O Excel tem a capacidade de armazenar e organizar rapidamente grandes quantidades de dados em planilhas ordenadas. Mas é demorado inserir manualmente os dados nas células, um após o outro. Automatizar a criação de arquivos Excel por meio de programação pode nos poupar muito tempo e energia. Este artigo apresenta como gravar dados em planilhas do Excel em Java usando Spire.XLS for Java.
- Escreva valores de texto ou números em células específicas
- Escreva matrizes em uma planilha
- Escreva um DataTable em uma planilha
Instale Spire.XLS for Java
Primeiro, é necessário adicionar o arquivo Spire.Xls.jar como uma dependência em seu programa Java. O arquivo JAR pode ser baixado neste link. Se você usa Maven, pode importar facilmente o arquivo JAR em seu aplicativo adicionando o código a seguir ao arquivo pom.xml do seu projeto.

Escreva valores de texto ou números em células específicas
Uma determinada célula em uma planilha pode ser acessada pelo método Worksheet.get(int row, int column). Em seguida, você pode adicionar um valor de texto ou um valor numérico à célula usando o método IXLSRange.setValue() ou IXLSRange.setNumberValue(). A seguir estão as etapas detalhadas.
- Crie um objeto Pasta de trabalho.
- Obtenha a primeira planilha usando o método Workbook.getWorksheets().get().
- Obtenha uma célula específica usando o método Workhseet.get().
- Adicione um valor de texto ou um valor numérico à célula usando o método IXLSRange.setValue() ou IXLSRange.setNumberValue().
- Salve a pasta de trabalho em um arquivo Excel usando o método Workbook.saveToFile().
- Java
import com.spire.xls.*;
public class WriteToCells {
public static void main(String[] args) {
//Create a Workbook object
Workbook workbook = new Workbook();
//Get the first worksheet
Worksheet worksheet = workbook.getWorksheets().get(0);
//Write data to specific cells
worksheet.get(1,1).setValue("Name");
worksheet.get(1,2).setValue("Age");
worksheet.get(1,3).setValue("Department");
worksheet.get(1,4).setValue("Hiredate");
worksheet.get(2,1).setValue("Hazel");
