How do I use the MID function in Excel?

The MID function is a built-in function in Microsoft Excel that allows you to extract a substring from a string of text, based on a specified starting position and length. The syntax for the MID function is as follows:

MID(text, start_num, num_chars)

The 'text' argument is the string of text from which you want to extract a substring. The 'start_num' argument is the starting position of the substring you want to extract. The 'num_chars' argument is the number of characters you want to extract.

For example, if you have a cell containing the text 'Hello World', and you want to extract the word 'World', which starts at the 7th character and is 5 characters long, you could use the following formula:

=MID(A1, 7, 5)

This would return the value 'World'.

It's important to note that the MID function is case-sensitive, so 'W' is not the same as 'w'. Also, if you attempt to extract more characters than are available in the string, the function will return an error.
