+# Code-Syntax-Expanded
+
+A **massive, high-quality synthetic dataset** for training LLMs to identify and correct syntax errors across **33 programming languages**. Contains **5+ million unique examples** (~1.1 GB) with English explanations – no artificial padding, no duplicate rows.
+
+---
+
+## 📊 Dataset Overview
