[英]Split cell value that based on a delimiter and insert to a new columns
The header should be written to each new column inserted, and the cell value should split by the "," delimiter. header 应写入每个插入的新列,单元格值应由“,”分隔符分隔。
Example:例子:
Before:前:
Header name ![]() |
another columns from right...![]() |
---|---|
value1![]() |
|
value1,value2,value3![]() |
|
value1,value2![]() |
After:后:
Header name ![]() |
Header name ![]() |
Header name ![]() |
another columns from right...![]() |
---|---|---|---|
value1![]() |
|||
value1![]() |
value2![]() |
value3![]() |
|
value1![]() |
value2![]() |
So far I tried:到目前为止,我尝试过:
Function multipleValues(colName As String)
Set Rng = getHeadersRange(colName)
colNumber = Rng.Columns(Rng.Columns.Count).Column
ColLtr = Cells(1, colNumber).Address(True, False)
ColLtr = Replace(ColLtr, "$1", "")
Dim indexOfWord As Integer
Dim maxValues As Integer
'Find out how many new columns needs to be inserted
Dim item As String, newItem As String
Dim items As Variant, newItems As Variant
maxValues = 0
For Each cell In Rng
items = Split(cell.Value, ",")
If maxValues < UBound(items) Then
maxValues = UBound(items)
End If
Next cell
'Insert new columns
If maxValues > 0 Then
Columns(Rng.Column).Offset(, 1).Resize(, maxValues).Insert
End If
'Duplicate the header to the new columns
'For i = 1 To maxValues
'Cells(1, ColLtr + i).Value = colName
'Next i
'Split the items to columns
For Each cell In Rng
items = Split(cell.Value, ",")
maxValues = UBound(items)
For i = 0 To UBound(items)
firstValue = items(0)
cell.Offset(0, i) = items(i)
cell.Value = firstValue
Next i
Next cell
End Function
Currently, I get the new columns with their values except for the header row values.目前,除了 header 行值之外,我得到了新列及其值。
I would do the following:我会做以下事情:
First find out how many columns need to be added.首先找出需要添加多少列。 We do that by counting the delimiters (commas) in the column and use the maximum + 1 to get the amount of columns we will have in the end after splitting.
我们通过计算列中的分隔符(逗号)来做到这一点,并使用最大值 + 1 来获得拆分后我们最终将拥有的列数。
Then we read the data of the column into a Data
array for faster processing and prepare an Output
array in the calculated size.然后我们将该列的数据读入一个
Data
数组以进行更快的处理,并准备一个计算出的大小的Output
数组。
Then we multiply the header to the Output
array and split the data rows into the output array.然后我们将 header 乘以
Output
数组,并将数据行拆分为 output 数组。
Finally we just need to add the right amount of columns to the right and fill in the data from our array.最后,我们只需要在右侧添加适量的列并填写数组中的数据。
done.完毕。

Public Sub Example()
ExpandColumnByDelimiter Columns(1), ","
End Sub
Public Sub ExpandColumnByDelimiter(ByVal ColumnToExpand As Range, Optional ByVal Delimiter As String = ",")
Dim ws As Worksheet
Set ws = ColumnToExpand.Parent
Dim LastRow As Long
LastRow = ws.Cells(ws.Rows.Count, ColumnToExpand.Column).End(xlUp).Row
' get data address for formula
Dim DataAddress As String
DataAddress = ColumnToExpand.Resize(RowSize:=LastRow - 1, ColumnSize:=1).Offset(RowOffset:=1).Address(True, True, xlA1, True)
' get max number of columns for output
Dim MaxColumns As Long
MaxColumns = Evaluate("=MAX(LEN(" & DataAddress & ")-LEN(SUBSTITUTE(" & DataAddress & ",""" & Delimiter & ""","""")))") / Len(Delimiter) + 1
' read column data into array
Dim Data() As Variant
Data = ColumnToExpand.Resize(RowSize:=LastRow).Value
' prepare output array
Dim Output() As Variant
ReDim Output(1 To LastRow, 1 To MaxColumns) As Variant
' multiply header
Dim iHeader As Long
For iHeader = 1 To MaxColumns
Output(1, iHeader) = Data(1, 1)
Next iHeader
' split data into output array
Dim SplitData() As String
Dim iRow As Long
For iRow = LBound(Data, 1) + 1 To UBound(Data, 1)
SplitData = Split(Data(iRow, 1), Delimiter)
Dim iCol As Long
For iCol = LBound(SplitData) To UBound(SplitData)
Output(iRow, iCol + 1) = SplitData(iCol)
Next iCol
Next iRow
' add new columns to the sheet
ColumnToExpand.Offset(ColumnOffset:=1).Resize(ColumnSize:=MaxColumns - 1).Insert xlShiftToRight
' write the data
ColumnToExpand.Resize(RowSize:=UBound(Output, 1), ColumnSize:=UBound(Output, 2)).Value = Output
End Sub
To turn this要转这个
into this进入这个
/// Edit /// 编辑
And well of course as Siddharth Rout pointed out correcty you can still use the text to column feature if you add in the blank columns that are needed to expand the data.当然,正如 Siddharth Rout 指出的那样,如果您添加扩展数据所需的空白列,您仍然可以使用文本到列功能。 In the end this method would be more efficient.
最后,这种方法会更有效。
Public Sub ExpandColumnByDelimiter(ByVal ColumnToExpand As Range, Optional ByVal Delimiter As String = ",")
Dim ws As Worksheet
Set ws = ColumnToExpand.Parent
Dim LastRow As Long
LastRow = ws.Cells(ws.Rows.Count, ColumnToExpand.Column).End(xlUp).Row
' get data address for formula
Dim DataAddress As String
DataAddress = ColumnToExpand.Resize(RowSize:=LastRow - 1, ColumnSize:=1).Offset(RowOffset:=1).Address(True, True, xlA1, True)
' get max number of columns for output
Dim MaxColumns As Long
MaxColumns = Evaluate("=MAX(LEN(" & DataAddress & ")-LEN(SUBSTITUTE(" & DataAddress & ",""" & Delimiter & ""","""")))") / Len(Delimiter) + 1
' add new columns to the sheet
ColumnToExpand.Offset(ColumnOffset:=1).Resize(ColumnSize:=MaxColumns - 1).Insert xlShiftToRight
' text to column
ColumnToExpand.Resize(RowSize:=LastRow - 1, ColumnSize:=1).Offset(RowOffset:=1) _
.TextToColumns Destination:=ColumnToExpand.Cells(2, 1), DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=False, _
Semicolon:=False, Comma:=False, Space:=False, Other:=True, OtherChar:=Delimiter
' multiply header
ColumnToExpand.Cells(1, 1).Resize(ColumnSize:=MaxColumns).Value = ColumnToExpand.Cells(1, 1).Value
End Sub
Try this (works only in Excel 365).试试这个(仅适用于 Excel 365)。 First section of function should be your delimiter with double quotes and second section should be your range.
function 的第一部分应该是你的双引号分隔符,第二部分应该是你的范围。
Function PC_Split(a As String, b As String)
Dim Text() As String
Text = Split(b, a)
PC_Split = Text
End Function
