Hi @Kritikz 
use below java script to convert String into Hexadecimal format

function stringToHex(str) {

    let hexString = '';

    for (let i = 0; i < str.length; i++) {

        hexString += str.charCodeAt(i).toString(16);

    }

    return hexString.toUpperCase();

Hi @Kritikz,

To convert a string to hexadecimal on the server side, you need to develop an extension. 

// C# Server-Side Hexadecimal Conversion 

public string ConvertToHex(string input) {    

string hex = "";    

foreach (char c in input) {        

hex += ((int)c).ToString("X2");    

}    

return hex; 

} 

Thanks,
