A lightweight Chrome extension source-code project for collecting business information from result cards currently visible on Google Maps and exporting the collected records to CSV. WHAT IT DOESSearch for a business category and location on Google Maps, collect the currently visible result cards, review the extracted records in the extension popup, and export the data as a CSV file. WHAT'S INCLUDED- Complete extension source code- Manifest V3 configuration- Popup interface and styles- Business-card collection and extraction logic- CSV export page and scripts- Extension icons (16px, 48px, 128px)- Installation and customization documentation- Changelog and license REQUIREMENTS- Google Chrome or a compatible Chromium-based browser- Access to a Google Maps results page- Basic familiarity with loading and customizing an unpacked Chrome extension IMPORTANT LIMITATIONSThe extension collects result cards visible when the collection action is triggered. It does not automatically scroll through results or collect additional pages. Extracted information depends on what Google Maps displays, and some fields may be missing. Changes to Google Maps page structure may require updates to the selectors or extraction logic. This is an independent source-code project.
