The JSON Formatter / Minifier helps developers, SEO teams, and content managers validate structured data and API snippets quickly. Paste JSON, format it for readability, or minify it for compact storage.
Because the parser runs in your browser, private snippets and draft structured data are not uploaded to a third-party service.
Format or Minify JSON
How to Use
Paste JSON
Add a JSON object, array, schema snippet, or API response into the input area.
Format or Minify
Choose Format for readable indentation or Minify for compact single-line output.
Copy Output
Copy the valid result into your code, CMS field, or documentation.
Why Use This Tool?
Validates syntax: Find broken commas, brackets, and quotes before publishing.
Improves readability: Pretty-print JSON so nested data is easy to inspect.
Minifies safely: Remove whitespace after validation for compact output.
Practical Example
An SEO specialist can paste FAQ schema JSON-LD, format it to inspect each question, then minify it before placing it on a page.
