I would start by explaining briefly the skills for the great job: Copy Typing-- copy and paste or typing an already hand written document into the computer system.
Data Entry-- entering data into a computer program.
Data Processing-- copy, paste, save, edit name and rename, create and save, move to directories.
Excel-- a special sheet work that involves professional accounting calculations where you fills in data into its rows and columns.
Copy and pasting involves using the internet say "Google search" copying an article from a page in the internet and pasting in Microsoft office word, which will involve editing the text, adding other articles related with my work. Secondly, copy typing could be a scanned hand written note\text on a paper send to me through the internet so that I can type and format it into a Microsoft office word, excel, power point or whatever file format that may be specified that I work on. Data entry is in an already formatted program or file in which I have to key in data of whatever the program so desires, so it is important to know the kind of package or program you are working on in order to understand what kind of data to enter into the document on the program. Data processing involves; copying, pasting, saving, naming files, documents and folders in different directories. I do use excel to format calculations in program\documents such as proforma invoice, receipt, bills\ quotation etc. Considering all above, I am the best candidate for this job.
