Example rows with made-up values. Your file will have the columns you ask for.

Some projects need more than one table. You might need every article from twenty news sites, every product in a marketplace category, or a full copy of a site’s structure for an audit.

I plan the crawl, run it politely with rate limits so the target sites are not overloaded, and deliver a structured dataset with a short note explaining every column.

Typical outputs

  • CSV or JSON Lines files, split into sensible batches
  • Clean text with titles, dates, authors and URLs
  • A data dictionary describing each field
  • Optional upload to a database, S3 bucket or Google Drive

Questions about this service

How big can a crawl be?

I have worked with jobs from a few thousand pages to several hundred thousand. Very large crawls are split into batches so you can check the data as it arrives.

Can you clean and label the text?

Yes. I can remove boilerplate, split by section, detect language and add simple labels such as topic or date.
