Excel Custom Number Formats

Number formats control how numbers are displayed in Excel. The key benefit of number formats is that they change how a number looks without changing any data. They are a great way to save time in Excel because they perform a huge amount of formatting automatically. As a bonus, they make worksheets look more consistent and professional.

What can you do with custom number formats?

Custom number formats can control the display of numbers, dates, times, fractions, percentages, and other numeric values. Using custom formats, you can do things like format dates to show month names only, format large numbers in millions or thousands, and display negative numbers in red.
