What is JSON-LD Formatter?
The JSON-LD Formatter reformats pasted JSON-LD and checks two basic structural requirements: valid JSON syntax plus the presence of `@context` and `@type`. It is useful when you want cleaner, easier-to-read schema markup before implementation or debugging.
How does JSON-LD Formatter work?
This tool is a formatter and lightweight checker for JSON-LD snippets. You paste existing markup, choose an indentation level, and the tool parses the JSON, reformats it, and reports whether the snippet includes `@context` and `@type`.
Key Features
- Formats pasted JSON-LD with adjustable indentation from 0 to 8 spaces
- Checks whether the input is valid JSON syntax
- Checks for the presence of @context and @type
- Includes presets for Article, Product, FAQ, and Organization examples
- Returns readable formatted output in the browser
- Shows basic validation feedback when JSON is malformed or key fields are missing
- Lets you copy the formatted result or download it as a JSON file
Common Use Cases
Schema cleanup before deployment
Reformat messy JSON-LD so it is easier to review and implement.
Quick syntax checks
Confirm whether a JSON-LD snippet parses correctly before testing it elsewhere.
Basic required-field review
Check whether a snippet includes the two core fields this tool looks for: @context and @type.
Developer or CMS handoff
Produce cleaner JSON-LD output for teammates who need readable schema markup.
Preset-based schema examples
Start from a sample schema block, then adapt it for your own implementation.
How to Use This Tool
Paste your JSON-LD
Add the schema markup you want to reformat or check.
Choose the indentation level
Set the spacing level you want the formatted output to use.
Run format and validation
Let the tool parse the JSON, reformat it, and check for @context and @type.
Review the output and messages
Use the validation result to catch malformed JSON or missing required top-level fields.
Copy or download the result
Use the formatted JSON-LD in your debugging or implementation workflow.
Pro Tips
- 1
This tool performs basic structural checks only, so it does not replace a full rich-results or schema eligibility validator.
- 2
If the input is invalid JSON, fix the syntax first before worrying about higher-level schema issues.
- 3
Use the presets when you need a clean starting point for common schema types.
- 4
Formatted output improves readability, but it does not change what the markup means.
- 5
After cleanup here, validate the final page markup externally if you need deeper search-feature checks.
