Convert a text value into a date in Excel
Sometimes you’ll find yourself working with dates in an Excel spreadsheet that have been pasted or imported into Excel from another datasource. When that happens, Excel can treat those dates as text – in other words, they look like dates but don’t behave like dates. For example you can’t sort by date properly. This lesson looks at several ways you can convert a date which Excel is treating as text into a proper date value in Excel.
Multiply two columns and add up the results using SUMPRODUCT
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.

Use SUMIFS to sum cells that match multiple criteria in Excel
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.
Using SUMIF to add up cells in Excel that meet certain criteria
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.
