First, the LEN function counts total characters in the cell B5.
Next SUBSTITUTE removes all "line returns" from the text in B5 by looking for CHAR(10) which is the character code for the return character in Windows. LEN returns the result inside of a second LEN, which counts characters without carriage returns.
The second count is subtracted from the first, and 1 is added to the final result, since the number of lines is the number of returns + 1.
Dealing with empty cells
The formula in the example shown will return 1 even if a cell is empty. If you need to guard against this problem, you can wrap the formula in IF statement like so:
Excel doesn't have a dedicated function for counting words in a cell. However, with a little ingenuity, you can create such a formula using the SUBSTITUTE and LEN functions, with help from TRIM, as shown in the example. At a high level, this formula...
At the core, this formula looks for a line delimiter ("delim") and replaces it with a large number of spaces using the SUBSTITUTE and REPT functions. Note: In older versions of Excel on a Mac, use CHAR(13) instead of CHAR(10). The CHAR function...
The Excel SUBSTITUTE function replaces text in a given string by matching. For example =SUBSTITUTE("952-455-7865","-","") returns "9524557865"; the dash is stripped. SUBSTITUTE is case-sensitive and does not support wildcards.
The Excel CHAR function returns a character when given a valid character code. CHAR can be used to specify characters that are hard to enter in a formula. For example, CHAR(10) returns a line break, and can be used to add a line break to text in...
