Hey, I have a great experience in MS- excel and I like to do work in MS- Excel. To convert 500 ms excel file in just 1 file, it is difficult but I like that works which is difficult and I am that much daring to do that work because I love to do this type of job. I will do your work with full accuracy within few days. I have a good experience in MS-office.
Thanks
Regards
Adarsh
