LENB function
Returns the number of bytes used to represent the characters in a text string
Legacy DBCS byte-oriented len function. Microsoft deprecates LENB; prefer LEN for new workbooks. This local model counts Latin-1 and half-width kana as one byte and other code points as two; an incomplete double-byte character in a slice becomes a space. It is not a UTF-8 storage measure. Native Excel byte behavior depends on language and workbook settings, and full native locale compatibility remains unverified.
Syntax
LENB(text)Square brackets indicate optional arguments.
Arguments
| Argument | Required | Meaning |
|---|---|---|
| text | Yes | The text whose length you want to find. Spaces count as characters."Univer" |
Try LENB
Count a mixed label in legacy DBCS bytes
=LENB(A2)The byte count is 1+2+1+2+1=7; the character count from LEN is 5. This example uses a legacy double-byte character set (DBCS): A, B and C use one byte each; 漢 and 字 use two each. Byte positions are A=1, 漢=2–3, B=4, 字=5–6 and C=7. These positions differ from UTF-8 storage sizes. Microsoft deprecates the B-suffixed function; prefer the corresponding character function for new workbooks. Native byte counting depends on language settings.
