OVERVIEW

About Power Query and Data Transformation for Office Tasks

Power Query makes repetitive data preparation more reliable. Instead of manually fixing the same files each time, learners design repeatable transformations that standardize raw inputs.

LEARNING OUTCOMES

What You Will Learn

  • Clean and transform raw office data.
  • Merge and shape multiple data sources effectively.
  • Create repeatable reporting pipelines.
TOPIC GUIDE

Learn Power Query and Data Transformation for Office Tasks

Prepare messy inputs

Office data often arrives in raw or inconsistent formats. Power Query helps remove blanks, split combined columns, normalize text, and convert values before using them in a report.

Create repeatable transformations

Build transformation steps that can be reapplied whenever the same file is received. This reduces manual effort and prevents one-off fixes from being lost when the source changes.

Combine multiple sources

Merge sales, attendance, or operations data from different sheets or files into a single reporting table. Review joins carefully and keep a clear record of which columns are used.

Document the process

Every transformation step should have a purpose. A clean and reviewed process is easier to explain, debug, and maintain when responsibilities change.

PRACTICAL EXAMPLE

Example / Code

Example 
let
    Source = Excel.CurrentWorkbook(){[Name="SalesData"]}[Content],
    Cleaned = Table.TransformColumns(Source, {{"Date", each Date.From(_), type date}}),
    Filtered = Table.SelectRows(Cleaned, each [Amount] <> null)
in
    Filtered
TRY IT YOURSELF

Practice Task

Apply what you learned with a practical activity.

Use Power Query to combine two office datasets, standardize field names, and prepare a clean summary table ready for KPI reporting.
