Mastering Excel takes some experience and patience, but it's easy to make mistakes even if you've been using it for a long time. Sometimes, choices seem like a brilliant idea—until they're not, and the resulting problems are hard to troubleshoot.
In this article, I share 10 ways to avoid actions that seem good... at the time:
The tutorial shows how to use
IFERROR in Excel to catch errors and replace them with a blank cell, another value or a custom message.
You will learn how to use the
IFERROR function with
INDEX MATCH, and how it compares to
IF ISERROR and
IF formulas are extremely useful for complex decision making on a spreadsheet, but they can also be long, messy and convoluted.
This blog post explores 4 alternatives which are easier, faster and cleaner than the classic nested
VLOOKUPfor an exact match.
VLOOKUPfor a range lookup.
When it comes to VBA, it's almost too easy to make a mistake. These mistakes can cost you greatly, both in time and in frustration.
In this post, I'd like to help you avoid these typical mistakes and make you a better VBA programmer:
Application.ScreenUpdating = False.
Learn why using an Excel Table as the source of a Pivot Table can save time and prevent errors.
The reasons why you should use Tables for the source data range of your Pivot Tables are:
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).
