LEFT, LEFTB functions: Description, Usage, Syntax, Examples and Explanation

What are LEFT, LEFTB functions in Excel?

LEFT, LEFTB functions are TEXT functions in Microsoft Excel.

LEFT returns the first character or characters in a text string, based on the number of characters you specify.

While, LEFTB returns the first character or characters in a text string, based on the number of bytes you specify.

Important:

These functions may not be available in all languages.
LEFTB counts 2 bytes per character only when a DBCS language is set as the default language. Otherwise LEFTB behaves the same as LEFT, counting 1 byte per character.

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