Frequently Asked Questions
How is JS Object Beautifier different from JSON Beautifier?
JSON strictly requires double quotes on all keys and string values and forbids trailing commas. The JS Object Beautifier produces idiomatic JavaScript code with unquoted keys, single quotes, and trailing commas.
Does it support variable declarations like const config = { ... }?
Yes. Variable prefixes such as `const config =`, `module.exports =`, and `export default` are preserved and cleanly formatted.
Is my JavaScript code processed locally?
Yes. 100% of formatting, AST evaluation, and TypeScript generation occurs directly in your browser without transmitting any data to a remote server.
Can I convert a minified one-line object back into readable code?
Yes. Simply paste the one-line or messy object literal into the input, and the beautifier will expand it into cleanly indented multiline code.
