When using the MID function, which parameters are needed to specify which text to extract?

The MID function in spreadsheet software, such as Excel, is used to extract a specific substring from a text string. To effectively use the MID function, you need to specify three key parameters: the original text (string), the starting position from which to begin the extraction, and the number of characters to extract.

In this instance, the correct choice identifies the parameters as "start_num" and "num_char." The "start_num" parameter indicates the position in the text string where the extraction should begin. It's important to note that this position is counted from the left, starting at 1. The "num_char" parameter specifies how many characters to extract from the starting point. Therefore, with these two parameters, you can effectively control both the starting point and the length of the substring you intend to retrieve.

This understanding is crucial in data manipulation and analysis, as extracting specific pieces of text is often needed for organizing or analyzing datasets.
