Something most people don't realize about data analysis 📊 80% of a data analyst's time isn't spent analyzing — it's spent cleaning. Messy column names. Duplicate rows. Dates stored as text. Missing values scattered randomly. Before a single insight comes out, all of that has to be fixed first. Working on my Revenue Dashboard project taught me this the hard way — half the "analysis" was actually detective work: figuring out why a SUMIFS formula was returning zero, only to realize a date field was formatted as text, not a date. The real skill in data analysis isn't just formulas or dashboards. It's patience — knowing that clean data is the actual hard part, and everything after that is just the reward. #dataanalytics #ExcelTips #DataCleaning #LearningInPublic
