An escape/unescape string online tool is a tool that helps you convert a string of text into a format that can be safely used in a web application. The tool takes your string and escapes any special characters, such as quotation marks, so that they can be safely used in your code. It also unescapes any escaped characters so that you can see the original string.
Escape string is a sequence of characters that allows you to control the generation of a target string, usually for use in programming or web development. The most common use of escape string is to add special characters to a target string that would otherwise be interpreted as part of the target string. For example, an escape string can be used to add quotation marks to a target string so that the quotation marks are not interpreted as part of the target string.
The escape sequence is a series of characters that represents a particular character or action. When an escape sequence is encountered by the computer, it is interpreted as a command to perform a certain action. Common escape sequences include "\\" which represents a Backslash character, and "\t" which represents a tab character.
