functions - How to Programmatically Replace Characters in WooCommerce Product Slugs?

I'm trying to adjust the URL structure of my WooCommerce product slugs by replacing specific characters programmatically. Here's my current situation:

Product Title: Desk Flag 15x22,5 Cm

Current slug example: /product/dek-flag-15x225-cm-masa

Desired slug example: /product/dek-flag-15x22-5-cm-masa

As you can see, I want to replace 22,5 in the slug with 22-5. I tried several approaches, including using the wp_insert_post_data filter to modify the slug during product creation or updates, but I couldn't get it to work as expected.

Here’s the code I attempted:

    function custom_product_slug_replace_comma($slug, $post_ID, $post_status, $post_type) {
    // Sadece WooCommerce ürünleri için çalıştır
    if ('product' === $post_type) {
        // Virgülleri (-) ile değiştir
        $slug = str_replace(',', '-', $slug);
    }
    return $slug;
}
add_filter('wp_unique_post_slug', 'custom_product_slug_replace_comma', 10, 4);

However, the slug remains unchanged after saving the product. I also want to ensure existing product slugs are updated to match the desired format.

Could someone guide me on how to achieve this properly? I'm open to either a dynamic solution that works for all future products or a one-time script that updates existing slugs.

Thanks in advance for your help
