Views field template is ignored in CSV export

Also seeing this issue, but I am not even seeing the templated output on the views display preview. Should this work? Thanks

Is it possible to get an answer here? Should normal view field templates work here just like any other view? I am not seeing that, and I just want to be sure Im not doing anything wrong, so I dont waste anymore time, but no matter what I do, I cannot get theme template files here to do anything.

Thanks

This seems to be related to this issue ✨ Views hooks not executed Fixed .
The data export display is not being rendered and therefore some hooks are not executed. The views data export module includes a hook for this: hook_views_data_export_row_alter
Here is an example:

function my_module_views_data_export_row_alter(&$row, \Drupal\views\ResultRow $result, \Drupal\views\ViewExecutable $view) {
  if ($view->id() == 'my_view') {
    $node = $result->_entity;  // Get the node object
    $data = getData($node);

    foreach ($row as $key => &$value) {
      if (str_contains($key, 'nothing')) {
        $value = setCustomValue($data, $key);
      }
    }
  }
}
