How to Merge Multiple Vendor Price Lists into One Clean Sheet

If you work with multiple suppliers, you've probably faced the nightmare of dozens of vendor price lists—each with different formats, headers, and currencies.
Manually cleaning and merging these files is error-prone and can take days of effort.

In this guide, we'll show you step-by-step methods to combine multiple vendor sheets into one clean, structured Excel file.

---

🚨 Why Vendor Price Lists Are So Messy

• Different column names: Price vs Unit Cost vs Cost Price.
• Mixed currencies: USD, EUR, GBP, INR.
• Inconsistent date formats.
• Extra blank rows, merged cells, and random notes.
• Duplicate products across vendors.

Without cleanup, you can't analyze, compare, or even load this data into your ERP/POS system.

🛠 Method 1: Manual Copy + Paste (❌ Painful)

The most common approach is copy-paste:

1. Open each vendor file.
2. Copy the rows.
3. Paste them into a master sheet.

The problem?

• Headers don't match.
• Formatting breaks.
• Duplicates creep in.
• Impossible to scale if you manage 10+ vendors.

🛠 Method 2: Power Query (Semi-Automated)

Power Query is a powerful built-in tool in Excel:

1. Go to Data → Get Data → From Folder.
2. Load all vendor files from a single folder.
3. Use Power Query to standardize headers and formats.
4. Append them into one clean sheet.

✔️ Handles multiple files.
❌ Requires setup for each schema change.

🛠 Method 3: VBA/Macros (Advanced Users)

If vendors follow similar formats, VBA scripts can automate merging:

Sub MergeVendorFiles()
    Dim ws As Worksheet
    Dim wsMaster As Worksheet
    Dim rng As Range
    Dim pasteRow As Long

    Set wsMaster = ThisWorkbook.Sheets("Master")
    pasteRow = 2

    For Each ws In ThisWorkbook.Worksheets
        If ws.Name <> "Master" Then
            ws.Range("A2:A1000").EntireRow.Copy
            wsMaster.Cells(pasteRow, 1).PasteSpecial xlPasteValues
            pasteRow = wsMaster.Cells(Rows.Count, 1).End(xlUp).Row + 1
        End If
    Next ws
End Sub

✔️ Automates merging.
❌ Breaks easily if vendor formats differ.
