How to bring different spellings of the same product property to a single view in a smart filter when importing into 1s Bitrix?

Question

1C-Bitrix

Friends, please tell me the answer or solution to the problem. We import a lot of spared goods into the online store, for example, laptops. The laptop has a "RAM" property, by which we want to filter products, but the problem is that in different products, it can be written differently, for example: 4GB, 4GB, 4GB, 4GB, 4GB, 4GB, 4GB . Accordingly, when importing in the product filter for the "RAM" property, different spellings of the same amount of RAM will appear. How can this be avoided? Normalize product properties before importing to the store or is there another simple way?

Answer 1

Of course lead to one form before import.
The main argument for this is that you will do it once, but if you load them as is and group them in a smart filter, then this is an extra load on each hit, and a smart filter is not a fast thing anyway. Plus, excessive complication, because in addition to the filter, there will be direct filtering of goods, and then you want to turn on the faceted index to speed up.

Answer 2

Unambiguously lead to a single form. Moreover - to make the field numeric and remove the units from it.
