Error when diffing Excel files (new file has one additional worksheet)

Hello!

When diffing an excel file with its previous version, I got

Windows Scripting Host
Skript: ...Diff-Scripts\diff-xls.js
Zeile/Line 145
Fehler: Index außerhalb des gültigen Bereichs
(Error: Index out of range)
Code: 800A0009
Quelle: Laufzeitfehler in Microsoft JScript
(Source: Runtime error in Microsoft JScript)

The relevant portion is

// Mark differences in sNewDoc red
var length = objNewWorkbook.Worksheets.Count;
for (var i = 1; i <= length; i++)
{
    var objBaseWorksheet = objBaseWorkbook.Worksheets(i); <<<< line 145
    var objNewWorksheet = objNewWorkbook.Worksheets(i);

and in this case the new version has an additional worksheet which base does not have,
so last i = length (from objNewWorkbook) is out of range for objBaseWorkbook

I don't know this language and excel well enough to suggest a fix - who can repair this?

(I got this report from a coworker using 1.8.11, same here with 1.9.2)
