How to use Power Query to integrate many CSV files into one?

We demonstrate how Power Query can be used to import data from different sources and then combine and merge tables in accordance with your formatting preferences in How to Use Excel Power Query for Beginners.

The nicest part of this is that not a single line of code will need to be written. We’ll now demonstrate how to import, combine, and prepare numerous CSV files in the manner of your choice.

Step1. Navigate to the folder containing all of your CSV files. Otherwise, make a folder that just contains the CSV files you want to combine.

Step2, Select Data > Get Data > From File > From Folder from within an open Excel worksheet.

Step3. Click “Open” after selecting the folder containing the CSV files.

Step4. Decide between “Combine & Transform Data,” “Combine & Load,” or “Combine & Load To…” from the “Combine” drop-down menu. The first option, which puts all CSV files into the “Power Query Editor” so you may arrange and filter the data however you like, is what we advise.

Step5. Click “OK” to continue after leaving the “Combine Files” window’s default selection alone.

Step6. If the folder contains other files, turn on the filter in the “Source.Name” column in the “PowerQuery Editor” box to remove each additional file.

Step7. Click on the header of the column you want to change the data formatting for, and then select “Data Type”. You can convert some values, for instance, to “Currency” or “Date” forms.

Step8. If you want to maintain unique values, choose the “unique identifier” column, and then choose Remove Rows > Remove Duplicates.

Step9. To close and load your work after editing it, select Home > Close & Load or “Close & Load To…” This depends on whether or not you want to import your data as a “PivotTable” or “PivotTable chart” to a new sheet or an existing sheet as a table. Here, I’ll choose option 1 because I want to import it as a table onto a different sheet.

How to use Command Prompt to Merge Multiple CSV files into One Excel?

To ensure that the Command Prompt tool, often known as CMD, functions correctly, keep all of the CSV files you plan to combine into one Excel file in a single folder.

Step1. When you right-click the folder containing your CSV files while holding down Shift, choose “Copy path” from the menu. This feature will also be accessible in Windows 10’s File Explorer’s Home tab.

Step2. For the “Run” box to appear, press Windows+R. To open the Command Prompt, enter “cmd” and then press “OK”.

Step3. In the “Command Prompt” window, type “cd” and then a space. Press Ctrl + V to paste the folder path. Drag the folder into the “Command Prompt” window to complete the task more quickly. To carry out the command, press “Enter”.

Step4. The command line should now show the folder’s updated path.

Step5. In the command line, type “copy *.csv merged-csv-files.csv” following the folder path. Once finished, hit Enter. Please take note that you can change the filename “merged-csv-files.csv” to one of your choosing.

Step6. Then, navigate to the folder holding your original files after closing the “Command Prompt” window. A file with the name “merged-csv-files.csv” or the name you specified should now be visible.

The techniques you have seen up to this point work with Excel 2019 and 365 as well as Windows 10 and newer versions.
