Dedupe before extraction
If duplicates remain, extracted packages may contain repeated numbers. Deduping first gives cleaner batches.
Use random extraction for sampling
Random extraction is useful when testing a subset or releasing data in batches.
Use package export for team assignment
Create files by package size or package count so each person or batch gets a clear file.
Save remaining data separately
Do not lose unused data. Export remaining records for the next round or future checks.
FAQ
Can random extraction include duplicates?
Dedupe first to reduce repeated numbers in output packages.
Can package counts be checked later?
Yes. Check exported file counts and row counts.
Should App A or App B be used first?
Use App A first for regional sorting; use App B directly for dedupe and package export.
