CFspreadsheet adding a % to format a column - coldfusion

Question

I am using CF10 and trying to add a % sign to a spreadsheet.
I am having an issue with adding a % sign on my 5th column entries. (Only the entries starting the second row (not the header) and not the blank cells when the query is done running.
<cftry>
<cfset objSpreadsheet = SpreadsheetNew()>
<cfset assocRows = ''>
<!--- Create and format the header row. --->
<cfset SpreadsheetAddRow( objSpreadsheet, "Associate Name,Location,Checklists Generated by Associate,Checklists Generated by Selected Location(s),Associate Percentage of Location Total" )>
<cfset rowNumber = 1 />
<cfoutput query="GetEmployeeInfo">
<cfset rowNumber++ />
<cfset rowList = "'#(rnA eq 1)?assoc_name:''#','#(rnl eq 1)?trans_location:''#','#checklistsByAssocLoc#','#assocChecklistsByLoc#','#DecimalFormat(totalChecklistsByAssocLocPct)#'">
<!--- Make list of rows --->
<cfif (rnA eq 1)>
<cfset assocRows = ListAppend(assocRows, rowNumber)>
</cfif>
<cfset SpreadsheetAddRow( objSpreadsheet, rowList)>
<cfif rnTotAssoc EQ 1>
<cfset rowNumber++ />
<cfset rowList = "'Associate Total','','#totalChecklistsByAssoc#','#totalAssocChecklistsByAllFilteredLoc#','#DecimalFormat(totalChecklistsByLocPct)#'" >
<cfset SpreadsheetAddRow( objSpreadsheet, rowList )>
</cfif>
</cfoutput>
<cfset SpreadSheetSetColumnWidth(objSpreadsheet,1,25)>
<cfset SpreadSheetSetColumnWidth(objSpreadsheet,2,25)>
<cfset SpreadSheetSetColumnWidth(objSpreadsheet,3,25)>
<cfset SpreadSheetSetColumnWidth(objSpreadsheet,4,25)>
<cfset SpreadSheetSetColumnWidth(objSpreadsheet,5,25)>
<!--- Move the line here --->
<cfset SpreadsheetFormatRow( objSpreadsheet, {bold=true, textwrap="true", alignment="center"}, 1 )>
<cfloop list="#assocRows#" index="i">
<cfset SpreadsheetFormatCell(objSpreadsheet, {'bold' : 'true'}, i, 1)>
</cfloop>
<cfheader name="Content-Disposition" value="inline; filename=CS_#Dateformat(NOW(),'MMDDYYYY')#.xls">
<cfcontent type="application/vnd.ms-excel" variable="#SpreadsheetReadBinary( objSpreadsheet )#">
<cfcatch type = "any">
#rowList#
<cfabort>
</cfcatch>
</cftry>
I have tried adding:
'#DecimalFormat(totalChecklistsByLocPct)# %'"
which then excel doesnt know the correct format.
Then I tried:
<cfset spreadsheetFormatCell( objSpreadsheet, {dataformat: "0.00%"}, 2 )>
Which then just through an error:
Parameter validation error for the SPREADSHEETFORMATCELL function.
Any help on how to add this % sign to the 5 column (not the header or blank cells once the query stops) would be greatly appreciated.
EDIT
Also tried:
<cfset rowList = "'#(rnA eq 1)?assoc_name:''#','#(rnl eq 1)?trans_location:''#','#checklistsByAssocLoc#','#assocChecklistsByLoc#','#NumberFormat(totalChecklistsByAssocLocPct, '0.00')# %'">
Excel still through the error saying its formatted as text.
