将自定义类转换为Excel

使用Aspose.Cells for Python via .NET API，您可以将自定义类转换为Excel、OpenOffice、Pdf、Json及多种不同格式。

将自定义类转换为Excel

有时候，我们拥有一组类，如果想把类信息导入到Excel文件中，一个方便的解决方案是使用Python的反射机制，包含类数据和成员变量的名称，而无需预先知道类的具体元数据。 以下是一段示例代码，演示如何使用Aspose.Cells for Python via .NET将用户定义类列表中的数据导入Excel文件： 文件ImportCustomObject.py定义了要导入的类信息，并使用Python的反射机制，将类数据和成员变量名包含到特定单元格范围内。

from datetime import date, datetime
import aspose.cells as ac

class MyClass:
    def __init__(self, Name, Age, Is_Student, Date, DateTime, Height):
        self.Name = Name
        self.Age = Age
        self.Is_Student = Is_Student
        self.Date = Date
        self.DateTime = DateTime
        self.Height = Height

def import_custom_object(people, cells, row, column, import_options):
    # If a header needs to be displayed, write the header (attribute names)
    if import_options.is_field_name_shown:
        header = vars(people[0]).keys()
        for col_index, attr_name in enumerate(header):
            cells.get(row, column + col_index).put_value(attr_name)
        row += 1

    # Write the attribute values of the object
    for obj in people:
        for col_index, (attr_name, attr_value) in enumerate(vars(obj).items()):
            cell = cells.get(row, column + col_index)
            if isinstance(attr_value, (int, float, str, bool)):
                cell.put_value(attr_value)
            elif isinstance(attr_value, (date, datetime)):
                cell.put_value(attr_value)
                style = cell.get_style()
                if isinstance(attr_value, datetime):
                    style.custom = "yyyy-MM-dd HH:mm:ss"
                elif isinstance(attr_value, date):
                    style.number = 14  # Excel Date Format
                cell.set_style(style)
            else:
                cell.put_value(str(attr_value))
        row += 1

文件TestImportCustomObject.py演示了一个简单示例。用户可以参考此示例或稍作修改以导入自己的数据。

from datetime import date, datetime
import aspose.cells as ac
from ImportCustomObject import MyClass, import_custom_object

people = [
    MyClass("Bob", 30, True, date(2024, 3, 9), datetime.now(), 112.0),
    MyClass("Lucy", 25, False, date(2024, 3, 10), datetime.now(), 111.1),
    MyClass("Tom", 45, True, date(2024, 3, 11), datetime.now(), 110.8),
]

workbook = ac.Workbook()
worksheet = workbook.worksheets[0]
cells = worksheet.cells
import_options = ac.ImportTableOptions()
# Display the table header or not
import_options.is_field_name_shown = True
start_row = 4
start_column = 1
import_custom_object(people, cells, start_row, start_column, import_options)
workbook.save("import_custom_object.xlsx")
