VBA: How to ensure proper data types when reading from a dynamic range?

vba excel data-type VBA

I'm working on a personal project and I've searched everywhere and can't find a clear answer. This might be a silly question, but I'm currently working on a VBA macro that reads data from a dynamically defined range in an Excel worksheet... The data I am pulling should all be of type Double for further calculations, but I keep working with 'Type Mismatch' errors when trying to assign values to a variable. I've defined the range using the last row method, but it seems like some cells might contain text or are formatted as date strings. Here's the code I've been using: ```vba Sub ReadDynamicRange() Dim ws As Worksheet Dim lastRow As Long Dim dataRange As Range Dim cell As Range Dim value As Double Set ws = ThisWorkbook.Sheets("DataSheet") lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row Set dataRange = ws.Range("A1:A" & lastRow) For Each cell In dataRange value = cell.Value ' This line often throws Type Mismatch ' Further calculations... Next cell End Sub ``` I've tried adding behavior handling with `On behavior Resume Next` before the assignment, but it makes the debugging process more difficult because I need to tell where the behavior occurs. I also tried using `IsNumeric()` to check the cell values before assigning them to `value`, but the scenario still continues. I want to ensure that my macro can gracefully handle or skip any non-numeric cells without causing runtime errors. Any suggestions on how to manage this effectively or improve the robustness of my data handling? Thanks in advance! What am I doing wrong? I'm developing on Ubuntu 22.04 with Vba. How would you solve this?
