What Is a JSON Feed?
A JSON Feed is a web feed format that uses JSON instead of XML to publish frequently updated content such as blog posts, news articles, or podcasts. JSON Feed (version 1.1) is simpler and more machine-friendly than RSS or Atom while providing the same syndication capabilities.
This is used for:
- Blog Syndication: Publish your blog as a JSON Feed so feed readers and aggregators can consume it.
- Podcast Distribution: Distribute podcast episodes with attached metadata using the JSON Feed podcast extensions.
- API Content Feeds: Serve content updates as a standardized feed that any JSON Feed reader can parse.
How to Use the JSON Feed Validator Online

- Click Validate: The tool checks for required fields (
version,title,items), validates data types, and lists any missing recommended fields. - Review the report: Fix any errors or warnings, then re-validate until your feed passes all checks.
