Decode URLs in Google Sheets creating a custom fucntion in Apps Script

decode URL Apps Script

/* Both these funcitons will work fine */

// As a function declaration
function DECODE(url) {
  return decodeURI(url)
}

// Or as an arrow function
const DECODEURL = (url) => decodeURI(url)

This worked best for me thanks @jlhernando

/* Both these funcitons will work fine */

// As a function declaration
function DECODE(url) {
return decodeURIComponent(url)
}

// Or as an arrow function
const DECODEURL = (url) => decodeURIComponent(url)

Just to make the above clear, the function needs to use decodeURIComponent (not decodeURI), so the code should be...

// As a function declaration
function DECODE(url) {
    return decodeURIComponent(url)
}

// Or as an arrow function
const DECODEURL = (url) => decodeURIComponent(url)

Thanks @jlhernando for sharing this originally, and @campiotto for your correction 👍🏼
