Powerful OPML to JSON Converter – Clean Output in 1 Click

If you’ve ever faced the hassle of turning OPML files into formats like JSON, you’re not alone. Whether you’re a developer managing feed lists, a content strategist migrating subscriptions, or a data analyst working with outlines — this Free OPML to JSON Converter makes the process effortless, fast, and accurate.

What is OPML to JSON Conversion?

OPML (Outline Processor Markup Language) is an XML-based format commonly used to store hierarchical data, such as RSS feed lists or outlines from note-taking apps like Workflowy, Roam Research, or Notion.
JSON (JavaScript Object Notation), on the other hand, is a lightweight and widely-used data format for APIs, JavaScript development, and modern applications.

Converting OPML to JSON ensures your data is flexible, easy to integrate, and ready for use in multiple platforms without tedious manual restructuring.

Who Should Use This OPML to JSON Converter?

This tool is designed for:

• Developers – Quickly parse OPML feeds into workable JSON structures for apps or sites.

• SEO Professionals – Export/import feed data for platforms like WordPress, Feedburner, or Netvibes.

• Researchers & Content Creators – Adapt outlines from apps like Notion or Workflowy into web-friendly formats.

• Educators – Share structured reading lists or RSS collections.

• Anyone working with hierarchical data – Streamline migrations, backups, or integrations.

Why This OPML to JSON Tool Stands Out

1. No Installation Required

It’s a fully web-based tool — no downloads, no plugins. Simply paste your OPML content or upload a file and get your JSON instantly.

2. Flexible Input Methods

You can:

• Paste raw OPML/XML text into the editor.

Both options give quick, accurate results.

3. Clean, Readable JSON Output

The converted JSON is formatted and indented, making it easy to use in code editors, spreadsheets, or APIs.

4. Beginner-Friendly & Developer-Ready

Even if you’ve never heard of OPML or JSON, the tool walks you through the process. Developers can integrate the output directly into their workflows.
