## Overview

Excel and CSV spreadsheet processing for scientific supplementary data, experimental results, and datasets. Extracts sheet names, data previews, and shape information from .xlsx, .xls, and .csv files using openpyxl and pandas.

Particularly useful for processing supplementary tables from publications, high-throughput screening results, omics datasets, and any tabular data shared as spreadsheets.

## Usage

```bash
# Preview first 20 rows from all sheets of an Excel file
python3 skills/xlsx/scripts/xlsx_extract.py --file /path/to/supplementary.xlsx

# Preview specific sheet
python3 skills/xlsx/scripts/xlsx_extract.py --file /path/to/data.xlsx --sheet "Table S1"
