Shaping Data with M

M data shaping pivots and unpivots for reporting formats.

Introduction to M Data Shaping

Data shaping in M involves transforming data into a format suitable for analysis and reporting. Two primary operations used for this purpose are pivoting and unpivoting. These operations help in restructuring data to meet specific reporting needs.

Understanding Pivoting

Pivoting is the process of turning unique values from one column into multiple columns in a dataset. This transformation is useful when you want to summarize data for better readability or analysis.

Exploring Unpivoting

Unpivoting is the reverse of pivoting, where you transform columns into rows. This is particularly useful when you need to normalize a dataset or prepare data for certain types of analysis or visualizations.

Practical Applications

The ability to pivot and unpivot data allows analysts to prepare datasets for various types of reports and dashboards. For instance, pivoting can help summarize sales data by category, while unpivoting can transform wide datasets into a long format, making them easier to plot in time series visualizations.

Conclusion

Mastering data shaping techniques like pivoting and unpivoting in M is crucial for efficient data analysis and reporting. These transformations enable you to tailor data to your specific needs, enhancing both the flexibility and the insightfulness of your reports.
