# Csv Handler

The method leverages a query string provided by the user to generate a filter condition based on the columns of the
CSV file. This condition is used to extract relevant data from the CSV and return it in a structured format. The filtering
logic is generated by an external LLM (Large Language Model) client, which receives a prompt based on the CSV's structure.

## Example

This method is part of the CsvHandler class, which handles CSV file operations, and is specifically designed to search
through the data in the CSV file based on a user-defined query.

To use OpenAI models, you’ll need to create an OpenAI account and get an API key. For more details refer here.

> Set up a OpenAI API key as an environmental variable and run the following code.

```python theme={null}
 export OPENAI_API_KEY = "**************************"
```

```python csv_handler.py theme={null}
import asyncio

from superagentx_handlers.csv_cli import CsvHandler
from superagentx.llm import LLMClient


async def search(query):
    input_path = "<File_path>"
    llm_config = {'llm_type': 'openai'}
    llm_client = LLMClient(llm_config=llm_config)
    csv_handler = CsvHandler(
        file_path=input_path,
        llm_client=llm_client
    )
    return await csv_handler.search(query)


async def main(query):
    res = await search(query)
    print(res)

if __name__ == '__main__':
    query="who are all Petroleum engineer"
    asyncio.run(main(query))
```
