How the RSS to OPML Generator Works

What the Tool Does

The RSS to OPML generator creates OPML (Outline Processor Markup Language) files from a list of RSS feed URLs. OPML files are the standard format for exporting and importing RSS feed subscriptions between different feed readers and applications. This tool takes your RSS feed URLs and automatically generates a valid OPML 2.0 XML file that you can import into any feed reader or RSS aggregator. The generator supports organizing feeds into categories, adding custom titles for each feed, and creating properly formatted OPML files ready for use.

Common Developer Use Cases

Developers use RSS to OPML generators when setting up feed subscriptions for applications, creating backup files of their feed lists, or sharing curated feed collections with others. This tool is particularly useful when migrating between feed readers, setting up RSS aggregation services, or managing feed subscriptions programmatically. Many developers find it valuable when working with content management systems, news aggregation platforms, or building custom RSS reader applications that need to import feed lists in OPML format.

Input Formats

The generator accepts RSS feed URLs in multiple formats: one URL per line, comma-separated URLs, or URLs with optional titles in the format "Title|URL" or "Title:URL". The tool automatically validates each URL to ensure it's a valid HTTP or HTTPS link before including it in the OPML output. You can also organize feeds into categories by using the category organization feature, which groups feeds by their assigned categories in the generated OPML file.

OPML Output

The generated OPML file follows the OPML 2.0 specification and includes all necessary metadata such as the document title, creation date, and properly formatted outline elements for each RSS feed. The output is valid XML that can be imported into any feed reader application, including popular tools like Feedly, Inoreader, NewsBlur, and many others. You can download the OPML file directly or copy it to your clipboard for easy sharing.

Related Tools

This generator complements the OPML RSS URL Extractor, which performs the reverse operation by extracting RSS URLs from OPML files. For working with XML files, try the XML to JSON converter or the XML formatter. For validating XML structure, use the XML validator.
