Hi,

I have base64 data and I would like to convert it to Hex … Is it possible to use Decode Text under Computed - Experimental Column. If so, what do I put into Encoding/Decoding Column. I tried using Hex but it does not work. Appreciate feedback. Thank you.

You can try this in a JavaScript column.

```auto
function base64ToHex(base64) {
  try {
    const raw = atob(base64);
    let hex = '';
    
    for (let i = 0; i < raw.length; i++) {
      const hexChar = raw.charCodeAt(i).toString(16);
      hex += (hexChar.length === 2 ? hexChar : '0' + hexChar);
    }
    
    return hex;
  } catch (err) {
    return '';
  }
}

return base64ToHex(p1)

```

Not sure if your example string is valid base64, but it returned an error for me.

Thanks Thinh … looks correct for me.
