RIGHTB
The RIGHTB function returns a specified number of bytes from the end of a text string. This function is particularly useful when working with multibyte character sets where characters may occupy multiple bytes, such as in languages like Chinese, Japanese, or Korean.
Syntax
=RIGHTB(text, num_bytes) Arguments
| Argument | Required | Description |
|---|---|---|
| text | Yes | The text string from which you want to extract bytes. |
| num_bytes | Yes | The number of bytes to extract from the end of the text string. |
About
When dealing with multibyte character sets in Excel, the RIGHTB function proves to be a valuable ally. It allows users to extract a specified number of bytes from the end of a text string, catering to scenarios where characters may occupy multiple bytes due to language-specific encoding requirements. This function ensures precision in handling text manipulation tasks involving languages like Chinese, Japanese, Korean, and others with complex character structures that extend beyond the standard single-byte encodings common in Western languages.
Examples
Let's say you have a text string in Chinese characters '你好世界' (meaning 'Hello, World') and you want to extract the last 6 bytes. The RIGHTB formula would be: =RIGHTB('你好世界', 6)
Suppose you have a text string containing Korean characters '안녕하세요' (meaning 'Hello') and you wish to retrieve the last 4 bytes. The RIGHTB formula would be: =RIGHTB('안녕하세요', 4)
Suppose you have a text string containing Korean characters '안녕하세요' (meaning 'Hello') and you wish to retrieve the last 4 bytes. The RIGHTB formula would be: =RIGHTB('안녕하세요', 4)
Tips & notes
Ensure you are working with text strings that contain multibyte characters when employing the RIGHTB function, as it is specifically designed for handling byte extraction from such character sets. Be mindful of the byte length of characters in the language being used to accurately determine the number of bytes to extract from the end of the text string.
Common questions
How does the RIGHTB function handle multibyte characters?
The RIGHTB function is adept at capturing a specified number of bytes from the end of a text string, making it an ideal choice for dealing with multibyte characters prevalent in languages with complex character encoding requirements.
Can I extract a fixed number of characters rather than bytes using the RIGHTB function?
If you are working with single-byte character sets or desire to extract a fixed number of characters from the end of a text string, you can choose to use the RIGHT function in Excel, which operates based on character count rather than bytes.
