The Complete Guide to Cleaning, Transforming, and Preparing Real-World Datasets for Analysis
Are you tired of spending hours cleaning messy spreadsheets or trying to make sense of inconsistent data? Do you want to master the essential data wrangling skills that professionals use every day to turn chaotic raw data into clean, structured datasets ready for analysis?
You’ve found the right course.
Whether you’re a beginner, a data enthusiast, or a working professional looking to improve your data handling skills, this course will teach you how to clean and transform real-world data using Microsoft Excel, Power Query, and Python (pandas) — all with hands-on projects and real business scenarios.
