How to use JS Object to JSON

Paste a JavaScript object literal, and the tool converts it into valid JSON with proper key quoting and escaping.

Frequently asked questions

Why convert JavaScript to JSON?

JSON is required for APIs, data storage, and data interchange. Converting ensures your data is in the correct format with proper escaping.

What changes are made during conversion?

Single quotes become double quotes, unquoted keys get quotes, comments are removed, and trailing commas are removed to create valid JSON.

Can it handle functions in objects?

No, JSON doesn't support functions. Only data types (strings, numbers, booleans, arrays, objects, null) are converted. Functions are stripped.
