JsonForge

JSON swiss army knife. Six operations in one tool: deep structural validation (11 rules catching issues JSON.parse considers valid), wildcard dot-notation queries (users.*.email), two-file diff with path-level detail, flatten to dot-notation, format/pretty-print, and minify. Catches empty containers, null in required fields, duplicate keys, mixed array types, inconsistent object keys, and embedded JSON strings. HTML, JSON, text output. CI/CD ready. Zero dependencies. Single Python file.
