# JSON Compatible Encoder { #json-compatible-encoder }

There are some cases where you might need to convert a data type (like a Pydantic model) to something compatible with JSON (like a `dict`, `list`, etc).

For example, if you need to store it in a database.

For that, **FastAPI** provides a `jsonable_encoder()` function.

## Using the `jsonable_encoder` { #using-the-jsonable-encoder }

# JSON Uyumlu Encoder { #json-compatible-encoder }

Bazı durumlarda, bir veri tipini (örneğin bir Pydantic model) JSON ile uyumlu bir şeye (örneğin `dict`, `list` vb.) dönüştürmeniz gerekebilir.

Örneğin, bunu bir veritabanında saklamanız gerekiyorsa.

Bunun için **FastAPI**, `jsonable_encoder()` fonksiyonunu sağlar.
