    Function name:





    Determines the number of bytes in a supplied text string, including those occupied by space characters.




    Returns a non-negative integer that is the number of bytes occupied by the supplied string.


    Text is a text string (in quotation marks), a number, or a reference to a cell containing one of those types, whose length in bytes is to be determined.

    General information about byte-position functions

    Note pin.svg

    For convenience, the information in this subsection is repeated on all pages describing Calc’s byte-position functions.

    Calc provides several byte-position text functions, which are intended to be used with double-byte character set (DBCS) languages. These functions are FINDB, LEFTB, LENB,MIDB, REPLACEB, RIGHTB, and SEARCHB. Each has an equivalent "ordinary" text function with a similar name but without the final letter "B".

    Calc considers double-byte characters to be those characters lying within the following Unicode code blocks:

    • Bopomofo Extended (U+31A0 ... U+31BF)
    • Bopomofo (U+3100 ... U+312F)
    • CJK Compatibility Forms (U+FE30 ... U+FE4F)
    • CJK Compatibility Ideographs Supplement (U+2F800 ... U+2FA1F)
    • CJK Compatibility Ideographs (U+F900 ... U+FAFF)
    • CJK Compatibility (U+3300 ... U+33FF)
    • CJK Radicals Supplement (U+2E80 ... U+2EFF)
    • CJK Strokes (U+31C0 ... U+31EF)
    • CJK Symbols and Punctuation (U+3000 ... U+303F)
    • CJK Unified Ideographs Extension A (U+3400 ... U+4DBF)
    • CJK Unified Ideographs Extension B (U+20000 ... U+2A6DF)
    • CJK Unified Ideographs (U+4E00 ... U+9FFF)
    • Enclosed CJK Letters and Months (U+3200 ... U+32FF)
    • Halfwidth and Fullwidth Forms (U+FF00 ... U+FFEF)
    • Hangul Compatibility Jamo (U+3130 ... U+318F)
    • Hangul Jamo (U+1100 ... U+11FF)
    • Hangul Syllables (U+AC00 ... U+D7AF)
    • High Private Use Surrogates (U+DB80 ... U+DBFF)
    • High Surrogates (U+D800 ... U+DB7F)
    • Hiragana (U+3040 ... U+309F)
    • Ideographic Description Characters (U+2FF0 ... U+2FFF)
    • Kanbun (U+3190 ... U+319F)
    • Kangxi Radicals (U+2F00 ... U+2FDF)
    • Katakana (U+30A0 ... U+30FF)
    • Low Surrogates (U+DC00 ... U+DFFF)
    • Private Use Area (U+E000 ... U+F8FF)
    • Yi Radicals (U+A490 ... U+A4CF)
    • Yi Syllables (U+A000 ... U+A48F)

    See Wikipedia's Unicode block page for more information about these blocks.

    In addition, code points U+005C and U+20AC are taken to be double-byte characters if the system language is set to Japanese.

    As noted in ODF 1.2, byte positions are implementation-dependent and so reliance upon them reduces interoperability.


    Formula Description Returns
    =LENB("Good afternoon") Here the supplied string comprises 14 single-byte characters and so the function returns 14. 14
    =LENB("Good afternoon") Here the supplied string comprises 14 double-byte characters and so the function returns 28. 28
    =LENB(D1) where cell D1 contains the number 12345.67. Here the function returns 8. 8
    =LENB("12,345.67") Here the function returns 9. Note that in this case the number is passed as a string - LEN reports an error if the quotation marks are omitted because the number includes a comma digit group separator. 9
    =LENB("") Here the function returns 0, since the argument is the empty string. 0
