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
- Paste markup, drop in JSON-LD copied from your page or a generator.
- Beautify or minify, format with your chosen indentation or compress to one line.
- Read the status, valid JSON is confirmed, or the exact error position is shown.
- 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.

JSON-LD Formatter: FAQ
What is JSON-LD?
JSON-LD (JSON for Linking Data) is the format Google recommends for structured data. It places schema.org markup inside a script tag of type application/ld+json, separate from your visible HTML, which makes it easy to add, edit, and validate.
What does this formatter do?
It pretty-prints JSON-LD with clean indentation, can minify it to a single line, and validates the JSON syntax so you catch trailing commas, unquoted keys, and bracket errors before you paste the markup into your site.
Does it validate against schema.org types?
It validates JSON syntax and basic JSON-LD structure, such as the presence of @context and @type. For full schema.org rule checking and rich result eligibility, pair it with our schema markup validator and Google Rich Results Test.
Why is my JSON-LD invalid?
The most common causes are trailing commas, single quotes instead of double quotes, missing quotes around keys, unescaped quotes inside strings, and mismatched brackets. The error message points to the line and position so you can fix it fast.
Can it wrap my markup in a script tag?
Yes. Use the copy as script tag option to get a ready-to-paste block with the application/ld+json type, so you can drop it straight into the head or body of your page.
Will it keep my data private?
Yes. Formatting and validation run entirely in your browser. Your structured data is never uploaded to Web Aloha servers.
Does formatting affect SEO?
Whitespace does not affect how search engines read JSON-LD, but clean formatting makes it far easier to maintain and audit, which reduces the risk of errors that block rich results and AI citations.
Is this JSON-LD formatter free?
Yes. It is free, private, requires no signup, and works on any device.
