Note that “prices” in this case means only numeric values that are prefixed by a currency symbol (e.g. $, £, ¥, etc). If there's a demand for it, we may in the future offer an extract option that also gets all “currency-like-but-not-currency-symbol-prefixed” values as well. In the meantime, please see EXTRACTNUMBERS() if you’d like to get all number-like entities from your text.
