problem writing excel sheet using python

[vineeth menneni]

The belwo is the code, I have also tried writing it row by row with xlsxwrites passing argument constant_memory:True. I donot know if my looping code is ineffective.       

for req_param in request.GET.get("Req-Tables").split(","):
        sheet_names.append(req_param)
        title.append(req_param)
        report_data=db_exec_query( param_table_map[req_param])
        sheet_names[key]=wb.active        
        if key!=0:
            sheet_names[key]=wb.create_sheet(title= (title[key][:15] ) if title[key] > 15 else title[key])
 req_param, sys.getsizeof(report_data))
        count= 0
        for r in report_data:
            try:
                sheet_names[key].append(r)
            except:
                sheet_names[key].append(str(c).decode('cp1252') for c in r)
        key=key+1
    
    wb.save(response)

The problem is that i am loading a table data from MYSQL db which has 600k rows and 15 columns (approximately 100mb data). The error that the terminal shows is that "MemoryError". I just wanted to know if it is possible to create a excel sheet with the above said data in less than one minute using any packages in python.
