Just Upload as normal — we'll do the rest.
You don't have to worry about duplication - RotoTracker will take care of this for you. Just upload your CSV files as normal and our systems will detect what's new.
Things are even simpler with RotoTracker Sync, our browser extension. This will detect what's new locally, and only send up the latest results. If you have very large multi-megabyte files, this can speed up the process a lot.
