WHY PROFILE FIRST
Make the invisible parts of a file visible.
A file can look fine in a spreadsheet while hiding sparse columns, duplicate rows, mixed data types, unexpected cardinality or identifiers that are not actually unique.
RowMend's profiler is deliberately descriptive: it helps you inspect the dataset before deciding what to clean, validate, import or reconcile.
