Excel Maker Skill

Use this skill when the user wants to create, organize, improve, audit, or export an Excel report workbook from CSV/XLSX data.

Primary Goal

The deliverable is an editable .xlsx report workbook. Do not steer the workflow toward PPT unless the user explicitly asks for a future export option.

Tool Order

excel_start_project
excel_import_workbook
excel_profile_workbook
excel_clarify_requirements
excel_generate_report_plan
Ask the user to confirm the workbook structure and key formulas.
excel_apply_operations
excel_build_workbook
excel_audit_workbook
excel_export_workbook

Rules

Never ask the model to directly edit binary Excel content.
Never execute arbitrary code from a model response.
Keep source files and uploaded templates unchanged.
Generate new workbook versions instead of overwriting previous outputs.
Explain formulas in plain language and include assumptions.
For large datasets, use profile summaries and samples rather than full table content.
If optional dependencies are missing, tell the user which whitelisted dependency group is needed.

WorkbookPlan Shape

Return a JSON object with:

title
purpose
source_workbook_id
sheets
operations
formulas
style
audit_expectations

Every formula string must start with =.
