When you need to perform a lookup, your instinct tells you to use VLOOKUP. But, when your lookup uses multiple conditions and columns, you may be inclined to use SUMIFS. However, when the value you need to return is a text string, rather than a numeric value, you are precluded from using SUMIFS since it only…
In this post, we’ll perform a two-dimensional lookup with Excel’s VLOOKUP function. Objective Let’s begin by clarifying our objective and what is meant by the term two-dimensional lookup. We have stored our price list in a table, and the price for each item varies based on the region. This is illustrated in the screenshot below. To…
Let me ask you a question. How do you know when a user has entered a value into a formula cell, essentially overriding your formula? Since this is Excel, there are several ways to address this issue, but starting with Excel 2013, we can use conditional formatting with the new ISFORMULA function. Objective Our worksheet…
The terms Moving, Rolling, and Trailing are commonly used to describe the same calculation idea…that we want to operate on the previous say 3, 6, or 12 data rows. In this post, we’ll allow the user to define the number of rows to include and use the OFFSET function to dynamically define the desired range. Objective…
If you have a data table that is updated frequently, for example, a new column is added each month, you may want to find the sum of the last three columns. But, you don’t want to rewrite your formula each time you add a new column. Fortunately, you can accomplish this task with two lookup functions,…
Beginning with Excel 2013 for Windows, we can use Slicers to filter table data. In this post, we’ll explore how to use Slicers as a relatively easy alternative to conditional drop-downs. Objective When we want to allow a user to select a choice from a list of items, we often consider using the Data Validation feature to…
In this post, we’ll examine a couple of ideas for computing income tax in Excel using tax tables. Specifically, we’ll use VLOOKUP with a helper column, we’ll remove the helper column with SUMPRODUCT, and then we’ll use data validation and the INDIRECT function to make it easy to pick the desired tax table, such as single or married…
Previously, we explored using the INDIRECT function to refer to various tables in a workbook. In this follow-up post, we’ll expand the discussion and refer to individual table columns. Objective Let’s start with our objective. We have several tables in a workbook. They have the same structure and store department data. For example, here is…
In this post, we’ll allow the user to select a table name from a data validation drop-down and our Excel formulas will operate on the values from the selected table. Thanks to Neelima for asking about this technique! Objective Before we get too far, let’s be clear about our objective. We have several data tables in…
I recently picked up a copy of Stephen Few’s outstanding book Information Dashboard Design. First of all…wow! If your reports include any type of chart or graph, you owe it to yourself to pick up a copy of this incredible resource. Stephen developed a graph called a Bullet Graph, and in this post, I’ll walk through…
