You'll have to change %0D%0A to

using JavaScript.

Thanks! I see a lot of your answers on here.
I am still getting something wrong (I dont know javascript). Can I ask you for one more answer? I'm not proficient in js so I am really not sure why the following code is not working. Any ideas?
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/
var add_newline = "${e://Field/links}";
add_newline.val(add_newline.val().replace(/%0D%0A/gi, "
"));
My embedded data field looks like this:
links=SAMPLE_LINK1%0D%0ASAMPLE_LINK2

My guess is that I am not sending the substituted value back to my survey anywhere so I am not really setting it to be printed, right?

Your guess is correct. add_newline is a variable. .val() is only for input elements. You could do this:
Qualtrics.SurveyEngine.addOnload(function() {
var links = "${e://Field/links}";
Qualtrics.SurveyEngine.setEmbeddedData("links",links.replace(/%0D%0A/gi,"
"));
});

Sorry TomG
I tried adding the snippet on your response to a previous question, then a page break, and then pipe my text since I know you said before you should not set embedded data values on the same question where you pipe them to:
https://www.qualtrics.com/community/discussion/5171/setembeddeddata-not-writing-back-to-qualtrics
However the piped text

${e://Field/links}

still shows no changes after the replacement.
I also tried setting the value directly to the survey flow on an embedded data block but it didn't work:
I tried:
links2 = $e{ e://Field/links links.replace(/%0D%0A/gi,"
")}
And also a test:
links2 = Qualtrics.SurveyEngine.setEmbeddedData("links2", "Test");

and changed my piped text to

${e://Field/links2}

But had no results with either method.

Update:
Passing newline characters to a piped text in Qualtrics works using Q_EED, but you need two things:
You must use the

1. tag as TomG indicated (but no need of JS magic if you use Q_EED - I could never get it working with JS).

You must add a space between the beginning and the end of the tag `

1. ` for it to work correctly.

If you need more help refer to the documentation here:

If you need some help with base64 encoding, you can use my Python script below:

class converter():

  def mssg(self):
    print(self.lstr)


  def decode (self,normal_str):
    secret = base64.b64decode(normal_str)
    print(secret.decode("utf-8"))


  def encode (self,encoded_str):
    bys = bytes(encoded_str, 'utf-8')
    secret = base64.b64encode(bys)
