比较不同列顺序的两个工作表 [英] Comparing two worksheets with different column order

问题描述

我正在尝试比较Excel中的两个工作表，以使用vba查找新的/更新的记录。
（假设工作表1是旧的，工作表2有潜在的新的/更新的条目）

I'm trying to compare two worksheets in excel to find new/updated records using vba. (assume worksheet 1 is old, and worksheet 2 has the potential new/updated entries)

这些工作表有非常相似的信息存储在每个，只是在一个不同的订单。

These sheets have very similar information stored in each, just in a different order.

例如：
工作表1在列E中有街道地址，而工作表2在列H中有街道地址。还有许多其他列这个。

For example: Worksheet 1 has Street Address in Column E whereas Worksheet 2 has the street Address in Column H. There are many other columns like this.

我不太确定从哪里开始。我试图通过剪切和插入来重新排列第二张表中的列，以匹配那些第一张的列，但是这些列非常快速。

I'm not really sure where to start. I tried to rearrange the columns in the second sheet by cutting and inserting to match those of the first, but that got out of hand very quickly.

另外，如果它的一个新记录，需要附加到数据的末尾。

Also, if its a new record, it needs be appended to the end of the data.

推荐答案

**更新以允许定义键列。只需将'iKeyCol = 2'行更改为所需的列。

**Updated to allow defining the 'key' column. Just change the line 'iKeyCol = 2' to the desired column.

这是一些尝试的代码。我太懒了，重新修改了我正在使用的所有代码，所以有些可能是额外的。确保您的工作簿
1.至少有三张（名称Sheet1，Sheet2，NewSheet）
2.具有Sheet1和Sheet2
3. Col1必须在两张表中匹配
4.列数必须在两张表中匹配。
其他col1，其他列可以按任何顺序。

Here is some code to try. I was too lazy to rework all the code I was using, so some of this may be extra for you. Make sure your workbook 1. Has at least three sheets (names 'Sheet1, Sheet2, NewSheet') 2. Has column headers for Sheet1 & Sheet2 3. Col1 must match in both sheets 4. Column count must match in both sheets. Other that col1, other columns can be in any order.

将代码粘贴到新模块中并执行。

Paste the code into a new module and the execute.
