I'm very skilled in processing Excel, Word, especially Data Entry and Data Processing by VBA application. For example, (when I learned VB by myself for some time,) I set a question to myself which's "apply VBA to array by random 256 pieces of number [17012650001-17012650256] into range [A2:A257]". Depending on my knowledge of VBA, I designed a small "macro sub" to process data accorded with expectations (and past the examination).
