Extracting a URL from hyperlinked text in Excel cell
I have a table full of Hyperlinked text in excel, so it's basically a bunch of names but when I click on one, it takes me to some URL in my default browser.
So I am extracting text from this excel table in my program, but the value I get when I extract from these hyperlink cells is that of the string inside, when I want the URL the string is linked to in the excel file.
So I'm thinking there are two ways to do this. Either I can convert all the hyperlinked text in the excel file to the corresponding URLs, or I can use C# to somehow extract the URL value from the cell and not the text.
I don't know how to do either of these things, but any help would be greatly appreciated.
C# code so far:
Excel.ApplicationClass excelApp = new Excel.ApplicationClass();
//excelApp.Visible = true;
Excel.Workbook excelWorkbook =
excelApp.Workbooks.Open("C:\\Users\\use\\Desktop\\list.xls开发者_Go百科",
0, false, 5, "", "",false, Excel.XlPlatform.xlWindows, "",
true, false, 0, true, false, false);
Excel.Sheets excelSheets = excelWorkbook.Worksheets;
string currentSheet = "Sheet1";
Excel.Worksheet xlws = (Excel.Worksheet)excelSheets.get_Item(currentSheet);
string myString = ((Excel.Range)xlws.Cells[2, 1]).Value.ToString();
As for the excel file, it's just one long row of names hyperlinked. For instance cell A2 would contain the text:
Yummy cookie recipe
And I want to extract the string:
http://allrecipes.com//Recipes/desserts/cookies/Main.aspx
You could use a vba macro:
Hit Alt+F11 to open the VBA editor and paste in the following:
Function URL(rg As Range) As String
Dim Hyper As Hyperlink
Set Hyper = rg.Hyperlinks.Item(1)
URL = Hyper.Address
End Function
And then you can use it in your Worksheet, like this:
=URL(B4)
In your code just add
string myString = ((Excel.Range)xlws.Cells[2, 1]).Cells.Hyperlinks[1].Address;
I obviously recommend doing some checks before accessing the "Hyperlinks" property.
VBA function:
- Hit Alt+F11 (Opens Visual Basic Editor)
- Click on Insert -> Module (adds a module to your excel file)
- Paste the code below for the function of GETURL
- Hit Alt+Q (Closes the Visual Basic Editor)
Now use the =GETURL(cell)
to get the URL
Example: =GETURL(A1)
will return the URL for the Hyperlink displayed in cell A1
Function GETURL(HyperlinkCell As Range)
GETURL = HyperlinkCell.Hyperlinks(1).Address
End Function
Source
Use Visual Studio Tools for Office (VSTO) to open Excel workbook and extract all hyperlinks.
I put a hyperlink into A1 of Sheet1 in Book1.xlsx: text = "example.com, address = "http://www.example.com"
_Application app = null;
try
{
app = new Application();
string path = @"c:\temp\Book1.xlsx";
var workbook = app.Workbooks.Open(path, 0, true, 5, "", "", true, XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
var sheets = workbook.Worksheets;
var sheet = (Worksheet)sheets.get_Item("Sheet1");
var range = sheet.get_Range("A1", "A1");
var hyperlinks = range.Cells.Hyperlinks.OfType<Hyperlink>();
foreach (var h in hyperlinks)
{
Console.WriteLine("text: {0}, address: {1}", h.TextToDisplay, h.Address);
}
}
finally
{
if (app != null)
app.Quit();
}
Output:
text: example.com, address: http://www.example.com/
why not use Uri class to convert string into URL:
Uri uri = new Uri("http://myUrl/test.html");
You can use VBA code to achieve this.
Press Alt
+ F11
to open VB editor, Insert a Module
and paste the code below:
Sub run()
On Error Resume Next
For Each hLink In Selection
Range(hLink.Address).Offset(0, 1) = hLink.Hyperlinks(1).Address
Next
End Sub
Save your excel file[in excel 2007 and above save as macro enabled...]
Try this:
Excel.Application appExcel = new Excel.Application();
Excel.Workbooks workBooks = appExcel.Workbooks;
Excel.Workbook excelSheet = workBooks.Open("......EditPath", false, ReadOnly: true);
foreach (Excel.Worksheet worksheet in excelSheet.Worksheets)
{
Excel.Hyperlinks hyperLinks = worksheet.Hyperlinks;
foreach (Excel.Hyperlink lin in hyperLinks)
{
System.Diagnostics.Debug.WriteLine("# LINK: adress:" + lin.Address);
}
}
I just ran into this issue and this is what worked for me:
I used the FormulaR1C1 extension method for a range. So my code looked like this:
for (int r = 2; r <= sheetRange.Rows.Count; r++)
{
documentRecord = new List<string>();
for (int c = 1; c <= wkCol; c++)
{
documentRecord.Add(sheetRange.Cells[r, c].FormulaR1C1);
}
AllRecords.Add(documentRecord);
}
When the record is added to the list of records, the value of whatever the cell range was is formatted into a clickable-hyperlink.
