# JSON Knowledge Base

> Learn how to use local JSON files in your knowledge base.

The **JSONKnowledgeBase** reads **local JSON** files, converts them into vector embeddings and loads them to a vector database.

## Usage

<Note>
  We are using a local PgVector database for this example. [Make sure it's running](https://docs-v1.agno.com/vectordb/pgvector)
</Note>

```python knowledge_base.py theme={null}
from agno.knowledge.json import JSONKnowledgeBase
from agno.vectordb.pgvector import PgVector

knowledge_base = JSONKnowledgeBase(
    path="data/json",
    # Table name: ai.json_documents
    vector_db=PgVector(
        table_name="json_documents",
        db_url="postgresql+psycopg://ai:ai@localhost:5532/ai",
    ),
)
```

Then use the `knowledge_base` with an `Agent`:

```python agent.py theme={null}
from agno.agent import Agent
from knowledge_base import knowledge_base

agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)
agent.knowledge.load(recreate=False)

agent.print_response("Ask me about something from the knowledge base")
```

#### JSONKnowledgeBase also supports async loading.

```shell theme={null}
pip install qdrant-client
```

We are using a local Qdrant database for this example. [Make sure it's running](https://docs-v1.agno.com/vectordb/qdrant)

```python async_knowledge_base.py theme={null}
import asyncio
from pathlib import Path

from agno.agent import Agent
from agno.knowledge.json import JSONKnowledgeBase
from agno.vectordb.qdrant import Qdrant

COLLECTION_NAME = "json-reader"

vector_db = Qdrant(collection=COLLECTION_NAME, url="http://localhost:6333")

knowledge_base = JSONKnowledgeBase(
    path=Path("tmp/docs"),
    vector_db=vector_db,
    num_documents=5,  # Number of documents to return on search
)

# Initialize the Agent with the knowledge_base
agent = Agent(
    knowledge=knowledge_base,
    search_knowledge=True,
)

if __name__ == "__main__":
    # Comment out after first run
    asyncio.run(knowledge_base.aload(recreate=False))

    # Create and use the agent
    asyncio.run(
        agent.aprint_response(
            "Ask anything from the json knowledge base", markdown=True
        )
    )
```

## Params

| Parameter | Type               | Default        | Description                                                                              |
| --------- | ------------------ | -------------- | ---------------------------------------------------------------------------------------- |
| `path`    | `Union[str, Path]` | -              | Path to `JSON` files.<br />Can point to a single JSON file or a directory of JSON files. |
| `reader`  | `JSONReader`       | `JSONReader()` | A `JSONReader` that converts the `JSON` files into `Documents` for the vector database.  |

`JSONKnowledgeBase` is a subclass of the [AgentKnowledge](/reference/knowledge/base) class and has access to the same params.
