DFS exposure calculator

Open your DraftKings or FanDuel lineups file, and see how many of your lineups hold each player. It is free, with no account. The file stays on your device: this page sends it nowhere.

Which files work?

• The DraftKings entries file (DKEntries.csv), with your lineups in it.
• A DraftKings upload file: a first row of roster slots, and one lineup on each row.
• The FanDuel entries file (the CSV Edit template), and the FanDuel upload file.

A cell can hold a name with its ID ("Josh Allen (44249122)") or an ID only. A file with IDs only shows the names when it has the site's player list, as the entries files do. An entry with no lineup does not count.

What is exposure?

A player's exposure is the share of your lineups that hold him. If 8 of your 20 lineups hold one player, his exposure is 40%. On a Showdown or a single game slate, the calculator also counts each player's lineups as the captain or the MVP.

What is a stack?

A stack is a lineup with 2 or more players of one team, such as a quarterback and his receivers. On a Classic slate, the calculator counts your lineups with 2, 3, and 4 or more players of each team. It needs the teams from the site's player list, which the entries files have.

How do I set a max exposure?

DFS Studio's optimizer takes a max exposure for each player and for all players when it builds your lineups, and it fills your entries file with them. Build lineups tells how.
