+# openpyxl - ler e alterar dados de uma planilha
+# Com essa biblioteca será possível ler e escrever dados em células
+# específicas, formatar células, inserir gráficos,
+# criar fórmulas, adicionar imagens e outros elementos gráficos às suas
+# planilhas. Ela é útil para automatizar tarefas envolvendo planilhas do
+# Excel, como a criação de relatórios e análise de dados e/ou facilitando a
+# manipulação de grandes quantidades de informações.
+# Instalação necessária: pip install openpyxl
+# Documentação: https://openpyxl.readthedocs.io/en/stable/
