        sAlert("worksheet " + formulario.name);
        var worksheet = wb.Sheets[formulario];        
        //var worksheet = workbook.Sheets[workbook.SheetNames['Formulario']];
        sAlert("worksheet " + worksheet.name);
        // Agora você pode trabalhar com os dados da planilha
        var jsonData = XLSX.utils.sheet_to_json(worksheet, { header: 1 });
        sAlert(jsonData);
        //console.log(jsonData);

        // Exemplo de como acessar uma célula específica
        var cellValue = worksheet['A1'].v;
        sAlert(cellValue);
        //console.log(cellValue);
    };

    sAlert("readAsArrayBuffer " + file.name);
    reader.readAsArrayBuffer(file);
    
    //sAlert($(this)[0].files);
};

我想包括XLSX.read库，但我不知道如何，有人可以帮助我吗？
