csv-excel-merger

Quick Review

Excellent skill for merging CSV/Excel files with comprehensive guidance on column matching, conflict resolution, and deduplication. The description clearly defines when to invoke the skill, and the instructions provide detailed step-by-step procedures covering analysis, matching strategies, conflict resolution approaches, and quality reporting. Includes concrete Python/pandas code examples and well-formatted output templates. The skill addresses a moderately complex task that would otherwise require significant token usage to solve from scratch, though similar functionality exists in common data tools. Structure is clear with logical progression from file analysis through execution to reporting. Minor improvement areas: could benefit from modular file separation for large code snippets, and the novelty is somewhat limited as pandas merge operations are relatively standard, though the intelligent column matching and comprehensive conflict resolution adds meaningful value.
