LEN function returns the number of characters in a text string.
LENB function returns the number of bytes used to represent the characters in a text string.
What is the difference between LEN and LENB?
LEN is intended for use with languages that use the single-byte character set (SBCS), whereas LENB is intended for use with languages that use the double-byte character set (DBCS). The default language setting on your computer affects the return value in the following way:
- LEN always counts each character, whether single-byte or double-byte, as 1, no matter what the default language setting is.
- LENB counts each double-byte character as 2 when you have enabled the editing of a language that supports DBCS and then set it as the default language. Otherwise, LENB counts each character as 1.
The languages that support DBCS include Chinese (Simplified), Chinese (Traditional), Korean, and Japanese.
Text Required. The text whose length you want to find. Spaces count as characters.
Example 1: LEN
The example may be easier to understand if you copy A1:C4 to a blank worksheet.
Example 2: LENB
equals 8. LENB returns 8, because each character is counted as 2.
equals 4. LEN returns 4, because each character is counted as 1. LEN returns 4 no matter what the default language setting is on your computer.
