Reliable Excel Workbook Creation via Shell

When to Use This Pattern

Use this technique when you need to:

• Create complex Excel workbooks with multiple sheets
• Perform multi-step workbook operations (create, populate, format, save)
• Work with XLSX files that read_file cannot handle properly
• Avoid failures from execute_code_sandbox on persistent file operations

Avoid: read_file for XLSX files, execute_code_sandbox for multi-step workbook creation
