About JSONEDIT

A simple, fast, and secure toolkit for developers who need to work with JSON data every day. Built for privacy, 100% in your browser.

Our Story

What began as a simple utility has grown into a trusted tool used by thousands of developers worldwide. We've stayed true to our core principle: keep it simple, make it work, and respect your data.

2025 Multi-language support and modern Angular v21 migration.
2026 Refreshed the interface with a cleaner, developer-focused look, moved large JSON comparisons onto a background thread so big files no longer freeze the page, and added a dedicated Settings page, Privacy Policy and Contact page.
2026 Launched Share Link for publishing JSON, YAML, XML and CSV snippets via a link, added a Tools menu for faster navigation, and published new guides on JWTs, Base64 encoding, common JSON errors and sharing JSON online.
2026 Redesigned every tool with a new light and dark theme and a shared editor toolbar (upload, format, copy, download, full-window view). Rebuilt the JSON Editor, Tree Viewer, Formatter, Schema Validator (drafts 2019-09 and 2020-12) and Mock Data Generator, added the JSON Inspector workspace and a JSON Examples library, added new editor and tree view settings, and wrote how-it-works guides with examples and FAQs for the Compare, JSONPath, JSON to YAML, Schema Validator and Tree Viewer tools.
2026 Added four new tools: JSON to XML, JSON to TOML, JSON to TypeScript and a JSON Minifier. Wrote a guide and FAQ for every remaining tool, translated all FAQs into French, Bengali and Chinese, fixed the Grid Viewer failing to load, sped up the first page load, and added tool links to the footer and Tools menu.
