SGVsbG8gV29ybGQh atob() takes a string and decodes it from Base64. Let's take the encoded string from earlier, 'SGVsbG8gV29ybGQh', and decode it from Base64.In your browser's web developer console, define the string, decode it, and display the decoded string Converts a string to an HTML-encoded string. public static string HtmlEncode (string s ) HTML encoding converts characters that are not allowed in HTML into character-entity equivalents; HTML decoding reverses the encoding.

Prior to decoding, all non-encoded whitespaces are stripped from the input to safeguard the input's integrity. This option is useful if you intend to decode multiple independent data entries that are separated by line breaks
