As a spreadsheet entry worker, you must have good computer skills, especially with using spreadsheets. It is also important that you have a good typing speed, including attention to detail.

Many companies that collect data hire spreadsheet operators. These include research organizations, shopping malls that have collected data from customers, hospitals, learning institutions and recruitment agencies that hire on their behalf.
