the Reviewing toolbar or via the Track
Changes command.

Protection
8

Protected worksheets allow users to modify only a
limited number of cells

You must first specifically unlock those cells you
want to allow the user to change

Then you must protect the worksheet. The unlock is
‘stronger’ than the protect – odd

You can later unprotect the worksheet if you’d like,
and lock/unlock the cells
