About OPML files

.OPML stands for Outline Processor Markup Language. It is an XML-based format used primarily for structured outlines and exchanging lists of RSS feeds, podcast subscriptions, and blog rolls. Software like NetNewsWire, Dynalist, and tools from The Omni Group rely on .OPML to import and export hierarchical user data. Even YouTube subscriptions can be handled via this markup format.

While widely supported by feed readers and outliners, .OPML is highly disadvantaged when it comes to human readability and data portability outside of specialized tools. It is plain text formatted with strict, nested XML tags, making it visually overwhelming to read or edit manually in a standard text editor. Furthermore, standard spreadsheet tools like Microsoft Excel cannot natively parse nested .OPML structures into neat rows and columns without complex data mapping.

To make this data usable across different platforms, you often need to convert it. Just drag and drop your file here to convert it. For data analysis, bulk editing, or importing into a database, convert to CSV or JSON. For human reading, archiving, or sharing a simple list, convert to TXT or PDF. Keep in mind that converting to flat data formats like CSV may result in the loss of complex, multi-level hierarchical nesting present in the original outline.
