#Data Cleaning

Data cleaning is boring but it's literally the difference between getting promoted and staying stuck 🧹⁠ ⁠ Most analysts delete messy rows and lose valuable data. Here's the system that actually works:⁠ ⁠ Expose quality issues first (nulls, inconsistent formatting, logical errors). Handle nulls with coalesce (fill gaps with defaults, don't destroy sample size). Remove duplicates with window functions (row_number to keep originals, discard copies). Standardize data with case statements (USA, US, U.S.A. all become one value). Combine into a production grade view (automated system, not manual Excel edits).⁠ ⁠ The difference between junior and senior? Juniors clean manually every time. Seniors build systems that clean automatically.⁠ ⁠ Comment "CODE" for the full SQL script and save this before your next messy dataset 📊⁠ ⁠ #DataCleaning #SQLForDataAnalysis #DataQuality #SQLProjects
