Collection associated with product not displaying

I recently shifted to a new shopify theme and transfered all data via csv to new theme. At the same time, Collections were created in new theme with same name as in previous.

Issue is , example an X product was in a particular 2 collections which were manually selected in previous theme, but while exporting the product data from old theme, its neither appearing in csv file nor reflecting in new theme , even though drop down menu of collection is there at product page as i already imported the collection names.

So say i have 500 products in store, does that mean i need to manually select the collections again in each of the product or there is a way out of this ?

Hi @grainsandpixels

It is possible through product CSV

https://help.shopify.com/en/manual/products/import-export/using-csv

In the document check for heading collection exception, you can add this column to exported CSV and then reimport again after adding collection to each product.

Please take a backup of CSV so that you didn’t loose the original CSV in case of issue

Thanks!
