The plugin had some bugs the author didn't seem to care about, and did not allow for the changing of the delimiter in CSV files - this was a pretty critical problem as clients using excel have a REALLY hard time opening files delimted with anything other than a comma.

Known issues

The current code will run on Woocommerce 3.0+ stores, but contains a lot of anti-patterns - most commonly that meta information regarding products is currently updated via the update_post_meta() function, rather than utilising the new Woocommerce Data Stores to manage the product data.

Changing the delimited

<?php

// Define a custom delimiter, standard is now ','
define('WC_STOCK_CSV_SEPERATOR', ';');
