DAX Studio and DAX Guide

Filed under: Data Warehousing — Vincent Rainardi @ 7:36 pm

Thanks to Darren Gosbel and others, the Power BI, Power Pivot and SSAS Tabular communities now have a tool to test DAX. It is DAX Studio (, which is a superb tool. Not only it enables us to test ideas flexibly, but it also enables us to troubleshoot and optimise DAX queries.

With DAX Studio we can:

  • Connect to Power BI, a Tabular server and to Power Pivot and run DAX queries on them all.
  • Browse the model to understand the tables and columns
  • Run DMVs to get the measures, hierarchies, dimensions
  • Understand the query plans, Storage Engine and Formula Engine and timing.
  • Format our DAX queries
  • Capture DAX queries that we run in Power BI (and therefore allowing us to improve their performance)

It is an indispensable tool for anyone working in DAX. With Power BI being ever so popular, the demand for DAX is highly increasing. It was Darren Gosbel who primarily created DAX Studio, with Marco Russo wrote a small part of it.

Marco and Alberto wrote DAX Guide ( It is so comprehensive, so detail, so complete. It contains every DAX function in Power BI, in Excel, in Tabular, Azure AS and in SSDT. For every function it describe the syntax, the return values, the parameter, the example, and it describes them in detail. Just look at how it explain the Calculate function. The context transition is there, the filter is there, the order of evaluation is there, the modifier is there. It’s so complete.

Thank you Darren, Marco & Alberto, for creating these two very useful tools for all of us.

PS. All other tools related to DAX, Tabular and indeed other BI tasks are listed here:, e.g. VertiPaq Analyzer, Tabular Editor, BISM Normalizer, DAX Editor, Power Pivot Utilities, DAX Date Template, SSAS Tabular Translator, etc. Note: these tools are written by many people.

Correction, 5/11: DAX Studio was written mostly by Darren Gosbel:, not Marco or Alberto. My apologies for this mistake. Thanks Marco for your correction.


  1. Hi Vincent,
    the main DAX Studio developer is Darren Gosbell, who is a Microsoft MVP living in Melbourne, Victoria (Australia). His blog is

    I wrote a small part of the tool, which is open source and open to other contribution. Of course, we created a page to help people looking for these tools, but we did not wrote all of them! 🙂
    Thanks for correcting the article if possible!
