This page introduces some more advanced Excel topics that will help you push your Excel skills even further. All the lessons are about five minutes long (or less) so it won't take long to learn more, and do more.
This lesson shows you a way to capture the submission page when someone submits a Drupal 7 webform on your website. This is useful if you have a webform in a block on multiple pages, and you want to know which page someone was on when they submitted the page.
This lesson shows you how to calculate a running total between two dates in a column of data. An example might be calculating the total sales for the last 30 days up to today. Each row in the spreadsheet will calculate a new total based on the date in that row, counting back a specified number of days.
The COUNTIFS function in Excel counts the number of cells in a range that match a set of multiple criteria. COUNTIFS extends the COUNTIF function which only allows one criteria. It is similar to SUMIFS, which will find the sum of all cells that match a set of multiple criteria. This lesson shows you how to use COUNTIFS and provides some practical examples to help you understand how it works.
When writing a formula that references other cells, it can sometimes be useful to check that those cells contain a valid value. In this lesson, we'll look at Excel's ISNUMBER function as a way of doing this.
If you're using Excel to calculate dates, it is useful to know how to add (or subtract) a certain number of working or business days to a date. This lesson introduces the WORKDAY() function and shows you how to use it.
When you create a new Pivot Table, Excel either uses the source data you selected or automatically selects the data for you. But data changes often, which means you also need to be able to update your pivot tables to reflect the new or changed data. This lesson shows you how to update existing data, and add new data to an Excel pivot table.
In this lesson, we look at a specific example where you have a table of sales data, and you need to find out the name of the person who had the highest sales for the month. It's one of those things that seems like it should be easy until you actually try to do it. The solutions we present here are not the only way of achieving this, but the do have the advantage of solving the problem with a single formula. The methods here could also be used for a variety of other applications as well.
