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:

• Reviewing the entire workbook, not just the current tab.
• Understanding Filters.
• Identifying hidden rows, columns, and worksheets.
• Identifying & deciphering formulas.
• Understand the Freeze Panes display feature.
• Finding and expanding truncated text.
• Identify the boundaries of a worksheet.
• Finding each worksheet's print formatting.

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:

• Relative cell references.
• Absolute cell references.
• Mixed cell references.

Understanding these different type of cell references will help you work with formulas and save time (especially when copy pasting formulas).

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.
