Manipulate/copy .CSV data, without opening the file?

Question

I\'m trying to optimize some code that takes some test data stored in CSV files does some analysis and copies their data into an excel sheet. This code is often run on hundreds

Answer 1

I would open them as text rather than workbooks:

Sub ReadCSV()
    Dim MyString As String
    Open "C:\path\text.csv" For Input As #1 ' Open file for input. 
    Do While Not EOF(1) ' Loop until end of file.
        Line Input #1, MyString ' Read a line into variable
        Debug.Print MyString ' Print data to the Immediate window.
    Loop
    Close #1 ' Close file.

End Sub

This will be much faster than opening as a workbook
