Short answer: Use the browser extension, RotoTracker Sync.
Importing lots of data can take a long time to do manually, particularly with FanDuel, which only allows you to download 1000 contest entries per file. If you have tens or hundreds of thouands of results, this can take a long time!
Thankfully, RotoTracker Sync does all this for you. With one click, the browser extension will download each 1000-line file in turn, combine them, and send it all up to RotoTracker in one go.
