Here's one way:
You can look at has_shortcode() and find the parsing there:
preg_match_all(
'/' . get_shortcode_regex() . '/',
$content,
$matches,
PREG_SET_ORDER
);
using the get_shortcode_regex() function for the regex pattern.
For non empty matches, you can then loop through them and collect the full shortcode matches with:
$...

To change the functionality of a shortcode you must first remove_shortcode( 'shortcode_name' ); where shortcode name is the name of the shortcode. Add the shortcode back with your NEW function.
A simple example to follow what you might be needing:
remove_shortcode( 'mybutton' );
add_shortcode( 'mybutton', 'my_shortcode_function' );

If you only need the Shortcodes without the attributes, you can use this function:
function get_used_shortcodes( $content) {
global $shortcode_tags;
if ( false === strpos( $content, '[' ) ) {
return array();
}
if ( empty( $shortcode_tags ) || ! is_array( $shortcode_tags ) ) {
return array();
}
// Find all registered ...

The above solution doesn't work if you're using Advanced Custom Fields. When using ACF, the following code does work:
remove_filter( 'the_content', 'wpautop' );
remove_filter( 'acf_the_content', 'wpautop' );
add_filter( 'the_content', 'wpautop' , 99);
add_filter( 'acf_the_content', 'wpautop' , 100);
add_filter( 'the_content', 'shortcode_unautop',110 );

If you don't want to include posts in child categories, use the category__in parameter:
$args = array(
'category__in' => [ get_cat_ID( $category_name ) ], // use category__in
//'category_name' => $category_name, // and not this.
'post_type' => 'menu',
'numberposts' => -1,
'post_status' => 'publish'
);
And although ...

In order to change the shortcode value by leveraging ajax, you need to modify the PHP code and jQuery as mentioned below:
function table_generator() {
// Set product providers
$providers = array(
'Provider 1',
'Provider 2',
'Provider 3',
);
// Build provider selection form
$output .= '<form id="submitProvider" ...

Shortcode callbacks must return a string or nothing at all. They must not print anything directly, because that will create an immediate output as you have seen in your example. We have a few topics about that already. I took the liberty to reopen your question, because you said the other answers didn't really help you. :)
Almost every function that prints ...

Try :
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );
function custom_override_checkout_fields( $fields ) {
if(is_user_logged_in()){
unset($fields['billing']['billing_email']);
}
return $fields;
}
