3-day Virtual Seminar

Data Transformation & Cleansing Using Power Query (ETL Concepts)

Overview

This webinar will train participants on Power Query-based Data Transformation & Cleansing, using ETL concepts commonly used in:

• MIS Reporting
  
• Data Analytics
  
• Power BI reporting pipelines

Participants will learn how to:

• import data from multiple sources
  
• clean and standardize datasets
  
• transform data for reporting readiness
  
• merge/append files automatically
  
• build a refreshable ETL workflow

The key outcome is:

• Stop manual cleaning
  
• Build repeatable transformations
  
• Refresh and generate clean data instantly

Why you should Attend

• Are you cleaning the same Excel data every day or every month manually?
  
• Does raw data come in different formats from different teams/vendors?
  
• Do your reports get delayed due to data cleaning?
  
• Do you make mistakes while copy-pasting and formatting reports?
  
• Do you want to automate your cleaning process with one Refresh button?
  
• Do you want to learn ETL concepts used in Data Analytics & BI tools?

Areas Covered in the Session

Understanding the ETL process

• Extract - Transform - Load (Power Query mindset)

Power Query Overview:

• Where Power Query is used (Excel + Power BI)
  
• Query Editor interface
  
• Applied Steps (how automation happens)

Importing data from different sources:

• Excel, CSV, Text
  
• Folder (combine multiple files)
  
• Tables, ranges

Data cleansing operations:

• remove blanks / nulls
  
• remove duplicates
  
• trim / clean text
  
• fix inconsistent naming
  
• replace values
  
• split columns / merge columns
  
• change data types correctly

Data transformation techniques:

• add conditional columns
  
• custom columns
  
• extract characters / numbers
  
• date transformation
  
• pivot/unpivot

Data shaping for reporting:

• normalize raw datasets
  
• set proper headers
  
• promote/demote headers

Merge & Append queries

• Merge (like VLOOKUP/XLOOKUP but professional)
  
• Append (combine multiple sheets/files)

Creating refresh-ready pipelines:

• refresh all
  
• auto update when new file comes

Query loading options:

• load to worksheet
  
• load to data model (Power Pivot / Power BI)
