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 is the last time you used the REPT function in Excel? REPT is one of Excel's little-known, overlooked and underutilized functions, yet it is very useful.
Here are 7 ways you can start using the REPT function:
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.
When using the VLOOKUP formula in Excel, sometimes you may end up with the ugly #N/A error. This happens when your formula can not find the lookup value.
In this tutorial, I will show you different ways to use IFERROR with VLOOKUP to handle these #N/A errors cropping up in your worksheet.
Using the combination of IFERROR with VLOOKUP allows you to show something meaningful in place of the #N/A error (or any other error for that matter).
The IF function is one of the most used functions in Excel. In my opinion, it is the foundation of all programming and Excel's formulae mastery.
However, it is also one of the most misused functions, especially nested IF. Especially now with Excel 2007 and beyond, you can nest up to 64 IF functions to form complex, slow and hard-to-understand IF THEN ELSE statement.
You don't need to slow or complicate your worksheet anymore, this article describes 6 alternatives to using nested IF functions.
A recent update to Excel allows you to set the default PivotTable layout.
Now, when you're building complex reports or performing one-off analyses, you can quickly get started with your favorite PivotTable layout. This feature is available for Excel 2016 on Windows as part of an Office 365 subscription.
The performance of OLAP PivotTables has also been improved.
