Excel Creation via Shell Heredoc Fallback

Overview

When creating Excel files with openpyxl, execute_code_sandbox may fail due to sandbox restrictions, missing dependencies, or permission issues. This skill provides a reliable fallback: execute Python code via run_shell using an inline heredoc script. This approach often succeeds where the sandbox fails and supports full openpyxl features including styling, formulas, and formatting.

When to Use This Skill

• execute_code_sandbox fails when importing or using openpyxl

• You need to create Excel files with advanced formatting (styles, colors, merged cells, formulas)
