How to generate an LEFTB FUNCTION formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “To get the LEFTB formula, you can ask the AI chatbot the following question: "What formula can I use in Excel to extract a specified number of bytes from the beginning of a text string, considering that the LEFT function may not work due to multi-byte character encoding?"

LEFTB FUNCTION formula syntax

The LEFTB function in Excel is used to extract a specified number of characters from the beginning of a text string, where each character is represented by two bytes (such as double-byte character set languages like Chinese or Japanese). The syntax for the LEFTB function is: LEFTB(text, num_chars) - text: This is the text string from which you want to extract characters. - num_chars: This is the number of characters you want to extract from the beginning of the text string. Note that the LEFTB function is designed specifically for double-byte character set languages, so it counts the number of bytes instead of characters. If you are working with single-byte character set languages, you can use the LEFT function instead.

Use Cases & Examples

In these use cases, we use the LEFTB function to extract a specified number of characters from the beginning of a text string, considering that each character may be represented by multiple bytes in a double-byte character set (DBCS) language.
