Code Formatters

Beautify and validate JSON, SQL, JavaScript, and TypeScript in the browser. Paste or load a snippet, run the formatter, and get indented, readable output with syntax checks that help catch missing commas, brackets, and other structural mistakes before you paste the code back into an editor or query tool.

When to use a formatter

Use these tools to tidy minified or messy snippets and to confirm that a payload or query is structurally valid. They format and check syntax—they do not execute code or redesign your application architecture.

Limits

Formatters follow common language rules; dialect-specific SQL or unusual JS/TS constructs may need a follow-up pass in your IDE. Do not paste secrets into shared machines.
