Data entry clerks help companies process information by inputting, maintaining and retrieving data using computer systems and ensuring that information is collated and stored in an accurate and efficient manner. Data entry clerks update, maintain and retrieve information which is held on a company’s computerised information storage and retrieval systems. They also transfer data held on manual records to computer files and ensure that important data is collated, processed and stored appropriately. Data entry clerks are responsible for transferring both words and numerical data into spreadsheets or databases. They use basic word processing and database packages but may also work with tailor-made software packages to meet the specific data needs of individual companies.
