You have several Excel workbooks and you want to merge them into one file? This could be a troublesome and long process. But there are 6 different methods of how to merge existing workbooks and worksheets into one file. Depending on the size and number of workbooks, at least one of these methods should be helpful for you. Let’s take a look at them.
If you want to merge just a small amount of files, go with methods 1 or method 2 below. For anything else, please take a look at the methods 4 to 6: Either use a VBA macro, conveniently use an Excel-add-in or use PowerQuery (PowerQuery only possible if the sheets to merge have exactly the same structure).
Method 1: Copy the cell ranges
The obvious method: Select the source cell range, copy and paste them into your main workbook. The disadvantage: This method is very troublesome if you have to deal with several worksheets or cell ranges. On the other hand: For just a few ranges it’s probably the fastest way.
Method 2: Manually copy worksheets
The next method is to copy or move one or several Excel sheets manually to another file. Therefore, open both Excel workbooks: The file containing the worksheets which you want to merge (the source workbook) and the new one, which should comprise all the worksheets from the separate files.
- Select the worksheets in your source workbooks which you want to copy. If there are several sheets within one file, hold the Ctrl key and click on each sheet tab. Alternatively, go to the first worksheet you want to copy, hold the Shift key and click on the last worksheet. That way, all worksheets in between will be selected as well.
- Once all worksheets are selected, right click on any of the selected worksheets.
- Click on “Move or Copy”.
- Select the target workbook.
- Set the tick at “Create a copy”. That way, the original worksheets remain in the original workbook and a copy will be created.
- Confirm with OK.
One small tip at this point: You can just drag and drop worksheets from one to another Excel file. Even better: If you press and hold the Ctrl-Key when you drag and drop the worksheets, you create copies.

Method 3: Use the INDIRECT formula
The next method comes with some disadvantages and is a little bit more complicated. It works, if your files are in a systematic file order and just want to import some certain values. You build your file and cell reference with the INDIRECT formula. That way, the original files remain and the INDIRECT formula only looks up the values within these files. If you delete the files, you’ll receive #REF! errors.
Let’s take a closer look at how to build the formula. The INDIRECT formula has only one argument: The link to another cell which can also be located within another workbook.
- Copy the first source cell.
- Paste it into your main file using paste special (Ctrl + Alt + v ). Instead of pasting it normally, click on “Link” in the bottom left corner of the Paste Special window. That way, you extract the complete path. In our case, we have the following link:
- Now we wrap the INDIRECT formula around this path. Furthermore, we separate it into file name, sheet name and cell reference. That way, we can later on just change one of these references, for instance for different versions of the same file. The complete formula looks like this (please also see the image above):
Important – please note: This function only works if the source workbooks are open.
Method 4: Merge files with a simple VBA macro
You are not afraid of using a simple VBA macro? Then let’s insert a new VBA module:
- Go to the Developer ribbon. If you can’t see the Developer ribbon, right click on any ribbon and then click on “Customize the Ribbon…”. On the right hand side, set the tick at “Developer”.
- Click on Visual Basic on the left side of the Developer ribbon.
- Right click on your workbook name and click on Insert –> Module.
- Copy and paste the following code into the new VBA module. Position the cursor within the code and click start (the green triangle) on the top. That’s it!
'Merges all files in a folder to a main file.
Dim numberOfFilesChosen, i As Integer
Dim tempFileDialog As fileDialog
Dim mainWorkbook, sourceWorkbook As Workbook
Dim tempWorkSheet As Worksheet
Set mainWorkbook = Application.ActiveWorkbook
Set tempFileDialog = Application.fileDialog(msoFileDialogFilePicker)
'Allow the user to select multiple workbooks
tempFileDialog.AllowMultiSelect = True
numberOfFilesChosen = tempFileDialog.Show
'Loop through all selected workbooks
For i = 1 To tempFileDialog.SelectedItems.Count
'Open each workbook
Set sourceWorkbook = ActiveWorkbook
'Copy each worksheet to the end of the main workbook
For Each tempWorkSheet In sourceWorkbook.Worksheets
'Close the source workbook
Method 5: Automatically merge workbooks
The fifth way is probably most convenient:
Click on “Merge Files” on the Professor Excel ribbon.
Now select all the files and worksheets you want to merge and start with “OK”.
This procedure works well also for many files at the same time and is self-explanatory. Even better: Besides XLSX files, you can also combine XLS, XLSB, XLSM, CSV, TXT and ODS files.
Here is the whole process in detail:
Method 6: Use the Get & Transform tools (PowerQuery)
The current version of Excel 365 offers the “Get & Transform” tools to import data. These functions are very powerful and are supposed to replace the old “Text Import Wizard”. However, they have one useful feature: Import a complete folder of documents.
The requirements: The workbooks and worksheets you want to import have to be in the same format.
Please follow these steps for importing a complete folder of Excel files.
- Create a folder with all the documents you want to import.
- Usually it’s the fastest to just copy the folder path directly from the Windows Explorer. You still have the change to later-on select the folder, though.
- Within Excel, go to the Data ribbon and click on “Get Data”, “From File” and then on “From Folder”.
- Paste the previously copied path or select it via the “Browse” function. Continue with “OK”.
- If all files are shown in the following window, either click on “Combine” (and then on “Combine & Load To”) or on “Edit”. If you click on “Edit”, you can still filter the list and only import a selection of the files in the list. Recommendation: Put only the necessary files into your import folder from the beginning so that you don’t have to navigate through the complex “Edit” process.
- Next, Excel shows an example of the data based on the first file. If everything seems fine, click on OK. If your files have several sheets, just select the one you want to import, in this example “Sheet1”. Click on “OK”.
- That’s it, Excel now imports the data and inserts a new column containing the file name.

Next step: Merge multiple worksheets to one combined sheet
After you have combined many Excel workbooks into one file, usually the next step is this: Merge all the imported sheets into one worksheet.
