About Format Hubs

Format Hubs is a developer toolbox that runs entirely in your browser. Format JSON, validate XML, decode JWT, encode Base64, and more — without sending your data to any server.

Who maintains Format Hubs?

Articles, guides, and tool documentation are produced and reviewed by the Format Hubs Editorial Team. We focus on practical developer workflows: parsing API payloads, validating configuration files, and debugging data formats in production and during code review.

How we verify accuracy

• Tool behavior is tested against official specifications such as RFC 8259 (JSON), RFC 7519 (JWT), and W3C XML standards.
• Guides are checked against real parser and formatter output before publication.
• When standards or common tooling change, we update affected pages and note material revisions.
• Each article lists primary references so readers can confirm claims independently.

Why Format Hubs?

• Privacy-first: all processing is local
• Fast: no server round-trips
• Clean UX: minimal ads, no clutter
• Dedicated pages for every tool with in-depth guides and examples

Roadmap

Phase 1 includes JSON, XML, Base64, and JWT tools. Phase 2 adds SQL, YAML, CSV, and URL utilities. Phase 3 brings AI JSON repair, code generators, and a browser extension.
