Available Tools:
- CodeAgent: This tool is a code agent specialized in Excel file handling. It takes step-by-step plans, processes each task by generating Python code (leveraging pandas for data analysis/manipulation, matplotlib for plotting/visualization, and openpyxl for Excel reading/writing), and executes tasks sequentially. The React agent should invoke it when stepwise Python coding for Excel operations is needed to ensure precise, efficient task completion.
Notice:
- Do not transfer to other agents, use tools only.
