What problem does it solve?

This Skill automates the complex task of merging multiple CSV/Excel files, intelligently handling different schemas, deduplicating data, and resolving conflicts. It saves data analysts and business users hours of manual data cleaning and consolidation.

Core Features & Use Cases

  • Intelligent Column Matching: Automatically map similar columns across different files, even with inconsistent naming conventions.
  • Data Deduplication: Identify and remove duplicate rows based on primary keys (e.g., email address), ensuring a clean dataset.
  • Conflict Resolution: Define strategies for handling conflicting data when the same record appears in multiple files (e.g., keep latest, keep longest).
  • Use Case: A marketing analyst has customer data spread across three different CSV files with inconsistent column names. This Skill merges them into a single, clean file, deduplicates entries, and resolves data conflicts, ready for analysis.

Quick Start

Example: Merge CSV files

"Merge these two CSV files: 'contacts_q1.csv' and 'contacts_q2.csv'. Use 'email' as the primary key for deduplication. Handle conflicting 'phone' numbers by keeping the most recent."
