How to use JSON to Swift Codable Struct Generator

  1. Paste or edit the json object.
  2. Select generate swift struct to process the input locally in your browser.
  3. Review the output, then copy it or download the converted file.

Convert JSON to Swift Codable Struct without losing useful fields

Creates a Codable struct for a representative JSON object. Values use JSONValue where shapes are mixed or nested so the generated model does not discard input data.

Check the output before importing it

The converter reports invalid or unsupported input rather than guessing silently. Review the generated values in the destination application, especially date formats, nested data and identifiers that may have special meaning there.

Example input

{"first_name":"Ada","age":36,"active":true}

Is my input stored?

No. This conversion runs in your browser and your input is not uploaded.

Is input uploaded?

Processing takes place in your browser. This tool does not send your input or selected files to a conversion API.
