JSON Viewer
Validate, format, minify, search, and explore JSON as a collapsible tree. Handles files up to 10 MB without uploading them.
Open JSON Viewer/srv/datademon/tools
Useful tools.
Zero uploads.
Fast browser tools for inspecting data and checking changes. No account, no server round-trip, and no complicated workflow—just paste, inspect, and keep moving.
Text Compare
Compare two texts or files with side-by-side and unified views, inline changes, ignore options, and downloadable diffs.
Open Text Compare/why/local
Developer tools should get out of the way.
Private by design
Your JSON and text are processed locally. Input content is not sent to Data Demon or included in analytics events.
Built for speed
There is no application framework or server-side processing. Large operations use dedicated browser workers to keep the interface responsive.
