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.

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.

Printing from Excel can be very frustrating, especially if your spreadsheet is too wide or too tall to fit on a single page.
You can use the Scaling option in Page Setup to set limits on how many pages wide and tall your document should be when you print it. The problem with that is that you can find your page fits onto one page, but becomes too small to read. Not only that, but Excel ignores any manual page breaks you've entered. This lesson explains how you can print your spreadsheet so it automatically scales to be one page wide without forcing the rows into a single page.

Rounding in Excel refers to reducing the number of digits in a number to make it easier to work with. A common example is rounding a price to two decimal places. Rounding errors can cause havoc with your spreadsheets without you even realising it. A common mistake occurs when you change the display format of a number to show fewer digits after the decimal point and assume that the number has been rounded for use in other calculations. This lesson explains how rounding in Excel works, and shows you how to use the different rounding functions available in Excel.

If you work with large Excel spreadsheets, you'll probably know the hassle of scrolling left and right, up and down as you try to work with all that data. You can use the Zoom feature to make the spreadsheet smaller and fit more onto the screen, but that doesn't always give you the result you want. Often, it will make your spreadsheet too small or not small enough.
