## Why create_excel_from_json is rated Medium

This tool creates new Excel files from JSON input, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money.

From the tool's own definition: "Tool name 'create_excel_from_json' and description '从 JSON 数据创建 Excel 文件' (Create Excel file from JSON data) indicates file creation/generation."
