Blob to String conversion example in JavaScript using the FileReader API. This displays "Lorem ipsum sit" in the console.
const blb = new Blob(["Lorem ipsum sit"], {type: "text/plain"});
const reader = new FileReader();
// This fires after the blob has been read/loaded.
reader.addEventListener('loadend', (e) => {
const text = e.srcElement.result;
console.log(text);
});
// Start reading the blob as text.
reader.readAsText(blb);
