Bulk import Pio ranges

Choose a ZIP or a folder (including subfolders). Preview the categories, then import. Existing ranges within the same collection are skipped. Each ZIP or folder gets its own collection. Zero-only and invalid ranges are reported and skipped.

Classification examples

Action files for the same decision are grouped automatically. Low RNG selects the most aggressive action: all-in, larger raises, smaller raises, call/check, then fold. Original action files remain available below for editing.
