Conversion rulesYour JSON value is rendered as a literal in the target language: objects become keyed structures, arrays become lists, and quotes, backslashes and interpolation markers inside strings are escaped for you. This page does not infer types or generate class definitions.Runs locally — no fixed size limit (bounded by browser memory)

Data, Not Class Definitions

This page renders your JSON value as a pasteable Ruby Hash — it does not generate classes.

Hash Rocket Syntax

String keys use hash rockets and are left exactly as they are in your JSON — they aren't silently turned into symbols.

Interpolation Escaped

Interpolation markers inside string values are escaped, so nothing in your data gets evaluated as code at runtime.

Community-Standard Indentation

Two-space indentation per Ruby convention, with nested hashes and arrays clearly stepped.

Runs Locally — No Upload

Conversion runs in your browser; data is never uploaded.
