Since that cell basically just contains the contents of a csv file, all you need to do is take the contents of the cell and move them over to an empty file. From top to bottom our Output setting do the following:
2. File Format: obvious
3. Delimeters: "\0" just means don't use delimiters (This is where the magic happens that lets the output not be considered a single block of text because quotes will not be added to the output). This is contrasted against leaving the field blank, which tells the system to use the empty string as the delimiter (i.e. "\0" = DO NOT USE delimiter; [Blank] = USE "" AS delimiter)
4. First Row Contains Field Names: Leave this unchecked because we do not want Alteryx to use the column name "DownloadData" in the output, rather you want to sneakily insert your own column names, which came to you courtesy of the Download Tool output and sits patiently in the single cell with all the other data.
5. Quote Output Fields: I just wanted to make sure the output didn't put quotes around all the text and turn the output into a single cell in the csv (this may not have been necessary at all)
8. Write BOM: Not relevant to your specific use case has to do with UTF-8 encoding (for fun though: https://en.wikipedia.org/wiki/Byte_order_mark here is a wiki article on it)
