Compile Numbers from Multiple Excel Sheets Easily

If you find yourself working with multiple Excel files, each containing valuable data, you'll know the challenge of consolidating this information can be daunting. Whether you're pulling together financial data, survey results, or inventory lists, combining data from various spreadsheets can save time and reduce errors. This guide walks you through the steps to compile numbers from multiple Excel sheets easily using Microsoft Excel's features.

Step 1: Understanding Your Data

Before you begin merging data, it’s critical to:

• Know which sheets contain the data you need.
• Identify if your data has consistent headers or if adjustments will be necessary.
• Check if the data formats are compatible across sheets (e.g., date formats, currency).

Consistent structure across sheets will streamline the process. If sheets have different structures, you might need to manually adjust or standardize the data before merging.

Step 2: Consolidation Using Power Query

Power Query is Excel’s powerful tool for data transformation and loading. Here’s how to use it:

1. Navigate to the Data Tab: Select “Get Data” and then “From File” followed by “From Workbook.”
2. Choose Workbooks: Navigate to the first Excel workbook, select it, and click “Import.”
3. Select Sheets: In the Navigator pane, select all sheets you want to consolidate. Use Ctrl+Click or Shift+Click to choose multiple sheets.
4. Create Table from Selection: Click “Combine” and then “Combine and Edit.” Excel will open the Power Query Editor.
5. Configure the Merge: In the Power Query Editor:
   • Select the columns you want to combine.
   • Click “Merge Columns” if you need to combine them into one column.
6. Apply Transformations: Adjust the data if necessary (e.g., change column names, remove unnecessary columns).
7. Load to Excel: Click “Close & Load” to bring the data into your current Excel file.

💡 Note: Power Query is available in Excel for Microsoft 365, Excel 2016, and later versions. If you're using an older version, consider updating to access this feature.

Step 3: Merging Data Manually

If Power Query isn’t an option, here’s how to manually merge data:

1. Create a New Workbook: Open a new Excel workbook to serve as your consolidation workbook.
2. Set Up the Structure: Create headers in the new workbook that match the headers from the sheets you wish to consolidate.
3. Copy Data:
   • Open each workbook and copy the relevant data.
   • Paste the data below the headers in the consolidation workbook.
4. Align Data: Ensure the data aligns correctly with the headers.
5. Remove Duplicates: If you have data from multiple sheets that might duplicate, use Excel’s “Remove Duplicates” function.

🔍 Note: For large datasets, manual merging can be time-consuming and error-prone. Consider using automation tools or Power Query to save time.

Step 4: Using VLOOKUP or Index-Match for Partial Merges

If your sheets share a common identifier (like a product ID or employee ID), you can merge specific columns from multiple sheets into one sheet:

📚 Note: INDEX-MATCH is more versatile than VLOOKUP, especially when merging data from various sources with differing column structures.

Step 5: Automating the Merge with Macros

For those comfortable with VBA, automating the data consolidation can significantly speed up the process:

1. Open the VBA Editor: Press Alt + F11 in Excel.
2. Create a New Module: Click “Insert” and select “Module.”
3. Write the VBA Code: Here’s a basic example:

Sub MergeSheets()
    Dim ws As Worksheet, wks As Worksheet
    Dim lastRow As Long, lastCol As Long

' Loop through all sheets
For Each ws In ThisWorkbook.Sheets
    If ws.Name <> "Summary" Then
        lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
        lastCol = ws.Cells(1, ws.Columns.Count).End(xlToLeft).Column
        Set wks = ThisWorkbook.Sheets("Summary")

        ' Copy data from each sheet to the Summary sheet
        ws.Range(ws.Cells(2, 1), ws.Cells(lastRow, lastCol)).Copy Destination:=wks.Cells(wks.Rows.Count, 1).End(xlUp).Offset(1, 0)
    End If
Next ws


End Sub

4. Save and Run the Macro: Save the workbook as a Macro-Enabled Workbook and run the macro when needed.

When merging data from multiple Excel sheets, ensure the process is streamlined for efficiency. Here's a recap of the key points:

• Understand Your Data: Know the structure and consistency of your sheets before merging.
• Power Query: Use Power Query for a seamless, automated merge across multiple sheets.
• Manual Merging: If Power Query isn't available, manual merging can still work, albeit with more effort.
• VLOOKUP/INDEX-MATCH: Efficient for partial data consolidation based on a common identifier.
• VBA Macros: Automate repetitive tasks for frequent consolidation needs.

By following these steps, you'll be able to merge data from multiple Excel sheets efficiently, leading to more accurate analysis and reporting.

Can I merge sheets from different Excel files?

+

Yes, with Power Query, you can merge sheets from different files by selecting multiple files during the data import process.

What if my sheets have different formats or structures?

+

You’ll need to standardize your data before merging. This might involve manual adjustments or using Excel formulas to transform data to match.

Do I need special skills for VBA macros?

+

Some familiarity with VBA can be helpful, but basic recording and running macros can be done without in-depth programming knowledge.
