**Automatically and Efficiently Unifying Multiple .xlsx Files in the Same Folder**

Introduction

Are you tired of manually copying and pasting data from multiple .xlsx files into a single spreadsheet? This tedious process can be time-consuming and prone to errors, especially when dealing with hundreds of files like monthly securities transactions for past decades. In this article, we will explore a more efficient and automated way to unify multiple .xlsx files in the same folder using Microsoft Excel.

Presuppositions

For the sake of simplicity, let's assume you have two .xlsx files in the same folder that you want to unify. We will use these files as a starting point to demonstrate the process.

Example Files

Suppose we have two .xlsx files:

transactions_2022.xlsx
transactions_2023.xlsx

Each file contains a table with the following columns:

Column A	Column B	Column C
Date	Transaction ID	Amount

Method 1: Using Power Query

Microsoft Excel's Power Query feature allows you to easily combine multiple tables from different .xlsx files into a single table. Here's how to do it:

Step 1: Enable Power Query

To access Power Query, go to the "Data" tab in the ribbon and click on "New Query" > "From File" > "From Workbook". Select the first .xlsx file (transactions_2022.xlsx) and click "Load".

Step 2: Load the Second File

Repeat the process in Step 1, but this time select the second .xlsx file (transactions_2023.xlsx). Power Query will load the data from both files into separate tables.

Step 3: Merge the Tables

To merge the tables, go to the "Home" tab in the Power Query Editor and click on "Merge Queries". Select the two tables and choose the common column (e.g., "Transaction ID") to merge on.

Step 4: Load the Combined Table

Once the tables are merged, click on "Load" to load the combined table into a new worksheet.

Method 2: Using VBA Macros

If you prefer to use VBA macros, you can write a script to automate the process of unifying multiple .xlsx files. Here's an example code:

Sub UnifyExcelFiles()
&#39; Declare variables
Dim ws As Worksheet
Dim lastRow As Long
Dim i As Long
Dim j As Long

&#39; Set the folder path
Dim folderPath As String
folderPath = &quot;C:\Path\To\Folder&quot;

&#39; Set the file extension
Dim fileExtension As String
fileExtension = &quot;.xlsx&quot;

&#39; Loop through all files in the folder
For i = 1 To 2
    &#39; Set the file path
    Dim filePath As String
    filePath = folderPath &amp; &quot;\&quot; &amp; &quot;transactions_&quot; &amp; i &amp; fileExtension
    
    &#39; Open the file
    Workbooks.Open filePath
    
    &#39; Get the last row of the worksheet
    lastRow = ActiveSheet.Cells(Rows.Count, &quot;A&quot;).End(xlUp).Row
    
    &#39; Loop through all rows in the worksheet
    For j = 1 To lastRow
        &#39; Copy the
        Rows(j).Copy
        
        &#39; Paste the row into the next available row in the destination worksheet
        ActiveSheet.Cells(Rows.Count, &quot;A&quot;).End(xlUp).Offset(1, 0).Paste
        
        &#39; Clear the clipboard
        Application.CutCopyMode = False
    Next j
    
    &#39; Close the file
    ActiveWorkbook.Close False
Next i

End Sub

Method 3: Using Excel's Consolidate Feature

Excel's Consolidate feature allows you to combine data from multiple worksheets into a single worksheet. Here's how to use it:

Step 1: Select the Range

Select the range of cells that you want to consolidate.

Step 2: Go to the Data Tab

Go to the "Data" tab in the ribbon.

Step 3: Click on Consolidate

Click on "Consolidate" in the "Data Tools" group.

Step 4: Select the Function

Select the function that you want to use (e.g., SUM, AVERAGE, COUNT).

Step 5: Select the Source Data

Select the source data that you want to consolidate.

Step 6: Click on OK

Click on "OK" to consolidate the data.

Conclusion

Unifying multiple .xlsx files in the same folder can be a tedious and time-consuming process, but it doesn't have to be. By using Power Query, VBA macros, or Excel's Consolidate feature, you can automate the process and save time.
