raffle-winner-picker

Provide the Google Sheet URL and ask for a random winner selection. The skill reads all entries, counts them, and returns one cryptographically random row with the winner's name, email, and entry details plus a timestamp.

Specify the number of winners needed and request no duplicates, for example picking 5 winners from an entries CSV. The selection ensures the same person cannot win twice in a single draw.

Yes, list the previous winners to exclude when requesting a new selection. The skill removes those names from the eligible pool before performing the random draw.

Yes, weighted selection is supported based on a column such as entry counts, where each entry counts as one ticket. Participants with more entries receive proportionally higher probability of winning.

The skill works with CSV files, Excel spreadsheets, Google Sheets, and plain text lists of names and emails. You provide the source and it parses the entries before selecting.

Selection uses cryptographically secure random number generation with a recorded UTC timestamp. A seed can be provided for third-party verification, making the process transparent and repeatable.
