Excel Reader Corrupts the Excel File

[Anonymous]

I'm successfully reading data from an Excel file using the Excel Reader.  However, as soon as the read is done, the file Excel seems to be corrupted and I can no longer open it (programatically or by hand).

Any ideas what is going on?

The parent ExcelDoc:

Rule okToOverwrite? As Boolean = False
Rule OutputDocPath As String = ProjectLocation() + "\DocumentComponents\Specifications\"
Rule OutputDocument As String = TemplateDocPath + TemplateFileName
Rule OutputFileName As String = "CP UI Specification.xlsx"
Rule SaveAsFormat As String = "Excel"
Rule ShowReport? As Boolean = False
Rule TemplateDocPath As String = ProjectLocation() + "\DocumentComponents\Specifications\"
Rule templateDocument As String = TemplateDocPath + TemplateFileName
Rule TemplateFileName As String = "CP UI Specification.xlsx"

The child ExcelDataReader:

Parameter Rule Row As Integer = 1
Rule ReadRange As String = "A" + stringValue(Row) + ":I" + stringValue(Row)
Rule Sheet As String = "Mapping"
Rule Range = ReadRange
Rule DependentParts As List = {}
