Q. Is there a list of standard Excel design rules we should be following as we create new Excel worksheets?
A. By following a common set of spreadsheet design rules, companies can produce more consistent workbooks that may be easier to review, edit, and use by others in their organizations:
The Wells Fargo inadvertent disclosure episode provides a high-profile reminder that attorneys who are responsible for reviewing and producing client documents must thoroughly understand those documents.
As reported by the New York Times, the inadvertently produced material "included copious spreadsheets with customers' names and Social Security numbers, paired with financial details like the size of their investment portfolios and the fees the bank charged them."
Here is a list of skills that I think every reviewer must have to competently review spreadsheets in the eDiscovery context:
A worksheet in Excel is made up of cells. These cells can be referenced by specifying the row value and the column value.
The power of Excel lies in the fact that you can use these cell reference in other cells when creating formulas.
There are three kinds of cell references in Excel:
Understanding these different type of cell references will help you work with formulas and save time (especially when copy pasting formulas).
Microsoft quietly replaced the comfortable Text Import Wizard from Excel and replaced it with the "Get & Transform" tools.
The "Get & Transform" tools offer a lot of options and are very powerful. Unfortunately, they are quite complicated to use. Here is what you should now.

This tutorial explains what an Excel name is and shows how to define a name for a cell, range, constant or formula. You will also learn how to edit, filter and delete defined names in Excel.
Looking around, a few things are apparent:
This article (see page 7) looks at how we can address the issues and make spreadsheets more user-friendly and faster to use, less prone to error and more capable of completing the tasks required of them.
Sometimes a secondary axis is a necessary evil. After all, most of the time you can't plot big numbers and little numbers in the same chart without the little numbers getting lost in the scale.
With a few simple changes, we're able to present our readers with a chart that's quick and easy to read. Let's be honest, anything less would be a waste of their time and yours.

When looking at other people's VBA code in books or on the internet we often see the
Dim statement being used to declare variables.
It is possible to write valid VBA code without declaring variables, so why bother?
This blog discusses the advantages and disadvantages of declaring variables in VBA.
