Question

我正在尝试阅读Excel 2007工作表。读取Excel工作表的问题在于其所有单元格都具有公式类型的值。

单元格的值如下：

=＆＃39; C：！\ \ ** \ [*** XLSX]的 *＆＃39; G23

当我尝试使用公式评估阅读它时，它给出了以下错误：

Exception in thread "main" java.lang.RuntimeException: Could not resolve external workbook name '/**/**.xlsx'. Workbook environment has not been set up.

工作表具有正确的值，但因为它们是公式类型，当我们尝试评估它时，它会给出公式中引用的excel的错误。

我尝试了以下链接中给出的所有可能方式。 Formula Evaluation Apache但它不起作用。

请帮忙。

Answer 1

我今天有同样的错误。因为由于某些数据丢失问题，我从旧文件创建了新的excel文件并更改了名称。当我在新的excel文件中评估公式时，它使用旧名称给出了此错误。下一行解决了如下问题：

wb.setForceFormulaRecalculation(true)

希望它将对某人有所帮助。

var bcd = sheet1.Workbook.GetCreationHelper().CreateFormulaEvaluator();
bcd.IgnoreMissingWorkbooks = true;
bcd.EvaluateAll();

使用Apache poi
