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 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.
The SUMIFS function in Excel allows you to sum the values in a range of cells that meet multiple conditions, or criteria. For example, you might use the SUMIFS function in a sales spreadsheet to to add up the value of sales of a specific product by a given sales person (e.g. the value of all sales of a microwave oven made by John). This lesson explains how to use SUMIFS.
Excel's VLOOKUP function is excellent when you want to find a value in a table based on a lookup value. But if your table includes your lookup value multiple times, you'll find that VLOOKUP can't do it. This lesson shows you how to use the INDEX function (plus some other functions) to find all matching values in a list, and return a value from another column in the same row. It also looks at how to do this when you want to return all values which are a partial match (i.e. a wildcard search) to the values in your lookup table.
The SUMPRODUCT function allows you to multiply two arrays of numbers together (e.g. Quantity Sold and Price Per Unit) and add the results each individual calculation together. Without the SUMPRODUCT function, you'll find yourself having to create a third column in which you multiply the Quantity by Price for each row, and then find the sum of all the individual formulas. This lesson shows you how to use SUMPRODUCT to do all that with just one formula.
This lesson shows you how to use Conditional Formatting in Excel to format cells containing dates that are in the past, using a conditional formatting rule that compares the date in a cell with today's date, and formats it a different colour if it is in the past. We'll also extend this conditional formatting example to check the value of another cell as part of our criteria for applying the formatting.
This lesson explains how to use Autosum. Autosum is a powerful feature that can save you time if you need to add up cells or columns of data. It is often faster than creating a formula by hand, especially when you have a large amount of data to add up. In this lesson you'll learn how to use Autosum, and some of its limitations.
