Dear Concern,
I am interested in your job post involving these skills. It says that you are looking for someone who knows English & MS Office, also who is a detail-oriented person. I think that I am the right person for the job. I have very good experience in Data Entry, Data Processing and making spreadsheet.
As a data entry operator, I also am detail-oriented. Rest assured all the data will be accurately entered, no more, no less.
I am looking forward to discussing with you about this job post.
