LENB
The LENB function returns the number of bytes used to represent a text string. It is useful for languages that use double-byte characters, like Chinese, Japanese, or Korean.

Example explanation
Cell B2, B3 and B4 use the LENB function to calculate the byte length of the text in column A, showing how many bytes the string occupies in memory.
Syntax π
=LENB(text
)
text | The text string for which you want to calculate the number of bytes used for representation. |
About LENB π
Use the LENB function in Excel to find out the number of bytes in a text string. This is particularly useful for languages where characters use multiple bytes, like Chinese, Japanese, or Korean. It helps you understand how many bytes are needed for encoding specific text.
Examples π
To find the number of bytes used by the text string 'δ½ ε₯½δΈη' in a cell, use the LENB function like this: =LENB(A1)
For text in cell A1 like 'γγγ«γ‘γ―', which uses two bytes per character, calculate the total bytes with: =LENB(A1)
Notes π
When using the LENB function, account for language characters in your text string. Excel will provide the byte count needed for multi-byte characters, assisting in data manipulation and formatting.
Questions π
The LENB function plays a crucial role in accurately calculating the byte count for text strings that utilize double-byte characters, particularly when working with languages like Chinese, Japanese, or Korean. It ensures proper handling of multi-byte characters in your spreadsheets and data analysis tasks.
Can the LENB function determine the number of bytes for all text strings?No, the LENB function specifically caters to text strings containing multi-byte characters. It is designed to handle scenarios where characters require more than a single byte for encoding, ensuring correct byte counting for such cases.
Is the output of the LENB function affected by the language settings in Excel?No, the output of the LENB function remains consistent regardless of the language settings in Excel. It solely focuses on computing the number of bytes used to represent a text string, independent of the language or encoding settings in the spreadsheet application.
