KNIME for Beginners: No-Code Data Cleaning & ETL Case Study

Learn how to clean, transform, and prepare real-world data using KNIME without writing a single line of code.

In this hands-on course, you will work on a real consulting-style case study based on an energy drinks dataset. You will learn how to turn messy, unstructured data into clean, analysis-ready datasets that can be used for reporting and decision-making.

You will build KNIME workflows step by step and learn how to automate data preparation processes. By the end of the course, you will be able to prepare data for tools such as Power BI or Tableau and apply structured data transformation techniques in real-world scenarios.

What makes this course different

This course is built around a practical business scenario rather than isolated feature demonstrations. You will not just learn KNIME concepts, but apply them step by step to solve a realistic data problem, similar to how data analysts and consultants work in practice.
