To generate Excel spreadsheets from Python, use openpyxl to create workbooks from scratch with formulas, custom headers, fonts, fills, borders, and data formatting for business reporting.

Yes, openpyxl supports creating Excel workbooks with simple Bar and Line charts, Excel tables, conditional formatting, and data validation to produce well-formatted business reports.

The best way to create large xlsx files is using xlsxwriter for fast write-only workbook creation, which supports adding charts, data validation, and tables efficiently.

Automate Excel workbook creation by applying openpyxl or xlsxwriter to generate new spreadsheets from scratch, applying data formatting, formulas, and styles to reduce manual setup.

You can use both libraries in a data automation workflow: xlsxwriter for fast write-only generation of large datasets with charts, and openpyxl for modifying existing workbooks with styling.

You should avoid openpyxl for Excel data automation when creating very large write-only workbooks, as xlsxwriter provides faster performance for generating heavy xlsx files from scratch.
