What is Power Query in Excel?

Power Query is a powerful data connection and transformation tool built into Excel. It allows users to extract, transform, and load (ETL) data from a variety of sources using a user-friendly interface. With Power Query Editor, users can apply step-by-step transformations such as filtering, merging, and reshaping data, all without writing complex code. The processed data can then be loaded into Excel sheets or the data model for analysis.

Power Query simplifies repetitive data tasks by letting you create reusable queries that refresh with a click. It supports handling large datasets and automates cleaning processes efficiently. Compared to Excel formulas or VBA, Power Query has a gentler learning curve, making it ideal for both beginners and experienced Excel users.

Steps to Download the Power Query Add-on Excel

Follow the steps below to learn how to download Power Query Excel:

Step 1: On Microsoft’s official website, when you click on the download button, it redirects you to a dialogue box where you can opt for the correct download option.

Step 2: Choose the preferred file size and click on the “Next” option.

Step 3: Click on the “RUN” option to execute the download.

Step 4: To successfully complete your Power Query Microsoft download, Click on the “Finish” button.

Four Phases of Power Query

Power Query follows a structured ETL (Extract, Transform, Load) process through four main phases. These steps help users gather, clean, combine, and use data efficiently within Excel.

Connect

In the Connect phase, Power Query allows users to link Excel to various data sources such as databases, Excel files, web pages, or CSVs. Users can also enter login credentials or apply authentication settings to securely access the data.

Transform

Once the data is connected, the Transform phase lets users clean and shape it using built-in tools. You can remove errors, split or merge columns, filter rows, remove duplicates, and more, all through a visual interface without writing code.

Combine

This phase enables you to merge or append data from different sources to create a unified dataset. You can join tables using matching columns or stack datasets from similar sources, which is ideal for consolidating large or complex data.

Load

In the final phase, the cleaned and combined data is loaded into a chosen destination. You can insert it into an Excel worksheet, load it to the data model, or establish a connection that updates automatically when the source data changes.

Functions of Power Query

Power Query is a widely used ETL tool. It is an innovative tool which can save hours, reduce manual errors, and allow users to source data from a singular source of truth. Power Query can retain the user's data, transformation steps, and efficiently automating manual processes. Let’s take a closer look at some of its functions:

1) Transferring Data

Transferring data becomes manageable using the "Get and Transform Data" section of the Data tab in Excel.

You can transfer data from various sources:

1) Excel files (Workbooks), text or CSV files, XML files, and JSON files can all be read from.

2) SQL Server, Microsoft Access, and SQL Server Analysis Services are databases.

3) Excel Tables/Ranges, the Web, Microsoft Query, and OData feeds are among additional sources.

2) Modifying Data

The objective of Power Query is to modify data. This refers to editing the layout, reducing errors, and making the data more presentable to use.

Common data modifications in Power Query include:

a) Unpivot and pivot

b) Dividing/combining columns

c) Data Filtering

d) Adding customised columns

e) Removing blank, error, and header rows

f) Various data types

g) Insert values

Here's what the Power Query Editor Interface looks like:

Let’s take an example to understand a simple transformation process:

Go through the steps below to understand how to sort a table based on a single column:

Step 1: Enter the data in the editor

Step 2: Choose the preferred column to sort

Step 3: Tap on the filter icon

There are icons to sort your column in either ascending or descending order in the Sort group under the “Home” tab.

There is a drop-down menu indicator next to the column's name. The column sorting option appears when you pick the icon.

The buttons in the Sort group on the “Home” tab will be used to carry out the excel function. This operation adds a new step called Sorted rows to the Applied steps section.

3) Exporting to Excel

After finishing them all, you must export the editor's operations to our Excel sheet. Choose "Close and Load” from the Power Query Editor's Ribbon menu to perform this task.

After choosing this option, the Editor will be directed toward closing and this will help you get the result of your worksheet.
