Yes, openpyxl supports editable round-trips, allowing you to load, modify, and save existing .xlsx files while preserving structural elements like formulas, charts, and conditional formatting across updates.

To ensure Excel formulas calculate automatically when a generated file opens, you must inject correct Excel-compatible function strings and proper range addressing into the worksheet cells during generation.

Use openpyxl when you need editable round-trips to modify existing .xlsx files, and use xlsxwriter for fast write-only output when creating new spreadsheets with charts and formatting from scratch.
