Merge CSV Records for Clean Data Handoffs
Sunil Kalikayi4/9/20265 min read
Handoffs Need a Single Source of Truth
When two teams maintain related CSVs, merging them creates one cleaner handoff file. That makes it easier to review the final dataset and spot gaps.
Use the Join that Matches the Goal
Choose inner joins for overlaps, left joins to preserve the primary list, and outer joins when completeness matters more than compactness.
Verify the Merge Key
The merge key should be stable and unique. If the key is weak, the merged file may contain duplicated or misaligned rows.
Review Before You Share
A quick preview helps confirm the merge worked the way you expected. That final check reduces surprises when the file reaches the next team.
