LENB function

The LENB function in Jspreadsheet Formulas Pro is a tool that gives you the total number of bytes in a specific text string. It's useful when you're dealing with data that needs byte-level analysis. For instance, if you input LENB("Hello") into a cell, you'll get the result 5, as 'Hello' consists of 5 bytes. This function can be particularly useful when you're dealing with large amounts of text and need a quick way to analyze the data size.

Documentation

Returns the number of bytes in a text string.

Syntax

LENB(text)

Parameter	Description
`text`	The text string whose byte length you want to find.

Behavior

The LENB function is used to return the length of a text string as the number of bytes. This function can be extremely useful when dealing with texts in different languages where a single character may take more than one byte. Here are some common behaviors:

Empty Cells: If the LENB function is used on an empty cell, it will return 0.
Text: If used on a cell containing text, it returns the number of bytes used to represent the characters.
Numbers: If used on a cell containing a number, it will consider the number as a text string and return the number of bytes used to represent it.
Booleans: If used on a cell containing a boolean value, it will consider the boolean as a text string and return the number of bytes used to represent it.
Errors: If used on a cell containing an error, it will return that error.
Arrays: LENB does not operate on arrays.

Common Errors

Error	Description
#VALUE!	This error occurs when the argument is an unsupported type such as an array or a range of cells.
#REF!	This error occurs when the cell reference is not valid.

Best practices

Be aware that LENB counts bytes, not characters. This can lead to different results for languages where a single character may be represented by more than one byte.

Always check for leading or trailing spaces in your text strings that might be affecting the LENB result.

Use the TRIM function in combination with LENB to remove unnecessary spaces.

Be mindful of non-printable characters which might be included in your text string and affect the byte count.

Usage

A few examples using the LENB function.

LENB('apple') returns 5  
LENB('banana') returns 6  
LENB('cherry') returns 6 
LENB("ありがとう") returns 15
