Giveaway Entry List Checklist
Before drawing, confirm the file encoding and column, freeze the closing time, validate eligibility, apply one duplicate rule, count the final entries and retain a protected backup. The picker should receive only the identifier needed to distinguish entries.
Recommended process
- Export the source list after entry closure.
- Check headers, blank rows and UTF-8 characters.
- Apply eligibility and duplicate rules consistently.
- Compare the final count with the imported picker count.
Worked example
An exported CSV contains email, address and entry ID columns. The organizer creates a draw file containing only entry IDs, removes blank rows, verifies the count and keeps the sensitive source file outside the picker.
What to check before using the result
- Do not upload unnecessary personal fields.
- Keep a backup before cleaning the list.
- Test the import format with non-production rows first.
How the random step is handled
Random Picker Tools uses the browser Web Crypto API for selection, rejection sampling for unbiased integers and a Fisher–Yates shuffle for complete list orders. The organizer still controls eligibility, duplicate rules, consent, accessibility and legal requirements.
Privacy note
Normal picking and shuffling happen in the browser. Use initials or non-sensitive identifiers when possible, avoid unnecessary source data, and create a share link only when temporary server storage is appropriate.
