Companies will hire you when they have a lot of information that they need inputted into spreadsheets, and sorted in a particular manner. Many times, this includes information typed on paper and scanned into JPEG, or using online forms. When companies have a lot of data to input into spreadsheets or a database, they will outsource the job, but often times this is a short-lived job. However, you may find recruitment and staffing who will hire you for the long-term; in many cases, when your contract ends, the staffing agency will find you another job quickly.
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.
