SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables end-to-end spreadsheet automation for when a spreadsheet is the primary input or output. It addresses tasks such as opening, reading, editing, or fixing existing .xlsx, .xlsm, .csv, or .tsv files; creating new spreadsheets from scratch or from other data sources; analyzing data and exporting results as Excel workbooks with charts; converting between tabular formats (CSV/JSON/PDF → XLSX or vice versa); and cleaning, merging, pivoting, or transforming tabular data. It is triggered especially when a user references a spreadsheet by name or path or mentions terms like make a table/report/model, Excel/CSV, 数据分析/报表/汇总, or data visualization inside a spreadsheet.

Quick Start

Open a target spreadsheet, apply requested transformations, and save a polished workbook with consistent styling.

Can I convert CSV and PDF files into formatted XLSX workbooks?

Yes, you can convert CSV and PDF files into formatted XLSX workbooks. The process reads various tabular formats, applies predefined styling guidelines, and exports a polished Excel workbook with consistent formatting and structural integrity.

What is the best way to pivot and clean spreadsheet data without formula errors?

The best way to pivot and clean spreadsheet data without formula errors is using deterministic automation that enforces safe defaults. It validates deliverables before delivery to ensure zero formula errors and maintains structural integrity throughout the transformation.

Does spreadsheet automation support opening and editing XLSM files?

Yes, spreadsheet automation supports opening and editing XLSM files. It can safely open, inspect, modify, and format .xlsx, .xlsm, .csv, and .tsv files while preserving existing formats and enforcing safe defaults during modifications.

How do I generate Excel workbooks with charts from raw data?

You generate Excel workbooks with charts from raw data by analyzing the input, performing necessary data transformations, and exporting the results. The output is a polished Excel workbook containing visualizations and consistently styled data tables.

Why does my automated spreadsheet formatting break existing styles?

Automated spreadsheet formatting breaks existing styles when tools overwrite native formats. This automation prevents that by preserving existing formats and applying styling via design tokens, enforcing safe defaults to maintain structural integrity and consistent formatting.
