Power Query & LET Functions Data Navigator

https://phronesis-solutions.com/ This reference build starts with a familiar problem: public data is available, but not yet ready to use. The workbook takes Eurostat’s monthly unemployment dataset and turns it into a controlled analytical interface. Power Query cleans and reshapes the raw sheets. LET formulas then build the navigation layer: period selection, country selection, population selection, dynamic charting and country-level summary statistics. Raw official data is converted into structured working data, then placed behind a simple interface that lets the user compare, filter and review without touching the underlying logic. The unemployment dataset is only the demonstration layer. The same approach can be adapted to inflation, GDP, wages, population indicators, interest rates, internal reporting files or any recurring dataset that needs to be cleaned once and reused many times.
