JSON-LD Formatter

Last updated:

Beautify, minify, and validate JSON-LD structured data in one place. Catch syntax errors before they break your rich results, then copy clean markup or a ready-to-paste script tag for your pages.

Runs in your browser. Your structured data is never uploaded.

How the JSON-LD Formatter Works

  1. Paste markup, drop in JSON-LD copied from your page or a generator.
  2. Beautify or minify, format with your chosen indentation or compress to one line.
  3. Read the status, valid JSON is confirmed, or the exact error position is shown.
  4. Copy and paste, take the clean output, optionally wrapped in a script tag, into your site.

Why Clean JSON-LD Matters

  • Rich results, a single syntax error can disqualify a page from rich snippets.
  • Easier maintenance, readable markup is faster to audit and update over time.
  • AI citations, valid structured data helps answer engines understand and cite your content.
  • Fewer regressions, validating before you publish stops broken schema from shipping.

After formatting, confirm rules with our schema markup validator. For a full structured-data implementation across your site, see our GEO services.

JSON-LD Core Fields Reference

A few special keys give JSON-LD its structure. Place the markup inside a <script type="application/ld+json"> tag in the head or body, and make sure it is valid JSON, since a single syntax error stops parsers from reading any of it.

Field Purpose Example
@contextDeclares the vocabulary so parsers know each term comes from schema.org."@context": "https://schema.org"
@typeNames the kind of entity being described."@type": "Organization"
@idAn optional stable URL that uniquely identifies the entity so it can be referenced across pages."@id": "https://example.com/#org"

Placement: the <script type="application/ld+json"> block can sit in the <head> or <body>. Its contents must be valid JSON, with double-quoted keys and no trailing commas, or search engines will skip the whole block.

JSON-LD Formatter: FAQ

What does Beautify change?
Beautify parses the input as JSON and serializes it with the selected two-space, four-space, or tab indentation. Property order is generally retained by JavaScript serialization, but insignificant whitespace and some numeric representations can change.
What does Minify change?
Minify parses the same data and writes it without indentation or line breaks. It reduces source characters but does not change the schema meaning, validate claims, or improve rich-result eligibility by itself.
What syntax errors can it catch?
Because it uses JSON.parse, it catches invalid JSON such as trailing commas, single-quoted keys, comments, and mismatched brackets. Paste only the JSON payload, not an existing script element, or parsing will fail.
What JSON-LD structure checks are included?
For a top-level object or each object in a top-level array, the tool warns when @context or @type is missing. An object containing @graph is exempt from those warnings. These are lightweight checks, not full JSON-LD expansion or schema validation.
Does a green result mean Google can show a rich result?
No. It means the JSON parsed and the lightweight top-level checks passed. It does not verify schema.org properties, entity relationships, page-content consistency, Google's feature requirements, or whether the page is crawlable.
How does the script-tag option work?
The checkbox affects copying only. It wraps the current output, or the original input if no formatted output exists, in a script element with type application/ld+json. It does not add that block to your website.
Can the formatter handle arrays and @graph?
Yes, valid JSON arrays can be formatted, and @graph objects parse normally. Review entity @id references and graph structure with a dedicated structured-data validator because this tool does not resolve or cross-check them.
Is the JSON-LD I paste sent to a server?
No. Parsing, warnings, formatting, minification, and copying happen in your browser. This tool does not submit the JSON-LD content to a Web Aloha endpoint.
