raffle-winner-picker is a skill that randomly selects fair giveaway winners from spreadsheets, Google Sheets, or lists with cryptographic randomness and transparent timestamps.

About

Raffle Winner Picker is a Composio skill for fair random winner selection from lists, spreadsheets, or Google Sheets during giveaways and contests. It picks one or multiple winners with duplicate prevention so the same person cannot win twice. Sources include Google Sheet URLs, local CSV or Excel files, and inline name lists. Features cover cryptographically secure randomness, transparent results with selection method and UTC timestamp, exclusion of previous winners, optional weighted selection by entries column, and runner-up picks. Example output reports total entries, selected row number, winner name and email, entry metadata, and options to pick another winner or export details. Workflows span social media giveaways from Google Form exports, event raffles from attendee CSV files, and random team assignment splits. Tips emphasize documenting timestamp and method, public announcement, eligibility verification, runner-ups for ineligible winners, and exporting results. Privacy notes confirm no manipulation, recorded timestamps, optional verification seed, and data privacy respect.
