Stop separate data with “|” symbol between text

When I want to import Woocommerce products with variable products, WP All import separate’s data from the import.

For example some variable attribute data with this text will be separated

Kolibri Greens | Groene plant – Rhipsalis Cereuscala Gold – potmaat Ø9cm – groene kamerplant – vers van de kweker

It will be importe as,

Kolibri Greens, Groene plant – Rhipsalis Cereuscala Gold – potmaat Ø9cm – groene kamerplant – vers van de kweker

So 2 variations, but it should be just one.

Any advise or help is appreciated, I tried this code below, but it only changes the delimiter.

function my_replace_delimiter( $data ) {
return str_replace( '|', '', $data );
}

Thanks, Greets!
