How to split large Excel files in Node.js: a beginner's guide

Node.js enables developers to execute JavaScript outside browsers. A beginner's guide demonstrates splitting large Excel files into smaller documents with consistent header rows using short scripts, specifically addressing memory limitations for massive files.

This ensures the server remains responsive even when multiple users send requests simultaneously or when waiting for database responses without blocking the entire execution thread.
