Success! I messed around with the code for Product Importer Deluxe version 2.4 and I was able to get both the “quantity” and “quantity_limited” to import successfully. Here are my alterations, beginning at line 1050:
‘special_price’ => $wpsc_special, // added a comma at the end of this line
‘quantity’ => $wpsc_quantity, // added this new line
‘quantity_limited’ => ‘1’ // added this new line
That’s all there is to it! I hope this helps everybody!
Now I just need to figure out how to import all my custom meta fields.
