I speak perfect English so you won't have to deal with any broken English while talking to me.
I have past experience using Excel and dealing with huge amounts of data in an engineering setting, so managing your data will be no problem.
I work with Macros and I can provide the Macro to you with documentation, so you won't need another freelancer next time, you can just use the macro.
If you wish I can provide you with a demosntration of my skills FREE OF CHARGE.
