Something like this (very simplified):

  let $array := [{"foo":0,"bar":"tztz"},{"foo":"hello","bar":null},{"foo":true,"bar":"yes"}]
  let $value := for $object in $array
                return
                  let $fields := bit:fields($object)
                  let $len := bit:len($fields)
  
                  for $field at $pos in $fields
                  return if ($pos < $len) then (
                    $object=>$field || ","
                  ) else (
                    $object=>$field || "\n"
                  )
  return string-join($value,"")

will output:

  0,tztz
  hello,null
  true,yes

You could do something like this in pure python without the json loading boilerplate with jello[0]. An interactive TUI for jello called jellex[1} is also available. (I am the author)

JSON loading boilerplate? Is it also a compiler with sophisticated optimizations during compile time? :)

Of course you can simply create a module with something like the above snippet as a function for reuse. Or I can add a built-in function for flattening like this or as in pandas.
