Excel在* .xlsx中找到了不可读的内容

问题描述 投票：6回答：6

我正在从代码生成excel模板。当我运行该工件来创建我的WorkBook时，我没有在代码中出错，但是当我打开Excel文档时，我收到一个错误，指示该文件不可读。无论如何我能够点击打开它，我收到以下消息

删除记录：/xl/workbook.xml部分（工作簿）中的工作表属性

知道我的代码中可能有什么问题吗？

在我的具体情况下，由于工作表名称太长，我遇到了这个问题。这就是发生在我身上的事情：

  • 在我的程序的第一次运行中，我试图创建具有非常大名称的工作表。
  • Excel会自动将大名称裁剪为31个字符。没有例外被抛出。也就是说，我以为我正在保存原来的大牌，但我实际上是在保存31个字符的长裁剪字符串。
  • 在我的程序的第二次运行中，我正在检查这个特定的工作表是否已经存在，但我认为它不存在，因为现有的工作表被裁剪了。
  • 我再次保存工作表。没有异常抛出，但是，新的也被裁剪，现在XML包含同一工作表的2个定义。
  • 这会导致Excel尝试修复生成的电子表格。即使它工作正常，我认为它只是丢掉第二个并使用第一个，这不是我想要的。

我通过在所有比较之前预先裁剪31个字符来解决问题。现在它完美无缺

我知道很久以前就问过这个问题，我认为我的经验会解决某些问题。所以我在这里发布我的答案。

我遇到了类似的问题。这是因为没有。工作表名称中的字符超出限制31.工作表名称字符必须<= 31。

创建时不会抛出任何异常，但在Microsoft Excel中打开时会出错。

Open XML SDK不会限制您生成有效文档。但是，有OpenXmlValidator类可用于报告生成的文档中的任何错误。请参阅this，它有一个很好的例子。

我也有这个错误，因为我使用0作为我的SheetId，类似于：

var sheet1 = new Sheet() { Name = "Test", SheetId = (UInt32Value)0U, Id = "rId1" };

Excel从1开始计数，而不是0.这不仅适用于行号，也适用于工作表编号。

是的，正如Murugesan Said在上面的评论中，我通过重命名我的Excel文档的文件名来修复此错误。例如：在我的例子中，文档的名称是“我的样本导出数据表”。我已将文件重命名为'MySampleExportDataSheet'，之后一切运行良好。

在我的例子中，标签名称由单引号组成，即：“我的标签”。 我只是省略了它们：

title = title.replace(/'/g, "");
