Replace

Description

Replaces occurrences of substring1 in a string with substring2, in a specified scope. The search is case sensitive.

Returns

The string, after making replacements.

Function syntax

Replace(string, substring1, substring2 [, scope ])

Parameters

Parameter	Description
`string`	A string or a variable that contains one. String in which to search.
`substring1`	A string or a variable that contains one. String for which to search
`substring2`	String that replaces `substring1`
`scope`	one: replaces the first occurrence (default) all: replaces all occurrences

Usage

To remove a string, specify the empty string ("") as substring2.

You do not need to escape comma characters in strings. For example, the following code deletes the commas from the sentence:

replace("The quick brown fox jumped over the lazy cow, dog, and cat.",",","","All")
