How to set up a function (where its code was obtained from elsewhere) in Excel
1. Copy the function code
2. Open the excel workbook
3. Open Visual Basic Editor (Alt+F11)
4. VBE: Insert > Module > Paste code into "Book1-Module1(Code)" window
Note the name of the function, i.e. If the 1st line is like this:
Function fnConvert2HTML(myCell As Range) As String
Then the name of the function is
fnConvert2HTML
5. Excel: choose a target cell and enter the formula with function and range of cells. In the example above, this would be:
=fnConvert2HTML(A1:B2)
where A1:B2 is the selected range of cells to apply the function to.

This function converts formatted text (say in cell C1) to HTML (say in cell C2). So, in cell C2, enter this "=fnConvert2HTML(C1)", and voila.
Function fnConvert2HTML(myCell As Range) As String Dim bldTagOn, itlTagOn, ulnTagOn, colTagOn As Boolean Dim i, chrCount As Integer Dim chrCol, chrLastCol, htmlTxt, htmlEnd As String bldTagOn = False itlTagOn = False ulnTagOn = False colTagOn = False chrCol = "NONE" 'htmlTxt = "<html>" htmlTxt = "" chrCount = myCell.Characters.Count For i = 1 To chrCount htmlEnd = "" With myCell.Characters(i, 1) If (.Font.Color) Then chrCol = fnGetCol(.Font.Color) If Not colTagOn Then htmlTxt = htmlTxt & "<font color=#" & chrCol & ">" colTagOn = True Else If chrCol <> chrLastCol Then htmlTxt = htmlTxt & "</font><font color=#" & chrCol & ">" End If Else chrCol = "NONE" If colTagOn Then htmlEnd = "</font>" & htmlEnd 'htmlTxt = htmlTxt & "</font>" colTagOn = False End If End If chrLastCol = chrCol If .Font.Bold = True Then If Not bldTagOn Then htmlTxt = htmlTxt & "<b>" bldTagOn = True End If Else If bldTagOn Then 'htmlTxt = htmlTxt & "</b>" htmlEnd = "</b>" & htmlEnd bldTagOn = False End If End If If .Font.Italic = True Then If Not itlTagOn Then htmlTxt = htmlTxt & "<i>" itlTagOn = True End If Else If itlTagOn Then 'htmlTxt = htmlTxt & "</i>" htmlEnd = "</i>" & htmlEnd itlTagOn = False End If End If If .Font.Underline > 0 Then If Not ulnTagOn Then htmlTxt = htmlTxt & "<u>" ulnTagOn = True End If Else If ulnTagOn Then 'htmlTxt = htmlTxt & "</u>" htmlEnd = "</u>" & htmlEnd ulnTagOn = False End If End If If (Asc(.Text) = 10) Then htmlTxt = htmlTxt & htmlEnd & "<br>" Else htmlTxt = htmlTxt & htmlEnd & .Text End If End With Next If colTagOn Then htmlTxt = htmlTxt & "</font>" colTagOn = False End If If bldTagOn Then htmlTxt = htmlTxt & "</b>" bldTagOn = False End If If itlTagOn Then htmlTxt = htmlTxt & "</i>" itlTagOn = False End If If ulnTagOn Then htmlTxt = htmlTxt & "</u>" ulnTagOn = False End If 'htmlTxt = htmlTxt & "</html>" fnConvert2HTML = htmlTxt End Function Function fnGetCol(strCol As String) As String Dim rVal, gVal, bVal As String strCol = Right("000000" & Hex(strCol), 6) bVal = Left(strCol, 2) gVal = Mid(strCol, 3, 2) rVal = Right(strCol, 2) fnGetCol = rVal & gVal & bVal End FunctionCredit http://stackoverflow.com/a/33796622
Tip: To remove rows containing a formula without causing the spreadsheet to hang, delete the cell containing the formula (in that row), then delete the row.
