It would take data from an ex variable:

let texto = "Exemplo de Texto"

and create a button that takes this variable and generates a download option, in txt format.

You can use the class Blob:

function DownloadArquivo() {
  var data = new Blob(["Exemplo de Texto"]);

  var downloadLink = document.getElementById("aDownloadTxt");
  if (downloadLink == null) {
    downloadLink = document.createElement('a');
    downloadLink.setAttribute('download', 'arquivo.txt');
    downloadLink.setAttribute('id', 'aDownloadTxt');
    document.body.appendChild(downloadLink);
  }

  downloadLink.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(data));
  downloadLink.href = URL.createObjectURL(data);

  downloadLink.style.display = 'none';
  downloadLink.click();
}
<html>

<head>
  <link rel="stylesheet" href="style.css">
</head>

<body>
  <button onclick="DownloadArquivo()">Download</button>
</body>

</html>

    Enzo, when the operation of the code is limited by the security restrictions of the snippet it is best to leave it as non-executable and provide a link to a sandbox where it can be executed, informing of the limitations here of the page.
