3. Adjust indentation or sort object keys if needed.

When this helps

Use this JSON formatter before debugging API responses, editing configuration files, or checking structured data snippets. The validator reports syntax errors with location details when the browser can detect them.

If you are preparing publishing content, the Markdown to HTML Converter can help turn formatted notes into clean HTML output.
