Convert byte array into file

Connect and share knowledge within a single location that is structured and easy to search. I try to convert a file that i get through an input file into a byte[].

I tried with a FileReader, but i must miss something :. Faced a similar problem and its true the 'reader. So I have cast it to Uint8Array object. This too is not a perfect 'byte[]' ,so I had to create a 'byte[]' from it.

Here is my solution to this problem and it worked well for me. Saw the comments and seems you did the same, still wanted to share the approach. Seems to me you just want to get files into an array? How about these functions - one where you can read it as text, another as a base64 byte string, and if you really want the readAsArrayBuffer array buffer output, I've included that, too:.

Here is a modified, and in my opinion easier version of the accepted answer. This function returns a Promise with a value of the byte[].
