Data Cleanup tips

🧹

For customer data deduplication, paste a column (e.g. emails or phone numbers) — find collisions before running joins.

💡

For log file analysis, the "Count occurrences" mode quickly tells you the most-frequent log entries.

🎯

For database row deduplication, export to a single-column list, find duplicates, then craft a DELETE query for them.
