MIDB function

The MIDB function in Jspreadsheet Formulas Pro is a useful tool for extracting a specific part of a text string. You simply specify the starting position in the text from where you want to begin extracting, and then state the exact number of bytes you wish to extract. This is particularly helpful when you need to analyze or manipulate certain sections of a text string within your spreadsheet. It's a straightforward, powerful feature that enhances your data processing capabilities in Jspreadsheet.

Documentation

Returns a specific number of bytes from a text string starting at the position you specify.

Syntax

MIDB(text, start_num, num_bytes)

Parameter	Description
`text`	The text string that contains the characters you want to extract.
`start_num`	Specifies the position (in bytes) of the first character you want to extract. The first byte in the text is 1.
`num_bytes`	Specifies the number of bytes you want MIDB to return.

Behavior

The MIDB function is used to extract a specific number of characters from a text string, starting at a specific position and counting each byte used by the characters. This function may not work as expected if non-English characters are used, as such characters often use more than one byte.

If the start_position argument is less than 1, the MIDB function will return an error.
If the num_bytes argument is less than 0, the MIDB function will return an error.
If the num_bytes argument is greater than the length of the text string, the MIDB function will return all characters in the string from the start_position to the end of the string.
If a referenced cell is empty, the MIDB function will return an empty string.
If a boolean value is used, the function will treat TRUE as text and FALSE as an empty string.
If an error value is used, the MIDB function will return that error.

Common Errors

Error	Description
#VALUE!	This error is displayed when the start_position argument is less than 1.
#VALUE!	This error is displayed when the num_bytes argument is less than 0.
#VALUE!	This error is displayed if either of the provided arguments are non-numeric.

Best practices

Generally, it is best to use the MIDB function with text strings and avoid using it with boolean values or error values.

Be cautious when using non-English characters, as they may use more than one byte and this can affect the output of the MIDB function.

Always make sure that the start_position and num_bytes arguments are positive numbers to avoid errors.

Use the LENB function to count the number of bytes in a text string before using the MIDB function. This can help you determine the correct arguments to use.

Usage

A few examples using the MIDB function.

MIDB('apple', 1, 3) returns 'app'  
MIDB('banana', 3, 2) returns 'na'  
MIDB('cherry', 2, 4) returns 'herr'  
MIDB("ありがとう", 1, 6) returns "あり"
