About JSON to Elixir Converter
The JSON to Elixir converter generates Elixir `defstruct` definitions with `@type t()` typespecs from a JSON sample. Strings become `:binary`, numbers become `:integer` or `:float`, booleans become `:boolean`, and nested objects become nested struct modules. The output follows Elixir module conventions and is ready to paste into a Phoenix or Ecto project.
Features
- ✓Custom JSON-to-Elixir schema inference engine
- ✓Generates defstruct with field defaults
- ✓@type t() typespecs for all fields
- ✓Nested objects → nested Elixir modules
- ✓Arrays → list(T) type annotations
- ✓Follows Elixir CamelCase module and snake_case field conventions
- ✓Download generated Elixir as a .ex file
- ✓Copy output to clipboard in one click
- ✓Web Worker processing — never blocks the UI
- ✓100% client-side — data never leaves your browser
Common Use Cases
- Scaffolding Elixir struct modules from JSON API responses for Phoenix apps
- Generating Elixir data types from JSON configuration files
- Creating typed Elixir domain models from JSON schemas
- Reverse-engineering JSON to Elixir structs for Ecto integration
Frequently Asked Questions
QIs the output Ecto-compatible?
The output generates plain Elixir structs. Converting to Ecto schemas requires adding use Ecto.Schema and changing defstruct to schema/field macros.
QIs my data sent to a server?
No. All schema generation runs in a Web Worker inside your browser.
