Frequently Asked Questions

What is OPML and why convert JSON to it?

JSON objects become OPML outline elements, with object keys as outline text and nested objects/arrays creating hierarchical outline structures. Arrays are converted to numbered or bulleted outline items.

Will the OPML work with RSS readers?

Can I edit the OPML output before downloading?
