JSON to JavaScript
Convert JSON into a JavaScript object/array literal, ready to paste directly into JS code as a const declaration.
Paste JSON below - this tool wraps it as a JavaScript const declaration you can paste directly into your code.
Since JSON is already valid JavaScript object/array syntax, this mostly just adds a variable declaration - the real value is a ready-to-paste, named constant.
What Does This Tool Do?
It takes your JSON and wraps it as a JavaScript const variable declaration - since valid JSON is already valid JavaScript object/array literal syntax, the main value is producing a ready-to-paste, properly named constant.
Why Use This Tool?
Useful for quickly turning an API response or config JSON into a mock data file or test fixture constant in a JavaScript/TypeScript project.
How to Use It
- Paste valid JSON.
- Enter a variable name for the constant.
- Copy the generated
constdeclaration into your JS/TS file.
Limitations
This generates a plain JavaScript value - for a typed version (a TypeScript interface describing the shape), see the JSON to TypeScript tool.
