How to load a package by M

Hi peeyee,
Thanks for reaching out to the Microsoft fabric community forum.

As the query is for a way to load any external package in M-Query, there is no direct way to load any external packages or libraries written in other programming languages like Python, R, C#.

If you still need any functionality from another language, Power BI allows you to include Python or R scripts as part of your queries using which you can execute Python or R code to process data and then bring the results into Power Query.

For more details on this you can refer to the following links -

You can also use APIs, if the external functionality is exposed through REST API. We use "Web.Contents" function to implement API integration in M-Query. This fucntion sends HTTP requests and retrieves responses in JSON, XML, or other formats.

Thank you.
