To automate Excel workbooks and preserve formulas, use openpyxl to create or edit spreadsheets and run LibreOffice via recalc.py to recalculate formulas. This ensures formulas and formatting are consistently maintained during automated workflows.

Yes, you can use openpyxl to modify existing XLSX files without losing formulas. The Skill reads and edits spreadsheets while preserving formulas and structure, then uses LibreOffice recalculation to verify updated results.

Yes, LibreOffice is required to recalculate formulas in automated Excel workflows. The Skill uses a recalc.py utility that calls LibreOffice to compute formula results after openpyxl manipulates the workbook file.

Supported spreadsheet formats for automated data analysis and visualization include XLSX, XLSM, CSV, and TSV. The Skill uses pandas and openpyxl to handle file manipulation, data analysis, and chart generation across these formats.

The best way to add and verify a formula is to use openpyxl to create the workbook and insert formulas like =SUM(B2:B10), save the file, then run python recalc.py example.xlsx to recalculate and verify the computed results.

This Excel automation approach supports multi-sheet data analysis workflows by reading and analyzing data across sheets with preserved formulas. It handles formatting, summaries, and visualization for comprehensive workbook processing.
