Introduction

The Nepali Dataset Crawler fetches public webpages from Nepali web domains and normalizes their content — including text bodies, metadata, titles, publish dates, and possibly images — into a structured dataset. It’s ideal for NLP tasks, local-market research, cultural analysis, or language-specific data pipelines.

What It Helps You Do

• Crawl multiple Nepali websites quickly and at scale.
• Collect article content, metadata, and publication information.
• Build a clean text dataset for NLP, sentiment analysis, or translation projects.
• Archive web content from Nepali sources for future processing.
