# Excel 2016 from Scratch Exercise Custom Number Formats B

## An Excel tutorial by Peter Kalmstrom In this exercise in the Excel 2016 from Scratch series, Peter Kalmstrom shows how to set custom number formats in Excel.

Text cannot be calculated, so a custom number format is useful when you want to add some text, for example a sort, in a cell. If you use a customer number format for that, Excel will stil consider the figures in the cell a number, and it will be possible to use it in a calculation.

As an example Peter uses ferries that take passengers around in the Stockholm archipelago. For the calculation of number of tours and passengers, it is more clear to have the sorts "pass" (for passanger) and "tour" in the cells where the number is given.
