Python实现锁定指定Excel单元格区域

pip install Spire.Xls.Free

# 加载Excel文件
workbook = Workbook()
workbook.LoadFromFile("demo.xlsx")
worksheet = workbook.Worksheets[0]

# 全局解锁所有单元格（核心）
worksheet.Range.Style.Locked = False

# 锁定指定区域（支持单元格、行列、区域）
# 示例1：锁定单个单元格 A1
worksheet.Range["A1"].Style.Locked = True
# 示例2：锁定区域 A1:C5
worksheet.Range["A1:C5"].Style.Locked = True
# 示例3：锁定第1行（表头）
worksheet.Rows[0].Style.Locked = True
# 示例4：锁定A列（固定字段）
worksheet.Columns[0].Style.Locked = True

# 设置工作表密码保护
worksheet.Protect("Admin@2025")

# 保存文件并释放资源
workbook.SaveToFile("指定区域锁定.xlsx", ExcelVersion.Version2016)
workbook.Dispose()
