REPLACEB function

The REPLACEB function in Jspreadsheet Formulas Pro is a useful tool that allows you to substitute a specific sequence of bytes in a text string with a new set of bytes. This means you can change certain parts of your text without having to manually edit it. You just need to specify the original text, the starting position of the sequence you want to change, the length of this sequence, and the new bytes you want to replace it with. It is an efficient method for modifying text data in your spreadsheets.

Documentation

Replaces a sequence of bytes in a string with another set of bytes.

Syntax

REPLACEB(old_text, start_num, num_bytes, new_text)

Parameter	Description
`old_text`	The text string that contains the bytes you want to replace.
`start_num`	The position of the first byte you want to replace in old_text.
`num_bytes`	The number of bytes you want to replace in old_text.
`new_text`	The replacement set of bytes.

Behavior

The REPLACEB function is used to replace part of a text string, based on the number of bytes you specify, with a different text string. It's mostly useful in double-byte character sets where a single character can be represented as either one or two bytes.

REPLACEB does not look for repeated text. It simply replaces text starting at the given byte position for the specified number of bytes.
If the old text is found more than once in the text string, REPLACEB will replace only the first instance of the old text.
If the start_num is greater than the length of the text, REPLACEB will return a #VALUE! error.
If num_bytes is greater than the length of the text (from the start_num), REPLACEB will replace all the text from the start_num.
If the start_num or the num_bytes is non-numeric, REPLACEB will return a #VALUE! error.
REPLACEB can handle empty cells, and will simply return an empty cell.
If boolean values are used, they will be converted into their text equivalents: TRUE to "TRUE" and FALSE to "FALSE".
If an error cell is referenced in the function, REPLACEB will return that error.

Common Errors

Error	Description
#VALUE!	This error occurs if the `start_num` is less than 1 or if the `num_bytes` is less than 0. It will also occur if `start_num` or `num_bytes` is non-numeric.

Best practices

Always ensure that the start_num is greater than or equal to 1 and num_bytes is greater than or equal to 0 to avoid the #VALUE! error.

Use REPLACEB function when working with double-byte languages like Japanese, Chinese, or Korean as it counts each double-byte character as 2 instead of 1.

Be aware that REPLACEB will only replace the first instance of the old text. If you need to replace all instances, consider using a different function or method.

Always check your text for possible errors before applying the REPLACEB function to avoid returning an error result.

Usage

A few examples using the REPLACEB function.

REPLACEB("Hello World", 7, 5, "Universe") → "Hello Universe"
REPLACEB("John Doe", 2, 3, "ane") → "Jane Doe"
REPLACEB("123456789", 3, 3, "ABC") → "12ABC789"
REPLACEB("こんにちは", 1, 2, "##") → "##にちは"
