JSON to JavaScript Object
Turn JSON into an idiomatic JS object literal
Runs 100% in your browser — nothing is ever uploaded.
What is JSON to JS?
Paste JSON and get an idiomatic JavaScript object literal: keys lose their quotes when valid identifiers, strings switch to single quotes (or double — your choice), and an optional const declaration makes it paste-ready for your codebase or test fixtures.
How to use JSON to JS
- Paste your JSON into the input box or click “Load sample” to try it.
- Adjust the options in the toolbar if needed (delimiter, table name, format …).
- Click the convert button — the JS object appears instantly in the output pane.
- Copy the result with one click or download it as a file.
ConvertLab FAQ
Is the JSON to JavaScript converter free?
Yes — 100% free, no signup, no limits, no watermarks. Use it as often as you like.
What's the difference from plain JSON?
JS literals allow unquoted identifier keys and single-quoted strings — the style ESLint/Prettier codebases expect — while JSON requires double quotes everywhere.
Is my data uploaded to a server?
No. The conversion runs entirely in your browser with JavaScript — your data never leaves your device, which makes the tool safe even for confidential files.
Are these converters free?
Yes — every ConvertLab tool is 100% free with no signup, no limits and no ad walls.
Is my data uploaded anywhere?
No. All conversions (JSON, CSV, XML, YAML, INI, .env) run entirely in your browser. Nothing ever leaves your device.
Do these tools work offline?
Yes — once the page is loaded, every converter works without an internet connection.
