Unlock the Power of Excel: Using SQL Queries via Power Query to Inquiry a Different Excel Spreadsheet

Are you tired of manually searching through multiple Excel spreadsheets to find the data you need? Do you wish there was a way to easily inquiry data from one spreadsheet to another without having to copy and paste? Look no further! In this article, we’ll show you how to use SQL queries via Power Query to inquiry a different Excel spreadsheet, making your data analysis tasks more efficient and accurate.

What is Power Query?

Power Query is a powerful data manipulation and analysis tool built into Microsoft Excel. It allows you to connect to various data sources, transform and combine data, and load it into your Excel worksheet. Power Query is an ETL (Extract, Transform, Load) tool that enables you to extract data from multiple sources, transform it into a usable format, and load it into your worksheet.

Why Use SQL Queries with Power Query?

SQL (Structured Query Language) is a powerful language used to manage and manipulate data in relational databases. By using SQL queries with Power Query, you can leverage the power of SQL to inquiry data from different Excel spreadsheets. This allows you to:

• Query data from multiple spreadsheets simultaneously
• Filter, sort, and group data with ease
• Perform complex data analysis tasks with ease
• Automate data refresh and update

Prerequisites

Before we dive into the tutorial, make sure you have the following:

• Microsoft Excel 2013 or later
• Power Query add-in (if you’re using Excel 2013)
• Two Excel spreadsheets: one with the data you want to inquiry, and another to load the results

Step 1: Enable Power Query

If you’re using Excel 2013, you’ll need to enable the Power Query add-in. To do this:

1. Go to File > Options > Add-ins
2. Check the box next to “Power Query” and click OK

Step 2: Create a New Query

To create a new query, follow these steps:

1. Go to the “Data” tab in your Excel worksheet
2. Click on “New Query” in the “Get & Transform Data” group
3. Choose “From Other Sources” > “From Microsoft Query”
4. Click “Connect” to open the Microsoft Query dialog box

Step 3: Connect to the External Spreadsheet

In the Microsoft Query dialog box:

1. Choose “Excel Files” as the data source
2. Click “Connect” to select the external spreadsheet file
3. Select the worksheet that contains the data you want to inquiry
4. Click “OK” to connect to the spreadsheet

Step 4: Write the SQL Query

In the Query Editor, you’ll see a formula bar at the top. This is where you’ll write your SQL query. For example:

SELECT *
FROM [Sheet1$]
WHERE [Region] = 'North'

This query selects all columns (*) from the “Sheet1” worksheet in the external spreadsheet, where the “Region” column is equal to ‘North’.

Step 5: Load the Results

To load the results of the query into your current worksheet:

1. Click “Load” in the “Home” tab
2. Choose a location to load the data (e.g., a new worksheet or a specific range)
3. Click “Load” to load the data

Step 6: Refresh the Data

To refresh the data and update the results:

1. Go to the “Data” tab
2. Click “Refresh All” in the “Get & Transform Data” group

Advanced Tips and Tricks

Using Parameters

You can use parameters to make your queries more dynamic. For example:

PARAMETERS Region = 'North'

SELECT *
FROM [Sheet1$]
WHERE [Region] = Region

This query uses a parameter called “Region” to filter the data. You can change the value of the parameter to inquiry different regions.

Joining Multiple Spreadsheets

You can use SQL joins to combine data from multiple spreadsheets. For example:

SELECT *
FROM [Sheet1$]
INNER JOIN [Sheet2$]
ON [Sheet1$].[OrderID] = [Sheet2$].[OrderID]

This query joins the “Sheet1” and “Sheet2” worksheets on the “OrderID” column.

Using Subqueries

You can use subqueries to inquiry data that meets specific conditions. For example:

SELECT *
FROM [Sheet1$]
WHERE [OrderID] IN (
  SELECT [OrderID]
  FROM [Sheet2$]
  WHERE [Total] > 100
)

This query selects all columns from “Sheet1” where the “OrderID” is in the list of order IDs from “Sheet2” where the total is greater than 100.

SQL Query	Description
SELECT *	Selects all columns from the specified table
FROM [Sheet1$]	Specifies the table to query
WHERE [Region] = ‘North’	Filters the data based on a specific condition
PARAMETERS Region = ‘North’	Defines a parameter to make the query more dynamic
INNER JOIN [Sheet2$]	Joins two tables based on a common column
ON [Sheet1$].[OrderID] = [Sheet2$].[OrderID]	Specifies the join condition
WHERE [OrderID] IN (…)	Filters the data based on a subquery

Conclusion

In this article, we’ve shown you how to use SQL queries via Power Query to inquiry a different Excel spreadsheet. By following these steps, you can easily extract and analyze data from multiple spreadsheets, making your data analysis tasks more efficient and accurate. Remember to practice and experiment with different SQL queries to unlock the full potential of Power Query.
