XLSX

Spreadsheet automation with formulas involves programmatically creating or modifying .xlsx files to insert calculated values, apply functions, and update cells without manual entry. This Skill automates formula insertion, data manipulation, and report generation in Excel workbooks, eliminating repetitive tasks and formula errors while preserving existing formatting and formulas.

Yes, this Skill reads and analyzes data from .xlsx, .xlsm, .csv, and .tsv files programmatically. It supports extracting specific cell values, analyzing columns, and performing calculations, enabling automated data workflows without manual spreadsheet operations.

Report generation from raw data involves reading source files, calculating aggregates, applying formatting, and structuring results into new sheets or workbooks. This Skill automates this end-to-end process, creating formatted reports with formulas, color coding, and number formatting from raw .xlsx or .csv data.

Updating workbooks safely requires modifying only target cells while preserving existing formulas and formatting. This Skill handles structured updates to .xlsx and .xlsm files, ensuring formulas recalculate automatically and formatting remains consistent across edits.

This Skill uses openpyxl for programmatic .xlsx manipulation and supports LibreOffice-based recalculation via recalc.py, ensuring compatibility across platforms. It works with standard .xlsx, .xlsm, .csv, and .tsv formats independent of Excel version.

Programmatic automation excels at bulk operations, formula precision, and repetitive tasks but requires upfront setup and works best with structured data. Complex conditional formatting, advanced pivot logic, or highly interactive workflows may be better suited to manual or hybrid approaches.
