Sorry for replying to a 2 year old post. I agree that trimming fields should be included in the plugin. But the code posted by Radovan didn’t worked for me, since I also have checkboxes (in the end the ACF values aren’t strings but an array, and former code fails).

Here is a slightly improved code for anyone stumbling on this page

function trim_acf_fields( $post_id )
{
  // load from post
  if( isset($_POST['fields']) ) {
    foreach($_POST['fields'] as $key => $value) {
      if(!is_array($value))
        $_POST['fields'][$key] = trim($value);
    }
  }
}
// run before ACF saves the $_POST['fields'] data
add_action('acf/save_post', 'trim_acf_fields', 1);
