Google Apps脚本-将事件从Google表格导出到Google日历-如何阻止它删除电子表格公式？

Question

我一直在尝试创建一个代码，该代码从Google Spreadsheet获取信息，并创建Google Calendar事件。 我对此并不陌生，所以请不要缺乏深入的编码知识！

最初，我使用这篇文章来创建代码： 从电子表格创建Google日历活动，但防止重复

然后，我发现由于电子表格上的行数而导致超时，并且没有创建eventID来避免重复。 我在这里得到了解决的办法！ 通过Google电子表格创建Google日历事件的Google脚本-“超出了最长执行时间”

现在，我意识到它正在覆盖电子表格中的公式，并自动完成每一行，如下所示：

Row 12 - =if(E4="","",E4+1) // Row 13 - =if(C4="","",C4+1) // Row 18 - =if(B4="","","WHC - "&B4) // Row 19 - =if(B4="","","Docs - "&B4)

有谁知道我如何才能停止这样做？

Answer 1

您必须找到解决该问题的方法。

第一种可能性： 仅在没有公式的列上使用数组数据更新工作表，像在另一篇文章中那样继续进行，但是在您的情况下（要跳过多个列），它将很快变得棘手

第二种可能性：（我个人会选择，因为我不是“公式迷”）是按照脚本本身的公式进行操作，即将公式转换为数组级操作。

按照您的示例=if(E4="","",E4+1)会变成类似data[n][4]=data[n][4]==''?'':data[n+1][4]; 如果我了解逻辑（但我不确定...）。

实际上，还有第三个解决方案甚至更简单 （想一想为什么我没有首先考虑它……）您可以保存具有公式的范围，例如，如果col M具有要保留的公式：

var formulM = sheet.getRange('G1:G').getFormulas();

然后，在函数末尾（在全局setValues() ）使用重写公式：

sheet.getRange('G1:G').setFormulas(formulM);

还原所有以前的公式...就这么简单，对需要保留公式的每一列重复一次。
