This chapter shows how to count the number of words in a cell.
1a. The TRIM function returns a string with leading spaces, extra spaces and trailing spaces removed.
1b. To get the length of the string with normal spaces, we combine the LEN and TRIM function.
2a. The SUBSTITUTE function replaces existing text with new text in a text string. We use the SUBSTITUTE function to get the string without spaces.
2b. To get the length of the string without spaces, we combine the LEN and SUBSTITUTE function.
3. Now comes the simple trick. To get the number of words, we subtract the length of the string without spaces (10) from the length of the string with normal spaces (12) and add 1.
