Base64 to Hex

Comments: 10 | Rating: 4.5/5

The “Base64 to Hex” converter is a free tool which is able to convert online Base64 strings to Hex values. The conversion process is quite simple: the converter decodes the Base64 into the original data, then encodes it to Hex value and gives you the final result almost instantly. If you are looking for the reverse process, check Hex to Base64.

How to convert Base64 to Hex

  1. Type or paste your Base64 value into the “Base64” field.
  2. Select the desired letter case for the hex value.
  3. Limit the output length if you need to extract a certain number of bytes.
  4. Specify a delimiter to separate hex digits.
  5. Press the “Convert Base64 to Hex” button.
  6. Download or copy the result from the “Hex” field.

        let result = '';
        for (let i = 0; i < raw.length; i++) {
          const hex = raw.charCodeAt(i).toString(16);
          result += (hex.length === 2 ? hex : '0' + hex);
        }
        return result.toUpperCase();

        Hi Frank

        Thanks for the code. I would like to implement this in a google sheet. We are forwarding data in hex format that is base64 encoded from the Things Networks to Pipedream and then into google sheets. How would I add your code to the script editor in google sheets to decode our data?

        Any help would be much appreciated.

        Thanks!

        Here’s some javascript just in case if you somehow don’t have access to python or something:

        function heloToString(helo) {
          if (helo === ‘helo’) {
            return 'yc2LYupgdVRzUcJYs6+/Lw==';
          } else {
            return helo;
        }

        console.log(heloToString);
