What problem does it solve?
This Skill automates the creation, editing, formatting, cleaning, and validation of spreadsheet workbooks. It helps users manage Excel files (.xlsx, .xlsm) and related tabular formats (.csv, .tsv) by turning manual spreadsheet work into reliable, repeatable automation.
Core Features & Use Cases
- Automated workbook creation from data sources and templates.
- Edit, format, and compute: apply formulas, restructure data, fix messy data, and ensure consistency across sheets.
- Interformat conversion and validation: convert between CSV/TSV and Excel formats and verify content integrity; recalc formulas to prevent errors.
- Real-world scenario: consolidate a set of CSV invoices into a single output.xlsx with per-row totals and consistent formatting.
Quick Start
Create a new workbook from a CSV input, apply a simple sum formula to a column, and save the result as output.xlsx.
