The Problem: Real-World Data Is Messy
Customer names, company names, product descriptions, and addresses rarely match perfectly between systems. Someone types "Microsoft Corporation" in one system and "MSFT" in another. Sales reps abbreviate. Data entry has typos. Manual matching wastes hours and introduces errors.
Common Data Matching Challenges
Before we dive into the solution, here are the typical issues that make column matching difficult:
| Challenge | Example from File 1 | Example from File 2 |
|---|---|---|
| Typos | John Smith | Jon Smtih |
| Abbreviations | International Business Machines | IBM |
| Extra Spaces | Apple Inc. | Apple Inc. |
| Case Differences | MICROSOFT CORP | Microsoft Corp |
| Missing Words | The Coca-Cola Company | Coca-Cola |
| Format Variations | 555-123-4567 | (555) 123-4567 |
