How to pull data from multiple workbooks

Tgunnz5 

To pull data from the same cell across multiple workbooks/files that are labeled by date, you can use a combination of Excel functions and VBA to automate the process.

Here is a step-by-step guide to achieve this:

Step 1: Prepare Your Master Workbook

1. Create a new sheet for the data extraction.
2. List all the dates for the year in column A (e.g., A1 has the header "Date", and A2 to A366 list all dates from 01-Jan-2024 to 31-Dec-2024).

Step 2: Use VBA to Automate Data Extraction

You will need a VBA macro to loop through the dates, open the corresponding workbook, and extract the desired cell value.

1. Press Alt + F11 to open the VBA editor.
2. Insert a new module:

• Right-click on any existing module or the "VBAProject (YourWorkbookName)" > Insert > Module.

3. Paste the following VBA code into the module:

Vba Code is untested, please backup your file first.

Sub ExtractDataFromWorkbooks()
    Dim ws As Worksheet
    Dim dataSheet As Worksheet
    Dim cellValue As Variant
    Dim dateCell As Range
    Dim filePath As String
    Dim dateStr As String
    Dim sourceCell As String
    Dim i As Integer
    
    ' Set the worksheet variables
    Set ws = ThisWorkbook.Sheets("Sheet1") ' Change to your sheet name
    sourceCell = "B2" ' Change to the cell you want to extract data from

    ' Loop through each date in the list
    For i = 2 To 366 ' Adjust based on the number of rows you have
        dateStr = Format(ws.Cells(i, 1).Value, "yyyymmdd") ' Format the date to match your file naming convention
        filePath = "C:\YourFolderPath\" & dateStr & ".xlsx" ' Change the folder path as needed

        ' Check if the file exists
        If Dir(filePath) <> "" Then
            ' Open the workbook
            Application.Workbooks.Open (filePath)
            
            ' Set the data sheet (assuming it's the first sheet in the workbook)
            Set dataSheet = Workbooks(dateStr & ".xlsx").Sheets(1)
            
            ' Get the value from the specified cell
            cellValue = dataSheet.Range(sourceCell).Value
            
            ' Close the workbook without saving
            Workbooks(dateStr & ".xlsx").Close SaveChanges:=False
            
            ' Write the cell value to the master workbook
            ws.Cells(i, 2).Value = cellValue
        Else
            ' If the file doesn't exist, write an error message
            ws.Cells(i, 2).Value = "File not found"
        End If
    Next i
End Sub

Step 3: Adjust the VBA Code to Your Needs

• Change "Sheet1" to the name of your sheet in the master workbook.
• Update sourceCell to the cell address from which you want to extract data (e.g., "B2").
• Set the filePath to the correct folder path where your daily files are stored (e.g., "C:\YourFolderPath\").
• Adjust the loop range if you have a different number of rows for dates (e.g., For i = 2 To 366 if you have a header in row 1).

Step 4: Run the Macro

1. Press Alt + F8 to open the Macro dialog box.
2. Select ExtractDataFromWorkbooks and click Run.

Tips for Future Use

• Keep the folder structure and naming convention consistent year after year.
• Ensure your daily files are named with a consistent format matching the date format in your master sheet.

By using this method, you can automate the extraction of data from multiple workbooks without manually opening each file, making it easier to maintain and use your template year after year.
