带有标签的HTML文本，用于Excel单元格中的格式化文本

问题描述 投票：37回答：6

有没有办法获取HTML并将其导入Excel，以便将其格式化为富文本格式（最好使用VBA）？基本上，当我粘贴到Excel单元格时，我希望将其转为：

<html><p>This is a test. Will this text be <b>bold</b> or <i>italic</i></p></html>

进入这个：

这是一个测试。这个文本是粗体还是斜体

是的，这是可能的:)事实上让Internet Explorer为你做脏工作;）

经过试验和测试

我的假设

  1. 我假设html文本在Sheet1的单元格A1中。您也可以使用变量。
  2. 如果你有一个充满html值的列，那么只需将下面的代码放在一个循环中

码

Sub Sample()
    Dim Ie As Object

    Set Ie = CreateObject("InternetExplorer.Application")

    With Ie
        .Visible = False

        .Navigate "about:blank"

        .document.body.InnerHTML = Sheets("Sheet1").Range("A1").Value

        .document.body.createtextrange.execCommand "Copy"
        ActiveSheet.Paste Destination:=Sheets("Sheet1").Range("A1")

        .Quit
    End With
End Sub

您可以将HTML代码复制到剪贴板并将其特殊粘贴为Unicode文本。 Excel将在单元格中呈现HTML。看看这篇文章http://www.dailydoseofexcel.com/archives/2005/02/23/html-in-cells-ii/

帖子中的相关宏代码：

Private Sub Worksheet_Change(ByVal Target As Range)

   Dim objData As DataObject
   Dim sHTML As String
   Dim sSelAdd As String

   Application.EnableEvents = False

   If Target.Cells.Count = 1 Then
      If LCase(Left(Target.Text, 6)) = "<html>" Then
         Set objData = New DataObject

         sHTML = Target.Text

         objData.SetText sHTML
         objData.PutInClipboard

         sSelAdd = Selection.Address
         Target.Select
         Me.PasteSpecial "Unicode Text"
         Me.Range(sSelAdd).Select

      End If
   End If

   Application.EnableEvents = True

End Sub

如果IE示例不起作用，请使用此示例。无论如何，这应该比启动IE实例更快。

这是一个完整的解决方案 http://www.dailydoseofexcel.com/archives/2005/02/23/html-in-cells-ii/

请注意，如果你的innerHTML是所有数字，例如'12345'，那么HTML格式在excel中完全不起作用，因为它对数字的处理方式不同？但最后添加一个字符，例如尾随空格。 12345 +“＆nbsp;”格式好。

Sub test()
    Cells(1, 1).Value = "<HTML>1<font color=blue>a</font>" & _
                        "23<font color=red>4</font></HTML>"
    Dim rng As Range
    Set rng = ActiveSheet.Cells(1, 1)
    Worksheet_Change rng, ActiveSheet
End Sub


Private Sub Worksheet_Change(ByVal Target As Range, ByVal sht As Worksheet)

    Dim objData As DataObject ' Set a reference to MS Forms 2.0
    Dim sHTML As String
    Dim sSelAdd As String

    Application.EnableEvents = False

    If Target.Cells.Count = 1 Then

            Set objData = New DataObject
            sHTML = Target.Text
            objData.SetText sHTML
            objData.PutInClipboard
            Target.Select
            sht.PasteSpecial Format:="Unicode Text"
    End If

    Application.EnableEvents = True

End Sub

我知道这个帖子很古老，但在分配innerHTML后，ExecWB为我工作：

.ExecWB 17, 0
'Select all contents in browser
.ExecWB 12, 2
'Copy them

然后将内容粘贴到Excel中。由于这些方法容易出现运行时错误，但在调试模式下尝试一次或两次后工作正常，您可能必须告诉Excel如果遇到错误再试一次。我通过将此错误处理程序添加到sub解决了这个问题，并且它工作正常：

Sub ApplyHTML()
  On Error GoTo ErrorHandler
    ...
  Exit Sub

ErrorHandler:
    Resume 
    'I.e. re-run the line of code that caused the error
Exit Sub
     
End Sub

我遇到了BornToCode在原始解决方案的评论中首次发现的相同错误。由于不熟悉Excel和VBA，我花了一秒时间才弄清楚如何实现tiQU的解决方案。所以我将它作为“For Dummies”解决方案发布在下面

  1. 首先在Excel中启用开发人员模式：Link
  2. 选择开发人员选项卡> Visual Basic
  3. 单击查看>代码
  4. 粘贴下面的代码，更新需要单元格引用正确的行。
  5. 单击绿色运行箭头或按F5
Sub Sample()
    Dim Ie As Object
    Set Ie = CreateObject("InternetExplorer.Application")
    With Ie
        .Visible = False
        .Navigate "about:blank"
        .document.body.InnerHTML = Sheets("Sheet1").Range("I2").Value
             'update to the cell that contains HTML you want converted
        .ExecWB 17, 0
             'Select all contents in browser
        .ExecWB 12, 2
             'Copy them
        ActiveSheet.Paste Destination:=Sheets("Sheet1").Range("J2")
             'update to cell you want converted HTML pasted in
        .Quit
    End With
End Sub

太好了！非常光滑。

我很失望Excel不允许我们粘贴到合并的单元格，并且还将包含中断的结果粘贴到“目标”单元格下面的连续行中，因为这意味着它对我来说根本不起作用。我尝试了一些调整（unmerge / remerge等），但随后Excel在休息时间丢弃任何东西，所以这是一个死胡同。

最终，我提出了一个例程，它将处理简单的标签，而不是使用导致合并字段问题的“本机”Unicode转换器。希望其他人认为这有用：

Public Sub AddHTMLFormattedText(rngA As Range, strHTML As String, Optional blnShowBadHTMLWarning As Boolean = False)
    ' Adds converts text formatted with basic HTML tags to formatted text in an Excel cell
    ' NOTE: Font Sizes not handled perfectly per HTML standard, but I find this method more useful!

    Dim intStartPos As Integer, intEndPos As Integer, intActualStartPos As Integer, intActualEndPos As Integer
    Dim intFontSizeStartPos As Integer, intFontSizeEndPos As Integer, intFontSize As Integer

    varyTags = Array("<b>", "</b>", "<i>", "</i>", "<u>", "</u>", "<sub>", "</sub>", "<sup>", "</sup>")

    ' Remove unhandled/unneeded tags, convert <br> and <p> tags to line feeds

    strHTML = Replace(strHTML, "</html>", "")

        strHTML = Left$(strHTML, Len(strHTML) - 4)

请注意，这并不关心标记嵌套，而只需要为每个打开的标记使用close标记，并假设最接近开始标记的close标记适用于开始标记。正确嵌套的标签可以正常工作，而不正确的嵌套标签不会被拒绝，可能会也可能不会。
