This lesson shows you how to write formulas using INDEX and MATCH to let you perform lookups that VLOOKUP can't, and which run much faster on large lookup tables than VLOOKUP. This lesson explains how INDEX and MATCH work on their own, and then shows you how to write an INDEX MATCH formula that can look left as well as right, and performs much faster than VLOOKUP on large tables.
If you want to learn Excel, this lesson covers ten important things that we think you need to know if you are going to use Excel effectively. Even if you've been using Excel for a while, check this lesson out to make sure you have the basics covered.
VLOOKUP allows you to look for a specified value in a column of data inside a table, and then fetch a value from another column in the same row. An example might be where you need to find the sales for a specific salesperson from within a monthly sales report. In this lesson you'll learn how to use VLOOKUP in your spreadsheets by walking you through several simple examples. The lesson will also highlight some shortcomings of VLOOKUP, plus a solution to those shortcomings.
The IF() function in Excel allows you to evaluate a situation which has two possible outcomes (e.g. sales are greater than $1000) and calculate a different value for each outcome. However, sometimes you need to work with situations where there are more than two possible outcomes. That's where multiple, or nested, IF functions come in handy. In this tutorial we'll cover how to use nested IF functions to calculate sales commission for a team of sales people, given a range of different commission rates.
The SUM function in Excel allows you to add up the values in a range of cells. However, sometimes you only want to add up the cells that meet certain criteria. That's where the SUMIF function comes in handy, along with the more capable SUMIFS function.
Excel offers a couple of handy functions that you can use to calculate the smallest and largest values in a range of cells. They are simple functions that go by the names of MIN() and MAX(). This lesson shows you how to use them. It also introduces SMALL() and LARGE(), functions which duplicate what MIN and MAX do, plus more besides.
Sometimes you need to count the number of cells in a spreadsheet that contain a value or set of values. The COUNTIF function allows you to do this by counting only those cells in the range that meet the criteria you set. This lesson explains how to use COUNTIF, and provides an example of how you can use it.
Excel offers a number of ways to find rows that contain duplicate values. However, most of them focus on finding rows where the value in just one column is repeated. In this lesson, we look at how to use the COUNTIFS function to find rows where values in moree than one column is repeated. We then use the COUNTIFS function in combination with Excel's Conditional Formatting feature to highlight duplicate and even triplicate rows.
This lesson provides a way in Drupal 7 to hide or show an individual menu item based on the location of each visitor. The use case for this example was to show a Shop menu item to visitors in New Zealand and Australia, and hide it for visitors from all other countries.
