About these tools
These editors are for the moments when installing something would take longer than the task itself: formatting a JSON payload, diffing two versions of a paragraph, checking a snippet with syntax highlighting, or testing whether a SCORM package actually reports completion.
Everything stays in the browser tab. The JSON formatter validates and pretty-prints without sending your payload anywhere, and the SCORM debugger runs the package locally against a mock LMS API so you can watch the calls it makes in real time.
Frequently asked questions
Is my text or code sent to a server?
No. Every editor here runs client-side; nothing you type is transmitted or stored.
Which SCORM version does the debugger support?
SCORM 1.2. It logs every LMS API call the package makes and shows the resulting CMI data model.
Can I save my work?
Use the export or download option in each editor. Since nothing is stored on our side, closing the tab discards unsaved content.
