API Overview

Aspose.Cells FOSS API Reference

Properties

Aspose.Cells FOSS is an open-source Python library for creating, reading, and modifying spreadsheet files without requiring Microsoft Excel. It supports XLSX and CSV formats for input, and adds Markdown export via save_as_markdown(). 该库的结构围绕一个 Workbook 根对象，管理工作表、样式、图表和 I/O。.

核心入口点是 Workbook.每个 Workbook 包含一个或多个 Worksheet 对象，可通过 wb.worksheets[index]. 单元格可通过 Cells 集合使用 A1 表示法或零基行/列索引进行访问。.

from aspose.cells_foss import Workbook

wb = Workbook()
ws = wb.worksheets[0]
ws.cells["A1"].value = "Revenue"
ws.cells["B2"].value = 42
wb.save("output.xlsx")

Workbook 和 Worksheet

Properties Workbook 类是所有电子表格操作的根对象。它负责文件加载、保存以及对工作表和文档属性的访问。.

from aspose.cells_foss import Workbook

wb = Workbook()                      # new workbook
wb = Workbook("input.xlsx")          # open existing file
wb = Workbook("protected.xlsx", password="secret")  # open encrypted file

ws = wb.worksheets[0]                # first worksheet (0-based)
ws = wb.add_worksheet("Sheet2")      # add a named worksheet

ws.cells["A1"].put_value("Hello")    # write by A1 reference
ws.cells["A1"].value                 # read value (property, no parentheses)
ws.cells["A2"].formula = "=SUM(B1:B5)"

wb.save("output.xlsx")               # save as XLSX
wb.save("output.csv")                # auto-detects format from extension
wb.save_as_markdown("output.md")     # export as Markdown table
wb.save("output.xlsx", password="secret")  # save with AES encryption

Properties

使用以下方式向工作表添加图表 add_* 方法 ws.charts. 每个方法接受四个位置参数：: top_row, left_col, bottom_row, right_col. 通过索引访问图表以设置其标题和数据系列。.

from aspose.cells_foss import Workbook

wb = Workbook()
ws = wb.worksheets[0]
chart_idx = ws.charts.add_line(upper_left_row=0, upper_left_col=4,
                                lower_right_row=20, lower_right_col=12)
chart = ws.charts[chart_idx]
chart.title = "Monthly Sales"
chart.n_series.add("B2:B7", category_data="A2:A7", name="Sales")

# Other add methods: add_bar, add_pie, add_area, add_scatter,
# add_waterfall, add_combo, add_stock, add_surface, add_radar,
# add_treemap, add_sunburst, add_histogram, add_funnel,
# add_box_whisker, add_map

Properties

使用以下方式向工作表添加绘图形状和文本框 ws.shapes.

from aspose.cells_foss import Workbook
from aspose.cells_foss import MsoDrawingType, TextAlignmentType, TextAnchorType

wb = Workbook()
ws = wb.worksheets[0]

shape = ws.shapes.add(MsoDrawingType.ROUNDED_RECTANGLE, 1, 1, 5, 5)
shape.text = "Hello"
shape.fill.fore_color = "90EE90"
shape.font.bold = True
shape.text_horizontal_alignment = TextAlignmentType.CENTER
shape.text_vertical_alignment = TextAnchorType.MIDDLE

textbox = ws.shapes.add_text_box(7, 1, 11, 8)
textbox.text = "Notes"

单元格值和样式

使用以下方式读取和写入单元格值 .value 属性。通过访问来修改格式 cell.style 直接。.

from aspose.cells_foss import Workbook

workbook = Workbook()
worksheet = workbook.worksheets[0]

# Write values
worksheet.cells["A1"].value = "Hello"
worksheet.cells["B1"].value = "World"
worksheet.cells["A2"].value = 42
worksheet.cells["B2"].value = 3.14

# Read a value
value = worksheet.cells["A1"].value
print(f"Cell A1 contains: {value}")

# Apply a style via the cell's style property
cell = worksheet.cells["A1"]
cell.style.font.bold = True
cell.style.font.size = 14
cell.style.font.color = "FF0000"          # RRGGBB hex, no # prefix
cell.style.set_horizontal_alignment("center")
cell.style.set_number_format("#,##0.00")
cell.style.set_border("bottom", line_style="thin")

workbook.save("output.xlsx")

注意：在设置时 font.color,，使用不带前缀的十六进制字符串 # 前缀（例如，., "FF0000" 用于红色)。.

数据验证

使用以下方式向单元格范围添加下拉列表或其他验证规则 ws.data_validations.

from aspose.cells_foss import Workbook, DataValidationType

workbook = Workbook()
worksheet = workbook.worksheets[0]

validation = worksheet.data_validations.add("A1:A10")
validation.type = DataValidationType.LIST
validation.formula1 = '"Option1,Option2,Option3"'

workbook.save("validation.xlsx")

Properties

保存或打开受密码保护的工作簿：:

from aspose.cells_foss import Workbook

workbook = Workbook()
worksheet = workbook.worksheets[0]
worksheet.cells["A1"].value = "Confidential Data"

# Save with password protection
workbook.save("protected.xlsx", password="mypassword")

# Open a password-protected file
workbook2 = Workbook("protected.xlsx", password="mypassword")

公共 API

Properties Cells 类提供使用 A1 样式表示法（例如，）访问单个单元格., "A1") 或基于 1 的行/列元组索引。该 Cell 类表示单个单元格并公开 value, formula,，以及 style 作为可读写属性。支持通过以下方式合并和取消合并单元格 merge() 以及 unmerge() 方法在 Cells.

from aspose.cells_foss import Workbook

workbook = Workbook()
worksheet = workbook.worksheets[0]
worksheet.cells["A1"].value = "Hello"
worksheet.cells["B1"].value = "World"    # A1 notation preferred
workbook.save("output.xlsx")
