Frequently Asked Questions

Does it generate Codable conformance?
Yes. All generated structs conform to the Codable protocol, enabling easy JSON encoding and decoding in Swift.
Are CodingKeys generated automatically?
Yes. When JSON keys differ from Swift property names (e.g., snake_case to camelCase), CodingKeys are automatically generated.
Does it handle nested objects?
Yes. Nested JSON objects are converted to separate Swift structs with proper type references.

About JSON to Swift

Most online tools for this task bury what you need behind ads and forms. JSON to Swift takes the opposite approach: load the page, do the job, leave. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.

When you'd reach for JSON to Swift

  • You're hitting the daily limit of a paid SaaS and need a backup option for a single quick job.

    Marketers and ops people whose primary tool is metered.

    Stay productive without burning credits.

  • You need to handle a one-off task right before a meeting and don't have time to install anything.

    Anyone working remotely on a borrowed or restricted machine.

    Open the page, get the result, paste it into your doc — under a minute.

  • You're cleaning up a folder of files that accumulated over a project and need to standardize them.

    Designers, writers, and developers wrapping up deliverables.

    Drop each file in, copy the output, move on.

  • You're on a public or shared machine and don't want to leave traces of what you're working on.

    Nothing is uploaded, nothing persists if you're not signed in.
