Extract Data from Websites

Introduction

Dume for Chrome can turn any structured webpage into exportable, clean data. Whether it's a directory of contacts, a product catalog, a pricing comparison page, or a job board — describe what you want and Dume extracts it.

How to Extract Data

Step 1 — Open the target page

Navigate to the page containing the data you want to extract. This works best on pages with repeating structures: tables, card grids, lists, or directories.

Step 2 — Open the Dume sidebar

Click the Dume icon in your browser toolbar to open the sidebar on the current page.

Step 3 — Describe the extraction

Use plain language to describe what you need:

Extract all rows from this table. Columns should be: Company Name, Industry, Employee Count, HQ Location.

From this product page, extract: product name, price, SKU, and availability status for every item listed.

Get all the speaker names, job titles, and company names from this conference page.

Step 4 — Export

Once Dume extracts the data, you can:

• Copy as Markdown table
• Export as CSV
• Save to Notion database
• Send to a Google Sheet

What Works Well

Limitations

Dume for Chrome works with publicly accessible page content. It cannot:

• Access content behind a login it doesn't have credentials for
• Extract content that requires JavaScript interaction (infinite scroll, heavy SPAs) without additional prompting
• Bypass paywalls or access restricted content

For heavy scraping needs, consider using Dume Cowork on the desktop for more powerful automation.

Responsible Use

Only extract data from pages where it is publicly available and your use complies with the site's terms of service. Dume does not store the extracted data — it stays in your session and exports to your chosen destination.
