Bulk RSS Feed Subscriber Importer

WHAT IT DOES Bulk RSS Feed Subscriber Importer solves a common feed management challenge: subscribing to multiple RSS feeds is tedious when done one at a time in most RSS readers. While many readers support OPML import, generating an OPML file from a list of feeds requires manual creation. This tool lets you enter a list of RSS feed URLs and validates each one, extracting the feed title, description, and site URL. All feeds are displayed in a scrollable checklist with titles, URLs, and validation status. You can select multiple valid feeds and export them as an OPML file for bulk import into any RSS reader (Feedly, Inoreader, NewsBlur, etc.), or export as CSV or JSON. Progress tracking shows each validation as it completes, and a preview shows your selection before exporting. WHERE IT RUNS This extension panel runs directly inside your browser as an overlay on any web page. It works independently of any specific site and requires no additional API keys or permissions beyond the BotGentz extension. The tool fetches feed content to validate and extract metadata, making it usable from any browser session. HOW TO USE After installing the BotGentz extension and activating Bulk RSS Feed Subscriber Importer, click the extension icon in your browser toolbar to open the panel. Enter your RSS feed URLs in the text area — you can separate them by commas or new lines. For example: "https://feeds.feedburner.com/example, https://example.com/feed, https://news.ycombinator.com/rss" or each on its own line. Click "Validate Feeds" to check each URL. The tool fetches each feed, validates it, and extracts the title, description, and site URL. Results appear with color-coded status indicators: green for valid, red for invalid. Select the feeds you want to export using the checkboxes (invalid feeds are automatically disabled). Choose your export format: OPML (for RSS readers), CSV (for spreadsheets), or JSON (for structured data). Click "Export Feeds" to copy the data to your clipboard. You can then import the OPML file into your RSS reader. TECHNICAL OPERATION — Feed Validation and OPML Generation This tool fetches each feed URL using GM_xmlhttpRequest and validates the response by checking for RSS or Atom feed structure (presence of , , or tags). It extracts the feed title from the tag, description from the tag, and site URL from the tag. Invalid feeds (non-RSS content or HTTP errors) are marked with a red status indicator and are excluded from export. For export, the tool generates an OPML file following the OPML 1.1 specification, with each feed as an outline element containing the title, feed URL (xmlUrl), and site URL (htmlUrl). The OPML file can be imported into any RSS reader that supports OPML import. CSV and JSON exports are also supported for users who prefer to manage feed lists in spreadsheets or programmatically. THE PANEL The extension panel is fully draggable and remembers its position per site session. It snaps to the nearest edge of the browser viewport when dragged within 50 pixels of any side. You can collapse the panel to a compact title bar using the minimize button, preserving your selection state. The panel resizes vertically by dragging the bottom edge. Press the Escape key to close the panel instantly. The preview updates in real-time as you enter feeds or select items. PLEASE NOTE This tool requires the free BotGentz extension to function. The script fetches each feed URL to validate it and extract metadata. It does not store, transmit, or log any feed data, URLs, or user activity. All operations are performed locally in your browser session. Feed validation checks for RSS/Atom structure but does not verify the authenticity or security of the feeds. Some feeds may require authentication or may be blocked by CORS; these will appear as invalid. OPML export is compatible with most RSS readers including Feedly, Inoreader, NewsBlur, and others. The tool uses a 300ms delay between feed validations to prevent rate limiting. Export formats include OPML, CSV, and JSON for maximum compatibility with different use cases. Always verify feed URLs before importing into your RSS reader.
