Alternative place to develop PowerQUERY/M code

Hi robm135 

To run M code, it requires Mashup Engine. Mashup Engine is not a stand-alone application. It is embeded in some desktop tools like Excel, Power BI Desktop, Visual Studio... Reza Rad has a blog about it: What Is Power Query? Introduction to Data Mash-up Engine of Power BI - RADACAD

If you don't want to install Visual Studio, you can try Power Query Online in Power BI Dataflow/Power Platform Dataflow. The experience is similar to that in Power BI Desktop and there is no code intellisense there. 

Here is one tool for your reference, but it still requires Visual Studio. 

GitHub - gsimardnet/PowerQueryNet: Run M Language (Power Query Formula Language) from anywhere.
