REPLACE, REPLACEB functions

This article describes the formula syntax and usage of the REPLACE and REPLACEB  function in Microsoft Excel.

Description

REPLACE replaces part of a text string, based on the number of characters you specify, with a different text string.

REPLACEB replaces part of a text string, based on the number of bytes you specify, with a different text string.

Important   REPLACE is intended for use with languages that use the single-byte character set (SBCS), whereas REPLACEB is intended for use with languages that use the double-byte character set (DBCS). The default language setting on your computer affects the return value in the following way:

  • REPLACE always counts each character, whether single-byte or double-byte, as 1, no matter what the default language setting is.

  • REPLACEB counts each double-byte character as 2 when you have enabled the editing of a language that supports DBCS and then set it as the default language. Otherwise, REPLACEB counts each character as 1.

The languages that support DBCS include Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.

Syntax

REPLACE(old_text, start_num, num_chars, new_text)

REPLACEB(old_text, start_num, num_bytes, new_text)

The REPLACE and REPLACEB function syntax has the following arguments:

  • Old_text    Required. Text in which you want to replace some characters.

  • Start_num    Required. The position of the character in old_text that you want to replace with new_text.

  • Num_chars    Required. The number of characters in old_text that you want REPLACE to replace with new_text.

  • Num_bytes    Required. The number of bytes in old_text that you want REPLACEB to replace with new_text.

  • New_text    Required. The text that will replace characters in old_text.
