vba学习系列(9)--按需求计数单元格数量

系列文章目录

前言

一、按需求计数单元格数量

1.需求

一个表中有多个类型的单元格内容,比如:文字、数字、特殊字符、字母+数字......

我们要计数字母+数字的单元格数量

同时提取字母+数字单元格的数字部分,判断数字部分是否相同,然后计数不同的单元格数量

二、使用步骤

1.vba源码

代码如下(示例):

python 复制代码
Sub CountSpecificFormatStrings()
    Dim rng As Range
    Dim cell As Range
    Dim count, countkey As Integer
    Dim regex, regex1 As Object
    Dim cellAddress As String
    Dim numbers As String
    Dim matches As Object
    Dim match As Variant
    Dim cellNumber As String
    Dim cellValue As String
    Dim myCollection As Collection
    Set myCollection = New Collection
    Dim value As Variant
    Dim lastValue As Variant
    Dim uniqueCount As Integer
    Dim ws As Worksheet
    Set ws = ActiveSheet
    Dim cellValueCollection As Collection
    Dim i, j, k As Integer
    Dim valueToAdd As String
    Dim key As Variant
    Dim dict As Object
    Dim myArray As Variant
    Dim item, ele As Variant
    Dim elements As Variant
    Dim uniquekeys As New Collection

    uniqueCount = 0
    lastValue = ""
    Set cellCollection = New Collection
    Set dict = CreateObject("Scripting.Dictionary")
    
    ' 设置要检查的范围
    Set rng = ws.Range("A3:DR200") ' 假设我们在Sheet1的A1:A10范围内查找
    count = 0
    
    ' 创建正则表达式对象
    Set regex = CreateObject("VBScript.RegExp")
    
    ' 设置正则表达式模式:一个字母后面跟随任意数量的数字
    ' 这里的模式是 [A-Za-z][0-9]+,其中 [A-Za-z] 匹配任意一个字母,[0-9]+ 匹配一个或多个数字
    With regex
        .Global = True
        .IgnoreCase = True
        .pattern = "[A-Za-z][0-9]+"
    End With
    
        ' 创建正则表达式对象
    Set regex1 = CreateObject("VBScript.RegExp")
    
    ' 设置正则表达式模式:一个字母后面跟随任意数量的数字
    ' 这里的模式是 [A-Za-z][0-9]+,其中 [A-Za-z] 匹配任意一个字母,[0-9]+ 匹配一个或多个数字
    With regex1
        .Global = True
        .IgnoreCase = True
        .pattern = "\d+"
    End With

    ' 遍历单元格
    For Each cell In rng
        If regex.Test(cell.value) Then ' 如果单元格匹配正则表达式
            count = count + 1 ' 增加计数
    
            Debug.Print "行:" & cell.Row & ",列:" & cell.Column & ",值:" & cell.value
            
            'Set matches = regex1.Execute(cell.Value)
            'For Each match In matches
                'outputString = outputString & match.Value
                'Debug.Print outputString
            'Next match
            'Debug.Print cell.Row & cell.Column
            'Debug.Print Cells(cell.Row, cell.Column).Value
            Set matches = regex1.Execute(Cells(cell.Row, cell.Column).value)
            For Each match In matches
                myCollection.Add match
            Next match
            
        End If
    Next cell
    
    
    For Each item In myCollection
        'Debug.Print item
    Next
    
    countkey = myCollection.count
    
    For i = myCollection.count To 1 Step -1
        For j = 1 To i - 1
            If myCollection(i) = myCollection(j) Then
                myCollection.Remove (i)
                countkey = countkey - 1
                Exit For
            End If
        Next j
    Next i
    
    For Each ele In myCollection
        Debug.Print ele
    Next ele

    ws.Cells(2, 69).value = countkey

    ' 显示计数结果
    MsgBox "有 " & countkey & " 个单元格符合指定格式。"
End Sub

2.整理后

代码如下(示例):

python 复制代码
Sub CountSpecificFormatStrings()
    Dim rng As Range
    Dim cell As Range
    Dim count, countkey As Integer
    Dim regex As Object
    Dim matches As Object
    Dim match As Variant
    Dim myCollection As Collection
    Set myCollection = New Collection
    Dim ws As Worksheet
    Set ws = ActiveSheet
    Dim i, j As Integer
    Dim key As Variant
    Dim item, ele As Variant
    
    ' 设置要检查的范围
    Set rng = ws.Range("A3:DR200") ' 假设我们在Sheet1的A1:A10范围内查找
    count = 0
    
    ' 创建正则表达式对象
    Set regex = CreateObject("VBScript.RegExp")
    
    ' 设置正则表达式模式:一个字母后面跟随任意数量的数字
    ' 这里的模式是 [A-Za-z][0-9]+,其中 [A-Za-z] 匹配任意一个字母,[0-9]+ 匹配一个或多个数字
    With regex
        .Global = True
        .IgnoreCase = True
        .pattern = "[A-Za-z][0-9]+"
    End With
    
        ' 创建正则表达式对象
    Set regex1 = CreateObject("VBScript.RegExp")
    
    ' 设置正则表达式模式:一个字母后面跟随任意数量的数字
    ' 这里的模式是 [A-Za-z][0-9]+,其中 [A-Za-z] 匹配任意一个字母,[0-9]+ 匹配一个或多个数字
    With regex1
        .Global = True
        .IgnoreCase = True
        .pattern = "\d+"
    End With
    
    ' 遍历单元格
    For Each cell In rng
        If regex.Test(cell.value) Then ' 如果单元格匹配正则表达式
            count = count + 1 ' 增加计数
            Debug.Print "行:" & cell.Row & ",列:" & cell.Column & ",值:" & cell.value
            'Set matches = regex1.Execute(cell.Value)
            'For Each match In matches
                'outputString = outputString & match.Value
                'Debug.Print outputString
            'Next match
            'Debug.Print cell.Row & cell.Column
            'Debug.Print Cells(cell.Row, cell.Column).Value
            Set matches = regex1.Execute(Cells(cell.Row, cell.Column).value)
            For Each match In matches
                myCollection.Add match
            Next match
        End If
    Next cell
        
    For Each item In myCollection
        'Debug.Print item
    Next
    countkey = myCollection.count
    For i = myCollection.count To 1 Step -1
        For j = 1 To i - 1
            If myCollection(i) = myCollection(j) Then
                myCollection.Remove (i)
                countkey = countkey - 1
                Exit For
            End If
        Next j
    Next i
    For Each ele In myCollection
        Debug.Print ele
    Next ele
    ws.Cells(2, 69).value = countkey
    
    ' 显示计数结果
    MsgBox "有 " & countkey & " 个单元格符合指定格式。"
End Sub
