How to Convert Any Website Into Clean Markdown for RAG Pipelines

Developers building retrieval-augmented generation (RAG) systems often struggle with extracting clean, structured text from websites, as basic tools like BeautifulSoup strip out formatting and fail on JavaScript-rendered pages. A more robust approach combines a headless browser, a Readability parser, and a Markdown converter to preserve headings, lists, tables, and code blocks that matter to language models. The Apify-hosted Website-to-Markdown actor offers an API-based solution that handles sitemap crawling, robots.txt compliance, URL filtering, and returns structured Markdown with metadata such as title and word count. Developers can integrate the output directly into a pipeline that chunks the Markdown by headings and upserts embeddings into a vector store, with Node.js sample code provided. The service also supports PDF and DOCX files, operates on a pay-per-page model with no subscription, and can be scheduled for nightly re-crawls to keep embeddings current.
