Is there a way to check whether an Excel file has a header or not?

Question

Hi!
I'm currently using POI Utility to read and write Excel files.
You normally use the HasHeaderRow = true / false to specify whether the file has a header or not.
Now, let's say I have a program that needs to read Excel files from a directory, some have headers, some don't.
Is there a way to know dynamically whether a header has been defined or not?
Then, for those having headers, the flag will be set as true, while for those which don't have any header, the flag will be set as false.
E.g.
<!--- Create an instance of the POIUtility.cfc. --->
    <cfset objPOI = CreateObject(
        "component",
        "POIUtility"
        ).Init()
        />
<!--- Set directory --->
<cfset currentDirectory = GetDirectoryFromPath(GetTemplatePath()) & "newDir">
<!--- Check whether the directory exists. --->
<cfif DirectoryExists(variables.currentDirectory)>
     <!--- Read files from the specified directory --->
     <cfdirectory action="list" directory="#variables.currentDirectory#" type="file" filter="*.xls" name="qDirectory">
     <!--- Check if the directory has any Excel file --->
     <cfif variables.qDirectory.recordcount gt 0>
          <!--- Loop query --->
     <cfloop query="variables.qDirectory">
               <!--- Check if header is present in each of the file --->
                    IF headerExists THEN
                         headerFlag = true
                    ELSE
                         headerFlag = false
                    END IF
               <!--- Read Excel File --->
            <cfset objSheet = objPOI.ReadExcel(FilePath = #variables.qDirectory.name#, HasHeaderRow = #variables.headerFlag#, SheetIndex = 0) />
          </cfloop>
     </cfif>
</cfif>
Any help would be most welcome.
Thanks and regards,

Hi cfSearching,
Many thanks for your reply! I really do appreciate!
However, I've still got 1 more question for you.
At the moment, I'm using POI and sometimes cfx_Excel2Query to read Excel files.
In both cases, you have to specify whether the first row is a header.
How would you read the Excel file to check whether the 1st row is the header?
I've tried using cffile, but I get all sorts of "garbage"
        <cffile action="read" file="#variables.filename#" variable="xlsResult">
        <cfloop index="i" list="#variables.xlsResult#" delimiters="#chr(13)#&#chr(10)#">
            <cfif variables.i eq 1>
                <cfoutput>
                    Test 1st Row: #trim(replacenocase(listgetat(variables.i,1,","),'"',"","All"))#
                </cfoutput>
            </cfif>
        </cfloop>
I get the following output:
ÐÏ à¡± á����.... etc etc
I'd be very much grateful if you could please advise on the latter at your earliest convenience.
Thanks and best regards,
