Câu hỏi thường gặp

JSON5 Validator là gì?

A JSON5 Validator is a tool that checks whether text conforms to the JSON5 specification and reports syntax errors with line and column positions. It accepts JSON5 features that standard JSON rejects, including comments, trailing commas, single-quoted strings, and hexadecimal numbers. Running client-side in the browser, it validates and parses JSON5 input without uploading it to a server.
