A really simple example isn’t really possible because there are a lot of moving parts, I might be able to give a better outline.

// create an acf/save_post action
add_action('acf/acf_save_post', 'import_json_for_field_group_XX', 2);
function import_json_for_field_group_XX($post_id) {
  // first to a check of the post type
  if (get_post_type($post_id)) != 'your-post-type') {
    // not our post type
    return;
  }
  // check the radio field to see if it is set to the manual value
  if (get_field('your-radio-field-name', $post_id) == 'manual') {
    // not doing import
    return;
  }
  
  // you may need to set up a field name => key reference array
  // when importing you need to use the field keys
  // either that of the file you are importing from
  // must use the field keys in the JSON
  $fields = array(
    'field-name-1' => 'field_123456',
    'field-name-1' => 'field_234567',
    'field-name-1' => 'field_345678',
    'field-name-1' => 'field_456789'
  );
  
  // doing an import
  // get the JSON field
  $json = get_field('json-input-field', $post_id);

  // at this point I'm not sure what to do
  // it depends on where the json file is stored
  // you need to use PHP and maybe some WP functions
  // find, open and get the contents of the file
  // and store the content is a variable, I'll use $contents

  $values = json_decode($contents, true);
  
  // loop thought the fields in $values and update them
  if ($values) {
    foreach ($values as $field => $value) {
      // update the field
      // note that I am using the field key reference array I created above
      // if you are importing with field keys this would not be needed
      if (isset($fields[$field])) {
        update_field($fields[$field], $value, $post_id);
      }
    } // end foreach $value
  } // end if $values

  // finally alter the radio field to manual
  update_field(('your-radio-field-name', 'manual', $post_id);
}
