Field notes
Rowwise compares a baseline file with an updated file after the user selects one or more matching-key columns. It treats case, whitespace, and data type as significant, while allowing columns and specific old-to-new value changes to be excluded. Repeated or empty keys receive a Duplicate status, and exports preserve the review: Excel uses yellow highlights while CSV supplies status and changed-column labels.
