7 Ways To Combine Multiple Sheets In Excel Power Query

Combining multiple sheets in Excel can be a daunting task, especially when you're working with large datasets spread across different tabs. Thankfully, with Excel’s Power Query feature, this process becomes much more manageable and efficient. Power Query not only streamlines data importation but also enhances your overall workflow by providing tools for data transformation and cleansing. Here are seven effective ways to combine multiple sheets in Excel using Power Query.

Why Use Power Query for Combining Sheets?

Power Query enables you to easily connect, import, and manipulate data from various sources. When it comes to combining multiple sheets, Power Query offers several advantages:

• Automation: Once set up, the combination process can be refreshed automatically as data changes.
• User-friendly Interface: Its intuitive design allows even beginners to navigate and execute complex data manipulations.
• Powerful Transformation Tools: You can perform various data transformation operations before and after combining the sheets.

Let's dive into the specific techniques for combining multiple sheets using Power Query!

1. Load Multiple Sheets from One Workbook

To load data from multiple sheets within a single workbook, follow these steps:

1. Open Excel and navigate to the Data tab.

2. Select Get Data > From Other Sources > Blank Query.

3. In the Query Editor, go to the Home tab and click on Advanced Editor.

4. Input the following code to load all sheets from the workbook:

   let
       Source = Excel.CurrentWorkbook(),
       Sheets = Source{[Name="Sheet1"]}[Content],
       Combined = Table.Combine({Sheets})
   in
       Combined
   

5. Replace "Sheet1" with the actual sheet names you want to combine.

Important Note

<p class="pro-note">This approach is useful if you have predefined sheet names. If you have numerous sheets, consider using the next steps.</p>

2. Combine Sheets Dynamically

If you want to combine all sheets regardless of their names, you can do this dynamically:

1. Again, open a Blank Query.

2. Use the following code in the Advanced Editor:

   let
       Source = Excel.CurrentWorkbook(),
       Sheets = Table.SelectRows(Source, each [Kind] = "Sheet"),
       Combined = Table.Combine(Sheets[Content])
   in
       Combined
   

This script pulls in all sheets and combines their data into a single table.

Important Note

<p class="pro-note">Ensure that all sheets you intend to combine have the same structure (columns and data types) for best results.</p>

3. Merging Specific Sheets Only

You might only want to combine specific sheets based on certain criteria. Here’s how:

1. Open the Power Query Editor.

2. Follow the first two steps from above to load the sheets.

3. Utilize the filtering option to select the sheets of interest. Here’s an example code snippet:

   let
       Source = Excel.CurrentWorkbook(),
       Sheets = Table.SelectRows(Source, each [Name] = "Sheet1" or [Name] = "Sheet2"),
       Combined = Table.Combine(Sheets[Content])
   in
       Combined
   

4. Appending Data with Transformations

Sometimes, simply combining sheets isn’t enough. You may need to clean or transform the data during the merge:

1. Load the sheets using the methods discussed above.
2. Perform necessary transformations such as removing duplicates, changing data types, or adding calculated columns.
3. Finally, combine the transformed tables using Table.Combine.

Important Note

<p class="pro-note">Apply any transformations you need before combining to keep your data clean and concise.</p>

5. Using Parameters for Sheet Names

If you often need to combine different sheets, consider creating a parameter for sheet names:

1. Go to Manage Parameters in the Power Query Editor.
2. Create a new parameter to store the sheet name.
3. Use this parameter in your code to load and combine the sheets dynamically.

Example code:

let
    Source = Excel.CurrentWorkbook(),
    Sheets = Source{[Name=SheetNameParam]}[Content],
    Combined = Table.Combine({Sheets})
in
    Combined

6. Combining Sheets from Different Workbooks

Need to pull data from multiple workbooks? Here’s how to do it:

1. In Power Query, navigate to Get Data > From File > From Workbook.
2. Select the workbook and choose the sheets you want to combine.
3. Use Table.Combine to combine them similar to the previous methods.

Important Note

<p class="pro-note">Ensure all source workbooks are accessible and formatted similarly to avoid errors during combination.</p>

7. Automating Refresh for Combined Data

Once you’ve set up your queries and combined your sheets, it’s essential to ensure that your data stays up to date:

1. In Power Query, go to the File menu and select Options.
2. Under Data Load, select the option to refresh data on file open.
3. You can also set scheduled refreshes if working with Power BI.
