Other useful tools

While DAX Guide is foundational, these other tools can help you format formulas, test queries, check performance and generate code.

To reinforce what you learn, keep this practical reference handy: 12 Essential Power BI DAX Formulas Every Report Creator Should Master. This article covers essential DAX formulas, with examples, use cases, and practical tips.
DAX Formatter (SQLBI): An online formatting tool that cleans up messy DAX code. Paste in your DAX formula and it auto-indents and spaces it for better readability. This helps learners read and debug formulas more easily.
DAX Studio: A free, open-source desktop app for writing and running DAX queries. It connects to Power BI or other tabular models and includes performance analysis features (timings, query plan). Great for testing DAX queries and diagnosing slow formulas.
AI-Powered DAX Code Generator (Data Mentor): An AI-driven tool where you describe what calculation you need (in plain language) and it generates the corresponding DAX formula. This can accelerate learning by providing instant example code for new DAX tasks. This tool from may require signup.
Tabular Editor: A modeling utility (for Power BI/SSAS) that includes a built-in DAX debugger. It lets you step through DAX code like in an IDE, examining intermediate results to find logic errors. It’s invaluable for advanced DAX development and error checking.
DAX.do: An online DAX playground by SQLBI. You can write DAX queries in the browser, run them to see results, and even save/share code snippets. It’s a handy sandbox for trying out DAX expressions and learning interactively.
