This Skill handles any task where a spreadsheet file is the primary input or output. ## Core Features & Use Cases - Read and Edit Spreadsheets: Open, inspect, and modify existing .xlsx, .xlsm, .csv, and .tsv files. - Create New Spreadsheets: Build workbooks from scratch or generate them from other data sources. - Format Conversion & Cleanup: Convert between tabular file formats and restructure messy data into proper spreadsheets. - Use Case: A user provides a messy CSV export from a legacy system and asks for a clean, well-structured Excel workbook with proper headers and data types. ## Quick Start Ask the assistant to open the attached sales-data.csv file and convert it into a formatted Excel workbook with cleaned columns.
