Three months ago, Microsoft introduced the User-Defined Functions (UDFs) in the DAX language. From the first day, https://daxlib.org has been available to share libraries of functions with the Power BI community. We published DAX Lib with a low profile because we did not have many libraries available at the beginning, but now it is time to spread the word!
Using DAX Lib is fast and simple: copy the function code from a TMDL script in DAX Lib, then paste it into the TMDL view of your Power BI model and apply it. Watch the video to see a complete walkthrough.
Check out that video, as well as the functions available in the “DAX app store.”
