Where it helps
Inconsistent spreadsheets make it difficult to compare records or prepare dependable reports. Cleanup is most useful when the team can agree how fields should look and which issues require a human decision.
How the work takes shape
NexSar applies the agreed rules to one dataset and records unresolved cases separately. Transformation notes explain the changes so a data owner can review them or repeat the procedure.
Example engagement
An operations team preparing a supplier list for analysis could normalize names and dates, flag possible duplicates, and review the remaining exceptions before use.
