How To Combine Multiple Excel Files Into One

Combining multiple Excel files into one can be a time-consuming task, especially if you have a large number of files to merge. As a technical enthusiast, I often find myself needing to aggregate data from various sources, and mastering this process has been a game-changer for me. In this article, I’ll guide you through the step-by-step process of merging Excel files, and I’ll also share some tips and tricks that have helped me streamline this task.

Step 1: Organizing Your Excel Files

Before diving into the merging process, it’s essential to organize your Excel files. Create a dedicated folder for the files you want to combine. This helps to keep track of the files and simplifies the process of selecting them for merging.

Step 2: Opening Excel and Creating a New Workbook

Open Microsoft Excel and create a new workbook. This will be the file where you consolidate all the data from the multiple Excel files. To keep things organized, consider naming the sheets based on the original file names or data sources.

Step 3: Importing Data from Multiple Excel Files

To import data from other Excel files, navigate to the “Data” tab and select “Get Data” or “From File” (the options may vary slightly based on your Excel version). Choose “From Workbook” and then browse to the folder containing your Excel files. Select the files you want to merge, and Excel will import them one by one into the new workbook.

Step 4: Appending Data

Once the data from the Excel files is imported, you may need to append it together. Excel provides options to append data from multiple sources, allowing you to combine them seamlessly. Navigate to the “Data” tab, choose “Get Data”, and select “Append Queries”. Follow the prompts to combine the data from the imported Excel files into a single table.

Step 5: Cleaning and Formatting

After merging the data, it’s common to encounter inconsistencies in formatting or data structure. Take the time to clean and format the combined data to ensure uniformity. This may involve removing duplicates, adjusting column formats, and ensuring consistent naming conventions.

Additional Tips:

  • Consider using Excel’s Power Query feature for more advanced data manipulation during the merging process.
  • Save the combined workbook with a clear and descriptive file name for easy reference in the future.


Combining multiple Excel files into one can be a powerful skill, especially when dealing with data aggregation or reporting. As a technical enthusiast, mastering this process has significantly improved my efficiency in handling diverse datasets. By following these steps and incorporating some best practices, you’ll be better equipped to tackle the challenge of merging Excel files with confidence.
