What is JSON5 Parser?

JSON5 is a superset of JSON that adds many developer-friendly features to make JSON easier for humans to write and read. This JSON5 parser supports all JSON5 features, including: single-line comments (//) and multi-line comments (/* */), trailing commas, unquoted identifier keys, single-quoted strings, hexadecimal numbers, leading/trailing decimal points, implicit positive sign (+123), Infinity, -Infinity, NaN, and more. The tool converts JSON5 input to standard JSON format for use in systems that do not support JSON5.

When to Use JSON5 Parser

Use when parsing JSON configuration files with comments, converting JSON5 format to standard JSON, validating JSON5 syntax, or processing data containing non-standard JSON features.

How to Use JSON5 Parser

Paste JSON5 data into the input area. Click the "Parse" button, and the tool will automatically convert it to formatted standard JSON output. If there is a syntax error, detailed error information will be displayed.
