Exporting to DraftKings & FanDuel
The toolbar above the lineup cards handles everything that leaves the app. There are two distinct workflows: a plain lineup export, and the mass-entry Upload → Fill flow.
Export — plain lineup CSV
Export downloads your lineups as DK_lineups_<date>.csv (or
FD_lineups_<date>.csv on FanDuel). For MLB Classic the DK header is
P,P,C,1B,2B,3B,SS,OF,OF,OF with DraftKings player IDs in the cells —
exactly what DK's bulk lineup upload expects. Randomize is the same
export with the lineup order shuffled.
Upload → Fill — mass-entry files
If you've already reserved contest entries, download the entries file from DraftKings (or FanDuel) — the one with Entry ID, Contest Name, and Fee columns — then:
- Click Upload CSV and pick that file. The button turns green and shows the entry count.
- Click Fill. Your lineups are written into the entry rows — Entry ID,
contest, and fee preserved — cycling through your lineup set if there are
more entries than lineups. Downloads as
DK_entries_filled_<date>.csv. - Rand Fill does the same with the lineup order shuffled first.
Re-upload the filled file on the DFS site to set all entries at once.
The build bar's other Export
The Export button in the bottom build bar is different: it downloads the
current player pool (projections, salaries, ownership) as
<Slate>_player_pool.csv — a data export, not lineups.
FanDuel MLB rules differ from DraftKings: a $35,000 cap and at most 4
batters per team. The FD export/fill paths handle FD's
id:Name cell format automatically.
Keep the platform toggle matched to where you're entering. Exported IDs are platform-specific — a DK file will not import into FanDuel.
