Excel workbooks with formulas that stay editable.
Creates and updates Excel workbooks with formulas, formatting, and formula-error checks.
When to use it
Use when asked to create, edit, or analyze an .xlsx file.
Give it a spreadsheet task and any existing workbook; it creates, edits, or analyzes an Excel file.
What you provide
The bundled formula-recalculation script runs with Python 3.
LibreOffice must already be installed for formula recalculation; the instructions assume it is available.
The recalculation script imports openpyxl to inspect workbook values and formulas.
