# Prompt Cells

> Prompt cells are used to prompt and instruct Julius on what to do (structure the data, process user inputs, create charts/visualizations, etc.)

<div style={{ display: "flex", justifyContent: "center" }}>

Using a prompt cell is similar to using the chat interface. You can use both natural language and technical language when prompting, depending on your preference or use case.

This prompt cell tells Julius to validate that the data is consistent:

</div>

Once you run the prompt cell, Julius will write and execute the python code to fulfill your prompt.
