Just a quick one. I wrote this generic function today to convert any query to a valid JSON string with lowercase element names.

<cffunction name="queryToJSON" returntype="string" access="public" output="yes">
<cfargument name="q" type="query" required="yes" />
<cfset var o=ArrayNew(1)>
<cfset var i=0>
<cfset var r=0>
<cfloop query="Arguments.q">
<cfset r=Currentrow>
<cfloop index="i" list="#LCase(Arguments.q.columnList)#">
<cfset o[r][i]=Evaluate(i)>
</cfloop>    
</cfloop>
<cfreturn SerializeJSON(o)>
</cffunction>

Just call this function with:

<cfset myJSON=queryToJSON(yourQueryName)>
