ENCODEURL Function Syntax



text A string you want to encode.

ENCODEURL Function Example

A URL (Uniform Resource Locator) is the address of a resource on the world wide web (www). These addresses are formed based on a set of syntax rules. While some characters, including digits(0-9), letters(A-Z, a-z), and some special characters  (-, ., _, ~), can be used without issues, some characters are listed to be unsafe (space, \, <, >, {, }), and some others are reserved for different segments of a URL (?, /, #, :).

Encoding helps convert these "disallowed" characters into percent-codes. This way, you can use any character you want.

Using the ENCODEURL function is easy - You only need to provide a string that you want to encode.
