Update stock status from url

Hi,

I’m trying to update the stock status on my online shop using the feeds from our suppliers. Unfortunately they don’t have the exact stock quantity in the file. They have mentioned if the product is in stock or out of stock but the value is different from the default stock status value from woocommerce (instock and outofstock)
Is there a solution to update the stock status from URL (xml or csv file) if the file has different term than “instock” or “outofstock”?
Thank you for support!
