There are many ways to do that. As I assume adding VBA code to each workbook is no option, you'll best use a "master" Excel file containing the code. Or VB Script, or PowerShell.
How are you getting the list of workbooks to process? All workbooks sitting in a specific folder, for example?

Qlemo, yes all workbooks in same folder.

This PowerShell script will assume the workbooks are located in C:\Temp\EE\WorkBooks, and the results should also be stored there as «WorkbooName»-«SheetName».csv
$excel = New-Object -ComObject excel.application
$excel.Visible = $false

foreach ($wbFile in get-childitem 'C:\temp\ee\workBooks\*.xls*') {
  $wbs = $excel.Workbooks.Open($wbFile.FullName)
  foreach ($ws in $wbs.WorkSheets) {
    $ws.SaveAs($wbFile.Directoryname + '\' + $wbFile.BaseName + '-' + $ws.Name + ".csv", 23)
