提问者在定义的列式布局中具有三张工作表 - 每个数据集基本上有几行和几列（每个时间段一个）。这些表格没有被替换，但寻求一个总结版本，可以使用过滤来有效地关注相关数据。因此，每张工作表都会从列格式转换为逐行格式。
这个过程本身很简单。源数据包含 64 个产品，每个产品有 8 个数据行。输出记录为@1,350。
提问者的代码在数据到输出格式的转换上挂了。每个产品使用 8 行数据很重要，代码包括检查数据总行数除以 8 的商是否为整数。此外，源表和输出表的名称按名称 (getSheetByName) 调用，因此代码可以轻松应用于任何命名的输入表和任何命名的输出表。唯一的条件是两张表都必须事先存在。
对提问者的代码打嗝的初步解决是成功的，并且使用 getDataRange 和 getValues before 循环的方法大大提高了性能。有两个循环；一个垂直方向，在数据行中移动；第二个是水平方向的，穿过与时间相关的列。然而，性能最初非常低效，代码在完成之前就超时了。
我修改了代码以构建单个二维数组，并在循环结束时将其保存到输出表一次。这对性能产生了巨大的影响。完成的总时间从几分钟减少到不到 5 秒。

更新
提问者代码的第二个元素处理在对“类别”表进行更改时将数据更新到“输出表”。提问者的更新代码没问题，但缺少将类别表上的源范围转换为在输出表上建立目标范围。
解决方案涉及基于数学数字序列的量规。在这种情况下，数学序列是源工作表上产品的行号；每个产品占8行，第一行是#10，所以顺序是10,18,26,34....
onEdit 返回已更改单元格的范围，getRow 和getColumn 可用于建立已更改单元格的坐标。挑战在于，了解实际更改的行号，确定实际行号代表的行序列中的数字（以及产品名称）。更改的行也极不可能（八比一）与产品编号的第一行重合。
因此有必要将算法应用于数学序列 - 两次。确定数字序列中第 n 个数字的公式是 An = A1 + (D x(n-1))，其中 A1 是第一行的数字（在我们的例子中为 10），D= 每个数字之间的差在序列中（在我们的例子中为 8），并且 n = 序列中的数字（在我们的例子中，更改的行号）。
第一遍是在实际变化的行所代表的数字（产品组）序列中建立位置编号。结果很可能不是整数，即它与产品组的第一行不一致。因此，将结果向下舍入到最接近的整数，并再次处理算法。
不过这一次我们知道了序列号的位置，我们通过求解找到该数字的值。在这种情况下，公式为 ((An-A1)/D)+1。这将返回 Source 表中与相关产品组的第一行相对应的行号。我们使用它来识别更改的字段类型（类别、显示等）。
列号表示周数。第 1 周从 F 列开始，因此get column 使我们能够确定更改是否发生在一周列中（或者是否发生在 F 列的左侧）。如果在左侧，则“不是我的问题”，如果在 F 或更高，则需要注明。
最后，我们为目标表执行getRangeValue，并在 A 列中查找周数的匹配项，并在 B 列中查找截断的产品名称。这为 setValue 提供了新值的坐标从 OnEdit 跟踪。
