About

Excel 工具

原则

  • 输入表格只读,输出写入 PROJECT_ROOT
  • 普通结果汇总优先 CSV。
  • 题目指定 XLSX、需保留公式、多工作表或模板结构时才使用 XLSX。
  • 不覆盖题目原始附件和 Skill 文件。

读取与写入

import pandas as pd

# 第一行就是数据时必须显式使用 header=None。
data = pd.read_excel("data/input.xlsx", sheet_name=0, header=None)
assert len(data) == 7470, f"行数异常: {len(data)}"
result = pd.DataFrame({"方案": names, "目标值": values})
result.to_excel("results/结果.xlsx", index=False)

禁止依赖 pandas.read_excel() 默认的 header=0 猜测表头,否则第一行数据会被当成列名。未知表头结构或必须精确保留行时使用无隐式推断的读取工具:

from scripts.read_rows import read_excel_rows

rows = read_excel_rows(
    "data/input.xlsx",
    header=False,
    expected_rows=7470,
)
assert rows[0][0] == 399.6747

读取后必须核对首行、末行、原始工作表有效行数和题目声明的记录数;行数不符时立即报错,不得静默继续建模。

使用模板时用 openpyxl.load_workbook() 打开,写入指定单元格后另存新文件。不要删除未知工作表、命名区域、公式或验证规则。

公式重算

openpyxl 不计算公式。修改含公式的工作簿后使用 LibreOffice 隔离重算:

python scripts/recalc.py "/results/结果.xlsx" 60

工具会:

  1. 使用唯一临时 LibreOffice 配置;
  2. 把重算结果写入临时目录;
  3. 检查常见 Excel 错误;
  4. 仅在成功后原子替换目标文件;
  5. 超时、失败或未生成输出时保留原文件。

DOCX 与 XLSX 共用的 OOXML/LibreOffice 基础代码位于 ../docx/scripts/office/,本工具不再维护重复副本。

检查

  • 公式引用和范围正确。
  • 工作表名、列名、数据类型和单位正确。
  • 已显式声明是否有表头,首行、末行和预期数据行数均已核对。
  • #VALUE!#DIV/0!#REF!#NAME?#NULL!#NUM!#N/A
  • 结果与代码终端输出和论文表格一致。
