Data Mashup Cmdlets import and export Power Query from most Microsoft Power BI and Microsoft Excel files; however, they don’t include a GUI editor. Microsoft’s new Power Query / M Language extension for Visual Studio Code provides a graphical editing experience for mashups, with syntax highlighting, validation, and IntelliSense, but doesn’t read or write PBIX, PBIT or XLSX files.
What if the two could be married? Imagine…if this were possible, you could use VSCode to externally edit the Power Query code saved in your Power BI and Excel files….
You’re looking for all mashups that touch column “LegacyAmount”…or maybe the task is to find all files whose Power Query uses variable “CalculatedDiscount”…or perhaps you’re trying to locate any M code referencing server names that match the regular expression pattern “SomeServer(0|[2-6]\d)“. Ultimately, you need to search the Power Query mashups in an entire directory (or directory tree) of Microsoft Excel and Microsoft Power BI files. You could open files one at a time and check each by hand…ouch! Is there an easier way to quickly search Power Query across multiple files?
