FAQ
What is the difference between JSON-LD and Microdata?
Both are ways to add structured data (schema.org markup) that search engines read — JSON-LD is a separate `<script>` block, while Microdata is inline `itemscope`/`itemprop` attributes woven directly into your visible HTML. Google supports and recommends both.
Why would I want Microdata instead of JSON-LD?
JSON-LD is generally easier to maintain since it's separate from your markup, but some CMS templates or legacy systems make it easier to add inline attributes to existing HTML than to inject a script block — Microdata fits that case better.
Does the converter handle nested types like Offer inside Product?
Yes — nested objects become nested `<div itemscope>` elements with their own `itemtype`, matching how Microdata expresses structured relationships.
Is my data uploaded anywhere?
No — the conversion happens entirely in your browser. Nothing is sent to a server.
How we compare
| Feature | Online Tool Store | Manual rewriting | Schema markup generators |
|---|---|---|---|
| Converts existing JSON-LD you already have | ✓ | Rewrite by hand, error-prone | Usually builds from scratch, not from existing JSON-LD |
| No install | ✓ | ✓ | ✓ |
For migrating existing JSON-LD into a CMS template that only supports inline markup, this beats rewriting the structured data by hand.
