Excel Power Query and Data Cleaning for Analysts

Analysts across African organisations still spend hours manually reshaping messy spreadsheets before any analysis can begin. This course teaches repeatable data cleaning and transformation using Power Query and advanced Excel features. Participants learn to turn inconsistent source files into reliable, refreshable datasets ready for reporting.

What you will be able to do

  • Connect Power Query to files, folders and databases as data sources.
  • Clean and reshape messy data through repeatable transformation steps.
  • Combine data from multiple sources using merges and appends.
  • Build refreshable queries that update when source data changes.
  • Apply data modelling techniques to support flexible analysis.
  • Document transformations so others can maintain and trust the work.
