Convert XLS to CSV on command line

:: For UTF-8 works for Microsoft Office 2016 and higher!

Try this code:

if WScript.Arguments.Count < 2 Then
    WScript.Echo "Please specify the source and the destination files. Usage: ExcelToCsv <xls/xlsx source file> <csv destination file>"
    Wscript.Quit
End If

csv_format = 62

Set objFSO = CreateObject("Scripting.FileSystemObject")

src_file = objFSO.GetAbsolutePathName(Wscript.Arguments.Item(0))
dest_file = objFSO.GetAbsolutePathName(WScript.Arguments.Item(1))


Dim oExcel
Set oExcel = CreateObject("Excel.Application")

Dim oBook
Set oBook = oExcel.Workbooks.Open(src_file)

oBook.SaveAs dest_file, csv_format

oBook.Close False
oExcel.Quit

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?

Create a TXT file on your desktop named "xls2csv.vbs" and paste the code:

Dim vExcel
Dim vCSV
Set vExcel = CreateObject("Excel.Application")
Set vCSV = vExcel.Workbooks.Open(Wscript.Arguments.Item(0))
vCSV.SaveAs WScript.Arguments.Item(0) & ".csv", 6
vCSV.Close False
vExcel.Quit

Drag a XLS file to it (like "test.xls"). It will create a converted CSV file named "test.xls.csv". Then, rename it to "test.csv". Done.

All of these answers helped me construct the following script which will automatically convert XLS* files to CSV and vice versa, by dropping one or more files on the script (or via command line). Apologies for the janky formatting.
