LEN, LENB functions

This article describes the formula syntax and usage of the LEN and LENB functions in Microsoft Excel.

Description

LEN returns the number of characters in a text string.

LENB returns the number of bytes used to represent the characters in a text string.

Important   LENB counts 2 bytes per character only when a DBCS language is set as the default language. Otherwise LENB behaves the same as LEN, counting 1 byte per character.

The languages that support DBCS include Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.
