Chapter 16: Writing Home about Text Functions
Use LEFT and RIGHT to extract characters from the start or end of a text
string. Use MID to extract characters from the middle.
Staying in the MIDdle
MID is a powerful text extraction function. It lets you pull out a portion of a
larger string — from anywhere within the larger string. The LEFT and RIGHT
functions allow you to extract from the start or end of a string but not the
middle. MID gives you essentially complete flexibility.
MID takes three arguments: the larger string (or a reference to one); the
character position to start at; and how many characters to extract. Here’s how to
use MID:
2. Enter =MID( to start the function.
4. Enter a comma ( ,).
5.Enteranumbertotellthefunctionwhichcharactertostarttheextraction from.
This number can be anything from 1 to the full count of characters of
the string. Typically the starting character position used with MID is
greater than 1. Why? If you need to start at the first position, you may as
well use the simpler LEFT function. If you enter a number for the
starting character position that is greater than the length of the string, then
nothing is returned.
6. Enter a comma ( ,).
If you enter a number that is greater than the remaining length of the
string, then the full remainder of the string is returned. For example, if
you tell MID to extract characters 2 through 8 of a six-character string,
then MID returns characters 2 through 6.
8. Type a ), and press Enter.
Here are some examples of how MID works:
