# XLSX creation, editing, and analysis

## Overview

A user may ask you to create, edit, or analyze the contents of an .xlsx file. You have different tools and workflows available for different tasks.

Must output excel files.

## Important Requirements

**Python 3 and openpyxl Required for Excel Generation**: You can assume Python 3 as the runtime environment. The `openpyxl` library is required as the primary tool for creating Excel files, managing styles, and writing formulas.

**pandas Utilized for Data Processing**: You can utilize `pandas` for efficient data manipulation and processing tasks. The processed data is subsequently exported to the final Excel file through `openpyxl`.

**LibreOffice Required for Formula Recalculation**: You can utilize `recalc.py` for formula check. You can assume LibreOffice is installed for recalculating formula values using the `recalc.py` script. The script automatically configures LibreOffice on first run.
