There is a thread within our customer only forums where members of the community have discussed this and others similar such as " Easy Lead Finder v2". It seems some have had success with these in terms of importing listings, but with some additional fiddling required in order to import data correctly. There is also some question around whether or not Google "likes" sites which have obtained data in this manner. Ultimately Vantage has a built in .csv importer, so if you can convert data into that format, you can import it. Thanks.
