Formatting Dates, Numbers, and Times with the FORMAT Function in Power BI

In today’s blog post, I will explain how to use the FORMAT function in Power BI. The FORMAT function is a powerful tool that allows you to format numbers, dates, and other values according to your specific requirements. This function is particularly useful when you want to present your data in a more readable and user-friendly format.

What is the FORMAT Function?

The FORMAT function in Power BI is used to convert a value to text according to a specified format. It is especially handy when you need to display data in a particular way, such as showing a date in a specific format or converting a number to a currency format.

The syntax of the FORMAT function is as follows:

• value: The value you want to format. This can be a number, date, or time.
• format_string: A string that defines the format you want to apply to the value.

Common Use Cases for the FORMAT Function

Formatting Dates:

The FORMAT function can be used to display dates in different formats. For example, if you have a date field that you want to display as "January 01, 2024," you can use the following expression:

mathematica

FORMAT([Order Date], "MMMM dd, yyyy")

This will format the date as "Month Day, Year," such as "January 01, 2024."

Formatting Numbers:

If you want to format numbers as currency or percentages, the FORMAT function is perfect for the job. For example, to format a number as currency, you can use:

FORMAT([Sales], "Currency")

This will display the sales amount with a currency symbol, such as "$1,000.00."

Custom Number Formatting:

You can create custom number formats using the FORMAT function. For instance, if you want to display a number with commas as thousands separators, you can write:

FORMAT([Sales], "#,##0")

This will display the number 1000000 as "1,000,000."

Formatting Time Values:

The FORMAT function can also be used to format time values. For example, to display a time value in the format "hh

AM/PM," you can use:

FORMAT([Time], "hh:mm tt")

This will display the time as "02:30 PM."

Advantages of Using the FORMAT Function

• Consistency: The FORMAT function ensures that your data is displayed consistently across your reports.
• Flexibility: You can easily switch between different formats without altering the underlying data.
• Readability: Properly formatted data is easier for users to understand and interpret.

Practical Example: Using FORMAT in a Report

Let’s say you have a sales report that includes order dates and sales amounts. You want to display the order dates in a "Month Day, Year" format and the sales amounts as currency. You can achieve this using the FORMAT function as follows:

mathematica

Formatted Date = FORMAT([Order Date], "MMMM dd, yyyy")

Formatted Sales = FORMAT([Sales], "Currency")

These calculated columns will make your report more user-friendly by presenting the dates and sales in a clear, readable format.
