I use this if it helps@

function custom_field_excerpt() {
	global $post;
	$text = get_field('overview');
	if ( '' != $text ) {
		$text = strip_shortcodes( $text );
		$text = apply_filters('the_content', $text);
		$text = str_replace(']]>', ']]>', $text);
		$excerpt_length = 10; // 20 words
		$excerpt_more = apply_filters('excerpt_more', ' ' . '...');
		$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
	}
	return apply_filters('the_excerpt', $text);
}
function custom_field_excerpt_longer() {
	global $post;
	$text = get_field('overview');
	if ( '' != $text ) {
		$text = strip_shortcodes( $text );
		$text = apply_filters('the_content', $text);
		$text = str_replace(']]>', ']]>', $text);
		$excerpt_length = 25; // 20 words
		$excerpt_more = apply_filters('excerpt_more', ' ' . '...');
		$text = wp_trim_words( $text, $excerpt_length, $excerpt_more );
	}
	return apply_filters('the_excerpt', $text);
}

Just ensure you change this bit to your field name:
$text = get_field('overview');

Then to call it I use:
<?php echo custom_field_excerpt_longer(); ?>

Cheers
