I tried ScottF VB solution and got it to work. However I wanted to convert a multi-tab(workbook) excel file into a single .csv file.

This did not work, only one tab(the one that is highlighted when I open it via excel) got copied.

Is any one aware of a script that can convert a multi-tab excel file into a single .csv file?
