使用pandas库，我们可以轻松地实现统计不重复个数的功能。以下是一个简单的示例：df.drop_duplicates().groupby('地区').count()这句代码首先使用drop_duplicates()方法去除数据中的重复行，然后通过groupby('地区')按照地区进行分组，最后使用count()方法计算每个地区的不重复个数。panda
Sub CalculateDuplicates() Dim lastRow As Long Dim i As Long Dim dict As Object Set dict = CreateObject("Scripting.Dictionary") lastRow = Cells(Rows.Count, 1).End(xlUp).Row For i = 2 To lastRow If Not dict.exists(Cells(i, 1).Value) Then dict.Add Cells(i, 1).Value, 1 Else di...
五、使用公式查找重复数据 (Using Formulas to Find Duplicates) 除了使用Excel的内置功能,用户还可以利用公式来查找重复数据。常用的公式包括COUNTIF和IF函数。以下是一个示例: 使用COUNTIF函数:在一个新的列中输入以下公式: =IF(COUNTIF(A:A, A1) > 1, "重复", "唯一") 这个公式会检查A列中每个单元格的...
Sub FindDuplicates() Dim ws As Worksheet Dim rngA As Range, rngB As Range, cell As Range Set ws = ThisWorkbook.Sheets("Sheet1") Set rngA = ws.Range("A1:A100") Set rngB = ws.Range("B1:B100") For Each cell In rngA If Application.WorksheetFunction.CountIf(rngB, cell.Value) > ...
COUNTIF函数可以用来计算某个范围内满足特定条件的单元格数量。通过结合这个函数,用户可以在新列中标记出重复数据。步骤如下: 在数据旁边插入一列,假设数据在A列。 在B2单元格中输入公式:=IF(COUNTIF(A:A, A2) > 1, "重复", "唯一")。 将公式向下拖动,应用到整个列。
Sub CountDuplicates() Dim ws As Worksheet Dim rng As Range Dim cell As Range Dim count As Integer Dim value As Variant Set ws = ThisWorkbook.Sheets("Sheet1") Set rng = ws.Range("A1:A100") value = "特定值" count = 0 For Each cell In rng ...
Sub MergeDuplicates()Dim rng As RangeDim cell As Range Set rng = Selection With CreateObject("Scripting.Dictionary").CompareMode = vbTextCompare For Each cell In rng If cell <> "" Then .Item(cell.Value) = "" End IfNext cell rng.ClearContentsrng.Resize(.Count).Value = Application.Transpose...
Sub CountDuplicates() Dim dict As Object Set dict = CreateObject("Scripting.Dictionary") Dim cell As Range For Each cell In Range("A2:A" & Cells(Rows.Count, 1).End(xlUp).Row) If Not dict.exists(cell.Value) Then dict.Add cell.Value, 1 ...
Sub HighlightDuplicates() Dim ws As Worksheet Dim rng As Range Dim cell As Range Dim dict As Object Set ws = ThisWorkbook.Sheets("Sheet1") Set rng = ws.Range("A1:A100") Set dict = CreateObject("Scripting.Dictionary") For Each cell In rng If Not IsEmpty(cell.Value) Then If dict....
