Introduction To M In Power Query And Power BI

Since last week’s post proved very popular (it turns out people want video – who knew?) I thought I’d post the recording of a presentation I did earlier this year at the Power BI User Group in Wellington, New Zealand, called “Introduction to M in Power Query and Power BI”. It’s a session I’ve presented at various conferences and user groups over the years but this is the best version of it I think:

It’s an hour-long introduction to the M language that sits behind Power Query in Power BI, Excel, dataflows, Analysis Services and other tools. It covers pretty much everything you need to now about the language including let expressions; tables, records and lists; error handling; and writing custom M functions.

If you’re keen to watch even more Power BI-related videos, my colleague Matthew Roche has just started his own YouTube channel and published a video on dataflows vs datasets.
