Information

What is a JSON5 Validator?

A JSON5 Validator checks JSON5 (JSON for Humans) syntax and format. JSON5 is an extension of JSON that allows additional features like comments, trailing commas, and more flexible syntax to make configuration files more human-readable.

Key features of our JSON5 Validator:

  • Validates JSON5 syntax including comments (// and )
  • Supports trailing commas in objects and arrays
  • Allows unquoted property names and single-quoted strings
  • Validates hexadecimal and infinity numeric values
  • Checks for proper bracket and brace matching
  • Provides detailed error messages with line numbers
  • Supports multiline strings and escape sequences
  • Validates object and array structure integrity

This tool is perfect for developers working with configuration files, data interchange, and modern JavaScript projects that use JSON5 for better readability and maintainability.
