VBA: How to handle inconsistent data types when automating Excel with late binding?
I'm writing unit tests and Can someone help me understand I'm working on an Excel automation project using VBA and late binding, specifically targeting Excel 2016....... I've encountered an scenario where I'm trying to copy data from one worksheet to another, but I keep getting a 'Type mismatch' behavior. The code looks something like this: ```vba Dim xlApp As Object Dim xlWorkbook As Object Dim xlSourceSheet As Object Dim xlTargetSheet As Object Set xlApp = CreateObject("Excel.Application") Set xlWorkbook = xlApp.Workbooks.Open("C:\path\to\your\file.xlsx") Set xlSourceSheet = xlWorkbook.Sheets("SourceSheet") Set xlTargetSheet = xlWorkbook.Sheets("TargetSheet") Dim rowCount As Long rowCount = xlSourceSheet.Cells(xlSourceSheet.Rows.Count, 1).End(-4162).Row ' -4162 is xlUp Dim i As Long For i = 1 To rowCount xlTargetSheet.Cells(i, 1).Value = xlSourceSheet.Cells(i, 1).Value Next i xlWorkbook.Save xlApp.Quit Set xlApp = Nothing ``` I'm trying to copy data from column A of the source sheet to column A of the target sheet. The question arises when the source sheet contains mixed data types (numbers, text, and dates). I attempted to explicitly convert the cells using `CStr`, `CInt`, and `CDate`, but the behavior continues in some cases. I also tried wrapping the assignment in an behavior handler, but I still can’t identify which specific row or value is causing the scenario. Here's the behavior message I receive: ``` Runtime behavior '13': Type mismatch ``` Is there a better way to handle this scenario, especially when dealing with inconsistent data types? Any help would be appreciated! What am I doing wrong? This is part of a larger service I'm building. This is part of a larger service I'm building. This is my first time working with Vba stable. Thanks in advance!
