When to Use Each
Use ValidateHTML when:
- You validate more than just JSON (HTML, CSS, XML, meta tags)
- You want a clean, modern interface without ads
- You need JSON formatting and minification in one place
- You want character count and formatting stats
Use JSONLint when:
- You need JSON Schema validation
- You only work with JSON and nothing else
- You already have it bookmarked and it works for you
Our Honest Take
JSONLint has been the go-to JSON validator for years. It does one thing well: validate and format JSON. If that's all you need, it works.
ValidateHTML includes a full JSON validator and formatter, plus 11 other tools. If you regularly check HTML, CSS, meta tags, or Open Graph data alongside JSON, having everything in one place saves time. The interface is also cleaner with no ads covering the editing area.
The one thing JSONLint has that we don't is JSON Schema validation. If you need to validate JSON against a specific schema, JSONLint is the better choice for now.
