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.
A spreadsheet entry job requires the worker to enter data into a spreadsheet, which is easier than using database software. Often times, the employer requires you to research information, or type data from other documents and input the data into a spreadsheet as specified by the employer.
