Hey @sefiani ,
Many many thanks. I just started with my new store over 5000 products, i thought of doing this step at the end and it was giving me a headache to even think of doing it. I just searched on shopify if someone write me a script like this, but i found your app.
Much Much needed. Thankyou so much in advance.
