Here, 2
specifies the column to sort (revenue), and -1
sorts in descending order.
What It Does: Filters a range based on criteria.
Why It’s Powerful: Simplifies complex filtering tasks and avoids the need for helper columns.
Example:
Filter for sales above $10,000:
excel
Copy code
=FILTER(A2:B100, B2:B100>10000)
What It Does: Generates an array of sequential numbers or dates.
Why It’s Powerful: Useful for quickly creating structured lists or calendars.
Example:
Generate a sequence of 10 numbers:
excel
Copy code
=SEQUENCE(10)
What It Does: Merges text from multiple cells (CONCAT is the improved version of CONCATENATE).
Why It’s Powerful: CONCAT removes the need for specifying every cell, working efficiently with ranges.
Example:
Combine a product name and its category:
excel
Copy code
=CONCAT(A2, " - ", B2)

This blog provides actionable insights to help users tap into the full potential of Excel and Power BI, empowering businesses with smarter, data-driven strategies
Power BI has rapidly become one of the most popular business intelligence tools, empowering users to create dynamic dashboards, visualize data, and perform powerful analyses. One of the reasons for its popularity is DAX (Data Analysis Expressions), a collection of functions, operators, and constants that can be used to manipulate data. This blog dives deep into DAX, exploring the creation of custom functions to enhance your Power BI projects.
DAX is a formula language for data modeling, enabling users to perform complex calculations and data analysis. It extends Power BI’s capabilities by allowing users to create new information from data in existing columns.
DAX formulas begin with an equals sign and are often used in calculated columns or measures.
DAX
Total Sales = SUM('Sales'[SalesAmount])
This code calculates the total sales amount by summing up all values in the SalesAmount
column of the Sales
table. It’s a straightforward example, but understanding it is fundamental for using DAX effectively.
Creating custom DAX functions can save time and add a layer of specificity that generic formulas lack. Let’s walk through a step-by-step example of building a custom DAX function to calculate year-over-year growth.
The first step is to calculate the total sales for each year.
DAX
Total Sales per Year = CALCULATE(SUM('Sales'[SalesAmount]), YEAR('Sales'[Date]) = YEAR(TODAY()))
This formula calculates the total sales amount for the current year by using the CALCULATE
function and filters only the data from the current year.
Now, let’s calculate the sales from the previous year.
DAX
Previous Year Sales = CALCULATE(SUM('Sales'[SalesAmount]), YEAR('Sales'[Date]) = YEAR(TODAY()) - 1)
This function is similar to the first but filters to get the sales for the previous year by subtracting one from the current year.
Finally, use the two previous formulas to calculate the growth rate.
DAX
YoY Growth = DIVIDE([Total Sales per Year] - [Previous Year Sales], [Previous Year Sales], 0)
This custom DAX function subtracts the previous year's sales from the current year's and then divides it by the previous year’s sales to get a growth percentage. The DIVIDE
function also ensures that if the previous year’s sales are zero, it returns 0 instead of an error.
Once you have created the custom DAX functions, you can use them in Power BI visualizations to analyze year-over-year growth dynamically. Dragging and dropping these custom measures onto a line or bar chart enables you to quickly see trends over time.
Using variables within DAX functions can make complex calculations easier to read and faster to execute.
DAX
YoY Growth with Variables = VAR CurrentYearSales = CALCULATE(SUM('Sales'[SalesAmount]), YEAR('Sales'[Date]) = YEAR(TODAY())) VAR LastYearSales = CALCULATE(SUM('Sales'[SalesAmount]), YEAR('Sales'[Date]) = YEAR(TODAY()) - 1) RETURN DIVIDE(CurrentYearSales - LastYearSales, LastYearSales, 0)
In this example, CurrentYearSales
and LastYearSales
are stored as variables, and then these variables are used in the final calculation. This method not only makes the code more readable but also optimizes performance in larger data models.
Here are some optimization tips for better performance when using DAX:
