Microdata to JSON-LD Converter — Free Structured Data Translator

Description:
A professional Microdata to JSON-LD Converter that runs entirely in your browser — no server-side processing, no account required. Instantly translate HTML Microdata markup into clean, valid JSON-LD schema format for improved SEO and easier structured data management.

Key Features:

• Browser-based conversion — your HTML content never leaves your device
• Microdata extraction — parses itemscope, itemtype, and itemprop attributes automatically
• Valid JSON-LD output — generates schema.org compliant structured data
• Preserves schema types — maps Microdata vocabulary to matching JSON-LD @type values
• Nested item support — correctly handles nested item properties and arrays
• Copy-ready output — grab the JSON-LD block and paste directly into your page head
• Works offline — no internet needed after page load
• Mobile-friendly — convert structured data on any device

How It Works:
Paste your HTML containing Microdata attributes (itemscope, itemtype, itemprop), and the converter automatically extracts and remaps everything into a valid JSON-LD script block. Replace the old inline Microdata with the generated JSON-LD in your page's <head> section. Google recommends JSON-LD over Microdata for structured data — this tool makes the migration straightforward.

Privacy & Performance:
All parsing and conversion runs locally in your browser. Your HTML content, including any embedded data values, never touches a remote server.
