Transform Irregular Tables into Structured Data in Power Query

In this Power Query tutorial, we convert a semi-structured dataset into a clean analytical table. The source structure mixes dates, products, and sales values across multiple rows, making it difficult to analyze directly. Using a dynamic Power Query solution, we reconstruct the correct structure: Date | Product | Sale In this video you will learn: • How to detect patterns in irregular datasets • Techniques for building dynamic Power Query transformations • Methods for extracting structured information from mixed data • Advanced data preparation strategies for Power BI and Excel This technique is extremely helpful for real-world data transformation scenarios.
