Your First Power Query Project: A Step-by-Step Example
Let’s say you run a small business in Belgaum and have sales data scattered across multiple Excel files from different months. Here’s how Power Query can help:
Step 1: Open Excel and Find Power Query Open Excel and click on the “Data” tab. Look for “Get Data” – this is your gateway to Power Query.
Step 2: Connect to Your Data Click “Get Data” and choose your source. For Excel files, select “From File” then “From Workbook.” Browse and select your first sales file.
Step 3: Preview and Transform Power Query opens a preview window showing your data. This is where the magic happens. You can:

Step 4: Combine Multiple Files Here’s where Power Query shines. If you have multiple monthly sales files with the same structure, Power Query can combine them all automatically. Choose “From Folder” instead of individual files, and it will merge everything for you.
Step 5: Load Your Clean Data Once you’re happy with the transformations, click “Close & Load.” Your clean, combined data appears in a new Excel worksheet, ready for analysis.

Document Your Steps Power Query automatically records each step you take. Review these steps to understand what happened and learn for next time.
Use Descriptive Names When creating queries, give them clear names like “Monthly_Sales_Clean” instead of generic names like “Query1.”
