One-Click Data Validation with VBA: Lookup Value Column (Sheet2) Matches Value Column (Sheet1)
In this article, we will explore how to create a one-click data validation solution using VBA in Microsoft Excel. This solution will enable you to check if the values in a column in Sheet2 match the values in a column in Sheet1. We will cover the key concepts and provide detailed context on the topic.

Introduction
Data validation is an essential feature in Excel that ensures the accuracy and consistency of data entered into a worksheet. With VBA, you can create custom data validation rules that go beyond Excel's built-in features. In this example, we will create a one-click data validation solution that checks if the values in a column in Sheet2 match the values in a column in Sheet1.
Prerequisites
Before we begin, it is assumed that you have a basic understanding of VBA programming and data validation in Excel. You do not need to be an expert in VBA, but some programming knowledge is required. Additionally, we will be working with two sheets in this example: RawData and DataValidation. The RawData sheet contains the raw data, and the DataValidation sheet contains the data that we will validate.
The VBA Code
The following VBA code implements the one-click data validation solution. The code checks if the values in column A in Sheet2 match the values in column A in Sheet1. If a match is found, the code sets the data validation for the corresponding cell in Sheet2 to "Yes". If no match is found, the data validation is set to "No".
Sub OneClickDataValidation()
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Dim rng1 As Range
Dim rng2 As Range
Dim c As Range
Dim i As Long
' Set references to the worksheets
Set ws1 = ThisWorkbook.Sheets("Sheet1")
Set ws2 = ThisWorkbook.Sheets("Sheet2")
' Set references to the ranges
Set rng1 = ws1.Range("A1:A" & ws1.Cells(ws1.Rows.Count, "A").End(xlUp).Row)
Set rng2 = ws2.Range("A1:A" & ws2.Cells(ws2.Rows.Count, "A").End(xlUp).Row)
' Loop through each cell in column A in Sheet2
For Each c In rng2
' Check if the value in the current cell in Sheet2 matches any value in column A in Sheet1
i = Application.Match(c.Value, rng1, 0)
' If a match is found, set the data validation for the current cell in Sheet2 to "Yes"
If Not IsError(i) Then
c.Offset(0, 1).Validation.Add Type:=xlValidateList, Formula1:="Yes"
End If
' If no match is found, set the data validation for the current cell in Sheet2 to "No"
If IsError(i) Then
c.Offset(0, 1).Validation.Add Type:=xlValidateList, Formula1:="No"
End If
Next c
End Sub
How to Use the Code
To use the code, follow these steps:
- Open a new or existing Excel workbook.
- Create two sheets: RawData and DataValidation.
- Enter the raw data in the RawData sheet.
- Enter the data to be validated in the DataValidation sheet.
- Press Alt + F11 to open the VBA editor.
- Insert a new module.
- Copy and paste the VBA code into the module.
- Close the VBA editor.
- Run the OneClickDataValidation macro.
