JSON Validator

Why Validate JSON?

Invalid JSON causes silent failures in APIs, configuration files, and data pipelines. Our validator checks syntax, pinpoints the exact error location, and provides structural analysis including type, node count, and nesting depth.

Features

  • Syntax validation — detects missing brackets, commas, quotes, and more.
  • Error location — pinpoints the line and column of the first error.
  • Structure analysis — reports type, total nodes, and maximum depth.
  • Instant feedback — validation runs entirely in your browser.
