How to use JSON to Pike

  1. Paste a representative JSON sample, ideally one with all the optional fields filled in.
  2. Set the name of the root type, and decide whether you want helper code as well or types only.
  3. Copy the generated Pike code into your project.

About JSON to Pike

Writing model classes by hand for a big JSON payload is dull, and it is where typos creep in. Paste a sample here and the generator works out the structure: which fields exist, which are objects, which are arrays and what type each value has. The output is classes with encode_json and decode helpers using the Standards.JSON module.

Pike is a niche language, so the output is meant as a starting point you adjust to your project. Everything runs in your browser, so your sample data stays on your machine.

Using the generated code

Call Root(Standards.JSON.decode(text)).

Optional values are typed as mixed or as a union with zero.

Frequently asked questions

What does the generated Pike code depend on?

The output is classes with encode_json and decode helpers using the Standards.JSON module.

How do I parse JSON with the result?

Call Root(Standards.JSON.decode(text)).

How are optional and missing fields handled?

Optional values are typed as mixed or as a union with zero.

Does the generator look at more than one record?

It only knows what is in your sample. If a field is missing from your example, it will not appear in the types, and if a value is null in your example, its type is unknown. Paste an example in which as many fields as possible are filled in, or paste an array with several different records.

Is my JSON sent to a server?

No. The generator is downloaded to your browser the first time you use it, about 1 MB, and everything runs locally.
