In addition to direct cost savings, using automation realizes a number of other benefits for companies. As people perform the same tasks repeatedly, they tend to pay less attention each time, which inevitably results in mistakes being made. However, when the task is performed by the computer, the result is equally accurate no matter how many times it is performed. Computers will never become bored with a task and give it less attention. As a result, there is a significantly reduced risk of human error.
The predictability that a macro brings to the result also facilitates the organization of files, because each file has been modified in the same manner. In the case of spreadsheet data formatting, for example, this means the resulting data is ready to be processed without concern regarding consistency. A zero in the data will never be read as the letter o, and every cell will have the same text layout. This predictability also has the added benefit of producing data that is accessible to additional macros, since macros and scripts not only produce predictable outputs, but require predictable inputs. . .
