我有一张超过 10000 行的工作表,但数据来自 2 个来源,因此相同的唯一键组合存在重复项。因此,假设 A 列和 B 列是唯一标识符。C 到 K 列包含有关由唯一键指定的项目的数据。我需要检查是否第二次出现唯一键组合,如果是,第二次出现的 C 到 K 列中的数据是否与第一次出现相同。如果它们相同,则将该行复制到工作表 2。
Have you tried using vlookup? When you do this in both directions, you know what the differences are between the two lists. When doing this, make sure that things like spaces are exactly the same. Try using trim on both lists first to remove extra spaces.
