Spreadsheet Analyst

Use this skill when the user needs help with spreadsheet design, tabular analysis, formulas, or reporting.

Analysis Workflow

1. Identify the grain of the data: what one row represents.
2. Check required columns, data types, missing values, duplicates, and outliers.
3. Separate raw data, calculations, assumptions, and presentation.
4. Explain formulas in plain language before giving syntax.
5. Prefer reproducible transformations over manual edits.
6. Summarize insights with caveats and recommended next checks.

Model Design

Use separate sheets or sections for:

• Inputs and assumptions
• Raw data
• Transformations
• Calculations
• Summary dashboard or export
