JSON to HTML Menu Converter
Convert nested JSON data into semantic, accessible HTML5 navigation menus. Customize class names, map keys dynamically, and generate production-ready CSS.
About
Improperly structured navigation data can cripple user experience and SEO crawling efficiency. A broken JSON object or a malformed HTML nesting structure often leads to "ghost" links or unclickable dropdowns. This tool eliminates that risk by algorithmically converting raw JSON data into compliant, semantic HTML5 lists.
We utilize a recursive traversal algorithm f(n) that iterates through every node n to unlimited depth. Unlike basic string replacement, this ensures proper closing tags and valid parent-child relationships, even for complex Mega Menus. The generator automatically applies ARIA roles, ensuring your navigation meets WCAG 2.1 accessibility standards out of the box.
Formulas
The core logic uses a recursive function to traverse the JSON tree. Let J be the input JSON array.
Reference Data
| Standard | Description | HTML Structure |
|---|---|---|
| Flat Menu | Single-level list, ideal for footers or simple headers. | <ul><li>...</li></ul> |
| Dropdown | Two-level hierarchy. Parent items toggle visibility of children. | <li><a>Parent</a><ul>...</ul></li> |
| Tree View | Multi-level nested lists, commonly used for sidebars or file explorers. | Recursive <ul> nesting. |
| Mega Menu | Complex structure often grouping items by category or columns. | Requires CSS Grid/Flexbox on the container. |
| JSON Recursion Limit | Browser stack size limit (approx 10,000 calls). | Safe for typical menus (depth < 50). |
| Accessibility | WAI-ARIA compliance for screen readers. | Attributes: aria-expanded, role="menu". |
