Coldfusion Spreadsheet cell formatting

Coldfusion Spreadsheet cell formatting

I need to generate excel spreadsheet with coldfusion 10 from a query. So
far its working fine except the headers of the table. They are dynamically
generated [month Year] December 2012. When I add a header column I get it
in the date format like '01/12/2013'. There are other types of date
formatting and other types of cell formatting. How do I force a cell to
format as a string. Kind of when you add single quotation.
This is my code:
<cfset VARIABLES.vcFilename = "billtotals_" & DateFormat(Now(),
"yyyymmdd") & "-" & TimeFormat(Now(), "HHmmss") & ".xls">
<cfset VARIABLES.sheet = SpreadSheetNew( "Summary" )>
<cfset VARIABLES.columns =
arrayToList(GetBillPremTotals.getMeta().getColumnLabels())>
<cfset SpreadSheetAddRow( VARIABLES.sheet,VARIABLES.columns)>
<cfset format1 = StructNew()>
<cfset format1.bold = "true">
// tried this just for kicks doesn't work <cfset format1.dataformat = "'">
<cfset SpreadsheetFormatRow(VARIABLES.sheet, format1, 1)>
<cfset SpreadSheetAddRows(VARIABLES.sheet,GetBillPremTotals)>
<cfset SpreadSheetAddRows(VARIABLES.sheet,GetBillPremGrandTotals)>
<cfset VARIABLES.sheetAsBinary = SpreadSheetReadBinary(VARIABLES.sheet)>
<cfheader name="Content-Disposition" value="attachment;
filename=#Chr(34)##VARIABLES.vcFilename##Chr(34)#">
<cfcontent type="application/msexcel" variable="#VARIABLES.sheetAsBinary#"
reset="true">
Thank you in advance, Gena
