Question: I need to add a row to a spreadsheet using VBScript on a PC that does not have Microsoft Office installed.

I tried [`Set objExcel = CreateObject("Excel.Application")`]

Since Excel does not exist on the PC I cannot create this object.

Is there a way to modify a spreadsheet without Excel?

You might want to see [this question](https://stackoverflow.com/questions/151005/create-excel-xls-and-xlsx-file-from-c#151048). It's C# based, but should give you an insight into the techniques for accessing spreatsheets.
I believe the simple answer to your question is no because you need the Excel COM object which is only installed when Excel is installed. This used to be one of the real drawbacks of writing an Office app--the need for the entire application (Excel, Word or whatever) in order for an end-user to use it.
