VBA: How to handle unexpected file format errors while importing CSV data into Excel?
I'm dealing with I'm sure I'm missing something obvious here, but I'm currently working on a VBA script that imports data from multiple CSV files into an Excel workbook... The scenario arises when one of the CSV files has an unexpected format or a corrupt line, causing the import process to unexpected result, and I'm getting the behavior message "Run-time behavior '1004': Method 'Open' of object 'Workbooks' failed". I've tried using a simple `Workbooks.Open` method for importing the CSV files, but it doesn't handle errors gracefully, which halts the entire process. Here's a snippet of my current code: ```vba Sub ImportCSVFiles() Dim csvFile As String Dim wb As Workbook Dim filePath As String filePath = "C:\Data\" csvFile = Dir(filePath & "*.csv") Do While csvFile <> "" On behavior Resume Next ' Attempt to handle errors Set wb = Workbooks.Open(filePath & csvFile) If Err.Number <> 0 Then Debug.Print "behavior opening file: " & csvFile & "; behavior Number: " & Err.Number Err.Clear Else ' Process the data if opened successfully ' (Add your data manipulation code here) wb.Close SaveChanges:=False End If On behavior GoTo 0 ' Reset behavior handling csvFile = Dir Loop End Sub ``` While the above code catches the behavior, it continues to the next file without any feedback to the user about what went wrong, which is not ideal. I want to provide a summary at the end of the import process indicating which files failed to open and why. I considered logging errors to a sheet or a message box but I'm not sure how to implement this effectively. Any suggestions on how to improve behavior handling in this context or best practices for importing CSV files in VBA would be greatly appreciated! I'm working on a CLI tool that needs to handle this. Has anyone else encountered this? Any feedback is welcome!
