How to use power query in excel

Answer

Power Query is a tool in Excel used to extract, transform, and load data from various sources into Excel. It helps clean, reshape, and organize large datasets efficiently.

What is Power Query?

Power Query is a data connection technology that enables users to import data from external sources, clean it, transform it, and load it into Excel for analysis. It is ideal for repetitive data tasks and complex data preparation.

How to Access Power Query in Excel

1. Open Excel.

2. Go to the Data tab on the Ribbon.

3. Locate the Get & Transform Data group.

4. Options include:

   • Get Data → Choose from File, Database, Online Services, or Other Sources.

   • From Table/Range → Create a query from an existing Excel table or range.

Windows vs. Mac:

• On Windows, all Power Query options are available under the Data tab.

• On Mac, only limited Power Query features are available, mainly From Table/Range and Get Data from CSV/Workbook.

How to Import Data Using Power Query

1. Click Data → Get Data → From File → From Workbook (or choose another source).

2. Select the file and click Import.

3. In the Navigator window, choose the table or sheet to load.

4. Click Transform Data to open the Power Query Editor.

How to Transform Data

Power Query Editor provides tools to reshape data without altering the original source.

1. Remove Columns or Rows

   • Select unwanted columns or rows → Right-click → Remove.

2. Filter Data

   • Click the filter icon on a column → Choose criteria → Apply filter.

3. Split or Merge Columns

   • Select a column → Home → Split Column → Choose by delimiter or number of characters.

   • Select multiple columns → Transform → Merge Columns → Choose separator.

4. Change Data Types

   • Select column → Transform → Data Type → Choose appropriate type (Text, Number, Date).

5. Group Data

   • Select a column → Transform → Group By → Aggregate data with sum, average, or count.

6. Add Custom Columns

2. Options include:

   • Close & Load → Load to new worksheet.

   • Close & Load To → Load to table, PivotTable, PivotChart, or only create a connection.

Benefits of Using Power Query

1. Automates repetitive tasks with one click.

2. Connects to multiple data sources: databases, CSV, web pages, or APIs.

3. Cleans messy data efficiently without manual editing.

4. Reduces human error in data preparation.

5. Supports large datasets beyond normal Excel limitations.

Example Scenario

Suppose you receive a monthly sales report in CSV format with extra columns and inconsistent date formats.

Steps to clean with Power Query:

1. Get Data → From CSV → Import file.

2. Remove Columns → Delete irrelevant columns like Notes or Comments.

3. Change Data Type → Convert Date column to proper Date format.

4. Filter Rows → Keep only sales greater than 0.

5. Load → Close & Load → Ready for analysis.

This process avoids manual editing, ensuring accurate and consistent reports.

Power Query transforms Excel from a simple spreadsheet tool into a powerful data management platform, saving time and improving accuracy in analysis.
