# 📃 JSON

To add any json file, use the `JsonLoader`.
Headers are included for each line, so for example if you have a json like `{"age": 18}`, then it will be added as `age: 18`.

## Usage

<CodeGroup>
  ```ts Example theme={null}
  import { RAGApplicationBuilder, JsonLoader } from '@llm-tools/embedjs';
  import { OpenAiEmbeddings } from '@llm-tools/embedjs-openai';
  import { HNSWDb } from '@llm-tools/embedjs-hnswlib';

  const app = await new RAGApplicationBuilder()
  .setModel(SIMPLE_MODELS.OPENAI_GPT4_O)
  .setEmbeddingModel(new OpenAiEmbeddings())
  .setVectorDatabase(new HNSWDb())
  .build();

  app.addLoader(new JsonLoader({ object: {...} }))
  ```
