function - Exceeding Max Char Limit in Excel

Question

How do I use more than 255 characters in Excel's CONCATENATE function? I am actually also using the CONCATENATE function within the HYPERLINK function in EXCEL. An example looks like this:

=HYPERLINK(CONCATENATE("http://www.google/com/morethan255charsmorethan255charsmorethan255charsmorethan255charsmorethan255charsmorethan255charsmorethan255charsmorethan255charsmorethan255charsmorethan255chars","morethan255chars morethan255charsmorethan255charsmorethan255charsmorethan25"),"link");

UPDATE: It's not issue with CONCATENATE function, but an issue with the first parameter of the HYPERLINK function. Using a string longer than 255 characters directly/indirectly (ex: =HYPERLINK(K204,"link") where K204 contains the 256-character length link) fails the HYPERLINK function

I realize that I can use a URL shortener, but I am doing this for ALOT of links which would require ALOT of manual use of the URL shortener.

Answer 1

UPDATE: Because of Karls comment I revisited my answer an found out, that Excel 2007 does not seem to allow User Defined Functions to set hyperlinks anymore (quite sensibly, see my own comment in the code). So the original code (below the line) does not work in more recent versions of Excel (I haven't tested Excel 2010 but I assume the result is the same). For historical reasons I do not delete the old code (an editor might think otherwise -- feel free to edit/ delete accordingly).

So what remains is to set long hyperlinks programatically, e.g.

Sub insertVeryLongHyperlink()

    Dim curCell As Range
    Dim longHyperlink As String

    Set curCell = Range("A1")   ' or use any cell-reference
    longHyperlink = "http://www.veryLongURL.com/abcde"  ' Or a Cell reference like [C1]

    curCell.Hyperlinks.Add Anchor:=curCell, _
                    Address:=longHyperlink, _
                    SubAddress:="", _
                    ScreenTip:=" - Click here to follow the hyperlink", _
                    TextToDisplay:="Long Hyperlink"

End Sub

---

What follows does not work in Excel 2010 anymore; see my comment above

The "copy the hyperlink from Word and paste into Excel" got me thinking. So obviously the limit is both in the built-in HYPERLINK-function and in the dialog-window 'edit hyperlink'. On the other hand it should be -- and actually is -- possible to set longer hyperlinks via VBA.

This code does not work in Excel 2010 anymore

Function myHyperlink(cell As Range, _
                        hyperlinkAddress As String, _
                        Optional TextToDisplay As Variant, _
                        Optional ScreenTip As Variant)

    ' Inserts a Hyperlink
    '   at the position     cell (this should be the position where the UDF is used,
    '                       since the return value of the UDF is = TextToDisplay)
    '   with the            hyperlinkAddress
    '   optional            TextToDisplay
    '   optional            ScreenTip

    ' #######################################
    ' Warning Warning Warning Warning Warning
    ' #######################################

    ' 1) Since it is really bad practice to have a function perform procedural
    '    tasks, you should not do this.
    ' 2) You have no garantee, the link is updated when the value hyperlinkAddress changes

    ' USE AT YOUR ONE RISK AND ONLY IN CASE OF EMERGENCIES :-)


    ' If more than one cell is selected as target range,
    ' use the top left cell
    Set cell = cell.Resize(1, 1)

    If IsMissing(TextToDisplay) Then
        TextToDisplay = hyperlinkAddress
    End If

    If IsMissing(ScreenTip) Then
        ScreenTip = hyperlinkAddress & " - Click here to follow the hyperlink"
    End If

    cell.Hyperlinks.Add Anchor:=ActiveCell, _
                        Address:=hyperlinkAddress, _
                        SubAddress:="", _
                        ScreenTip:=ScreenTip, _
                        TextToDisplay:=TextToDisplay

    ' There doesn't seem to be another way to set TextToDisplay
    myHyperlink = TextToDisplay

End Function

Use as a normal Excel-function, but be sure to add the current cell as first parameter (i.e. the following formula is inserted in cell A1)

=myHyperlink(A1,B1)
=myHyperlink(A1,B1,"TextToDisplay", "ScreenTip")

You can neither pull the formula down nor copy it to another cell. If you do that you have to let the formula be recalculated (neither ALT-CTRL-F9 nor ALT-CTRL-SHIFT-F9 as force recalculate seem to work) so go into each cell, press F2 to activate it and finish with Return.

I hope I am not helping you to screw up too many Excel-Workbooks.

It is probably safer to write an VBA that is explicitly started that iterates through a list and writes to hyperlinks. That way they can reused and there are no functions.
