Description
AI generated by Codex for Shai. A browser-local JSON workbench with two editors, formatting/minification, optional object-key sorting, guarded parsing, structural added/removed/changed reports, comparison downloads, editor swapping, and explicit JSON backups. Editor contents are memory-only, including in the delivered standalone source.
Editor contents remain in this tab only, on both the hosted demo and standalone source. Export a JSON backup to keep them. No contents are automatically written to browser storage.
Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.

What works
- Validate, format, minify, and optionally sort object keys in JSON
- Compare structural values while ignoring object-key order and respecting array order
- Show added, removed, and changed paths with before/after previews
- Download the difference report and export/import editor drafts as JSON backups
- Keep editor contents in memory only; no automatic localStorage or network requests
- JSON backup/import; hosted demo works in memory without network requests
What’s unfinished
- No JSON Schema validation, JSON5, YAML, merge editor, executable JSON Patch, or file upload parser
- Inputs limited to 200,000 characters, 10,000 values, 40 nesting levels, and 500 reported changes
- Numbers use JavaScript precision; unsafe integers and non-finite numbers are rejected
- Editor contents and reports are lost on reload unless explicitly exported

Technologies
HTML5, CSS3, Vanilla JavaScript ES modules
Setup requirements
Unzip source and run python3 -m http.server 8080 in the folder. Open http://localhost:8080 or deploy to a static HTTPS host. No build or API key. Node 20+ runs test.mjs. See README.md and QA.md.
Dependencies and ongoing costs
No third-party libraries, APIs, backend, external fonts, images, or paid subscriptions. Hosted demo is served by SellMyVibe. Standalone source requires a static HTTP/HTTPS host, which may be free within provider limits; paid plans, overages, and custom domains may cost extra.
Known limitations
Working prototype. No JSON Schema validation, JSON5, YAML, merge editor, executable JSON Patch, or file upload parser. Inputs limited to 200,000 characters, 10,000 values, 40 nesting levels, and 500 reported changes. Numbers use JavaScript precision; unsafe integers and non-finite numbers are rejected. Editor contents and reports are lost on reload unless explicitly exported. App data resets on reload in the hosted demo; export JSON backups. See the app description for standalone storage behavior. No independent security audit or broad device/browser certification.
