What is Data Miner?

Data Miner is a Google Chrome and Microsoft Edge browser extension for web scraping and data extraction without writing code. It uses pre-built extraction rules, called recipes, to pull tables, lists and other page content and export it to CSV, Excel or Google Sheets. Users can also build their own recipes, crawl across paginated results, fill forms from CSV data and run custom JavaScript to clean results. The product is developed and supported by a team based in Seattle.

Key Features

One-click recipes

Over 50,000 pre-built extraction rules let you scrape popular websites in seconds and download the result as a CSV file.

Custom recipe builder

Create your own extraction rules with the point-and-click Easy Finder tool for sites that have no public recipe.

Pagination and crawling

Automatically navigate paginated results and crawl across multiple pages to extract data in a single run.

Authenticated scraping

Pull data from pages behind a login or inside a corporate firewall using your existing browser session.

Bulk URL scraping

Provide a list of URLs and Data Miner scrapes data from each one in turn.

Custom JavaScript and API hooks

Run custom JavaScript and pre and post-scrape events to clean or transform extracted data, for example to extract emails.

Form automation

Auto-fill web forms using pre-populated CSV data, and extract table data via right-click.

Pros & Cons

Advantages

  • It runs entirely as a browser extension, so scraping uses your own logged-in session and avoids the setup of a separate scraping platform.
  • A large library of over 50,000 public recipes means many common sites can be scraped without building any rules yourself.
  • The free Starter plan allows 500 pages per month, which is enough to evaluate the tool before paying.
  • It exports directly to CSV, Excel and Google Sheets, which fits common spreadsheet-based workflows.
  • Custom JavaScript and bulk URL scraping give more technical users room to handle awkward sites and clean data.

Limitations

  • The free Starter plan is restricted on some domains and only the paid plans unlock scraping on all domains.
  • Page limits are relatively low across tiers, so high-volume scraping pushes you toward the Business Plus or Enterprise plans quickly.
  • As a browser extension it relies on your machine and browser staying open, unless you move to server-side Enterprise scraping.
  • Pricing is charged per page scraped rather than per record, which can be hard to predict for sites with heavy pagination.

Use Cases

Sales and marketing teams collecting business listings, contact details and lead lists from directories and search results.

E-commerce researchers gathering product names, prices and reviews across catalogue pages for competitor monitoring.

Recruiters and researchers extracting profile or listing data from sites that sit behind a login.

Analysts pulling tables and lists from web pages into spreadsheets without writing scraping code.

Operations staff bulk-scraping a known list of URLs and exporting the combined data to Google Sheets.
