How to scrape documents and filings data from Comcast using Minexa.ai

Comcast files regularly with the SEC, and all those filings are listed publicly on cmcsa.com. The page covers everything from 8-K material event reports to proxy statements, Form 4 ownership changes, and Schedule 13G disclosures. Getting that data into a structured format manually means copying row by row. Here is what the extracted output actually looks like, and how to get it in minutes using the Minexa.ai Chrome extension.

What the extracted data looks like

Each row in the extracted dataset corresponds to one filing entry. Below are three example rows with the key fields Minexa surfaces automatically:

[
  {
    "form": "8-K",
    "description": "Report of unscheduled material events or corporate event",
    "event_date": "Jun 12, 2026",
    "event_datetime": "2026-06-12T04:00:00Z",
    "sec_filing_link": "/sec-filings/sec-filing/8-k/0001628280-26-042848",
    "node_link": "/node/45731/html",
    "file_link": "/static-files/0b06064a-1769-4c5e-958c-e9ba4226520f",
    "view": "View HTML"
  },
  {
    "form": "SD",
    "description": "Specialized Disclosure Report",
    "event_date": "May 22, 2026",
    "event_datetime": "2026-05-22T04:00:00Z",
    "sec_filing_link": "/sec-filings/sec-filing/sd/0001628280-26-037566",
    "node_link": "/node/45626/html",
    "file_link": "/static-files/cf139da0-f37f-451c-b58c-b6d880e2acf5",
    "view": "View HTML"
  },
  {
    "form": "DEF 14A",
    "description": "Official notification to shareholders of matters to be brought to a vote",
    "event_date": "Apr 24, 2026",
    "event_datetime": "2026-04-24T04:00:00Z",
    "sec_filing_link": "/sec-filings/sec-filing/def-14a/0001193125-26-177138",
    "node_link": "/node/45506/html",
    "file_link": "/static-files/1f65c39c-0726-43a9-9cdf-544a1ea0bcf0",
    "view": "View HTML"
  }
]

The event_datetime field delivers each filing date as an ISO 8601 timestamp, which makes it straightforward to filter by date range or sort chronologically in any downstream pipeline. Each row also includes two separate static file link fields, giving access to different document versions or exhibit files attached to the same filing.

Now here is how to collect this data yourself using the Minexa.ai extension.

Step-by-step extraction guide

Start by opening the Minexa.ai home page. If you have not installed the extension yet, you can get it from the Chrome Web Store before continuing.

Navigate to cmcsa.com/financials/sec-filings. The page loads the full filings table with form types, dates, and document links all visible.

Open the Minexa.ai extension. A popup appears with a confirmation button. Click I'm on the right page to tell the extension which page to work with.

The extension detects pagination automatically. Review the detected next-page logic and click Continue to proceed.

Choose whether to scrape the filings list only or to also follow each filing link to its detail page. For most monitoring use cases, the list alone contains all the fields you need.

Select Simple scraping mode to extract the filings table as-is, or choose Advanced if you need custom interactions before the data loads.

Minexa highlights the full data container on the page automatically. Confirm the selection and click Create Scraper.

All extracted columns appear in the preview panel. Use the navigation arrows to review each data point before finalising.

Once the scraper is created, run the job and wait for it to complete. The results appear in a structured table ready for export.

Export to Excel or JSON directly from the results view. You can also connect to Google Sheets or set up a recurring schedule so the filings list updates automatically each time Comcast publishes a new document.

Install the Minexa.ai Chrome extension and run your first Comcast filings extraction today.
