Code to JSON
Convert a loosely-formatted object/array literal (unquoted keys, single quotes, trailing commas) into strict, valid JSON.
Paste a JS/PHP-style object or array literal below - this tool normalizes common non-strict syntax into valid JSON.
This handles common non-strict patterns (unquoted keys, single quotes, trailing commas) - it isn't a general-purpose parser for arbitrary executable code.
What Does This Tool Do?
It accepts loosely-formatted, JSON-like data - unquoted object keys, single-quoted strings, trailing commas - and normalizes it into strict, standards-compliant JSON.
Why Use This Tool?
Data copied from JavaScript source code, a config file, or an AI-generated snippet often looks like JSON but isn't strictly valid - this tool fixes the common differences automatically instead of you editing every key and quote by hand.
How to Use It
- Paste your loosely-formatted object/array data.
- Click Convert.
- Copy the resulting strict, valid JSON.
Limitations
This handles common non-strict JSON-like patterns - it is not a general JavaScript/PHP code interpreter, so values that require actual code execution (function calls, variables) won't convert.
