When I first opened Power BI, I thought the exciting part would be building beautiful dashboards. I was wrong. It is such a powerful tool.
The real work and arguably the most important work starts long before creating charts. It starts with messy data.
As someone transitioning deeper into data analytics, I've realized that data cleaning isn't the boring step people make it out to be. It's where you develop the mindset of an analyst. Every duplicate, missing value, incorrect data type, or inconsistent entry tells a story about the quality of your data.
And if the data is wrong, your dashboard will simply visualize bad decisions.
