我尝试比较excel中的两个工作表，以便使用vba查找新的/更新的记录。 （假设工作表1已旧，而工作表2具有潜在的新/更新条目）
这些表格中存储的信息非常相似，只是顺序不同。
例如： 工作表1在E列中具有街道地址，而工作表2在列H中具有街道地址。还有许多其他列如此。
我不确定从哪里开始。我尝试通过切割和插入来重新排列第二张纸中的列，以匹配第一张纸中的列，但这很快就失控了。
此外，如果是新记录，则需要将其附加到数据的末尾。
答案 0 :(得分：0)
**已更新以允许定义“密钥”列。只需将'iKeyCol = 2'行更改为所需的列。
这是一些尝试的代码。我懒得去修改我正在使用的所有代码，所以其中一些可能对你来说是额外的。确保您的工作簿 1.至少有三张（名称'Sheet1，Sheet2，NewSheet'） 2.具有Sheet1＆amp;的列标题。 Sheet2中 3. Col1必须在两张纸上都匹配 4.两列中的列数必须匹配。 其他col1，其他列可以是任何顺序。
将代码粘贴到新模块中并执行。
如果您有问题，请告诉我。
