I have a Windows Forms with button click operation.

On button click the specified columns in excel should be exported to html.

I used "SaveAs" method. But not able to open the file format in any browser. Please help me how to export specific columns('B','D') to hmtl with cell color.

What I have tried:

Dim xlApp As Excel.Application

Dim xlWB As Excel.WorkBook

Dim xlSH As Excel.WorkSheet

Dim str_File As String = "C:\Sample.xlsx"

xlApp = New Excel.Application

xlWB = xlApp.Workbooks.Open(str_File)
xlSH = xlWB.WorkSheets("merge") xlSH.SaveAs("C:\Sample.html")

1 solution

_Worksheet.SaveAs(String, Object, Object, Object, Object, Object, Object, Object, Object, Object) Method (Microsoft.Office.Interop.Excel) | Microsoft Docs[^]
XlFileFormat enumeration (Excel) | Microsoft Docs[^]

Why don't you try to specify the format explicitly?
xlSH.SaveAs("C:\Sample.html", XlFileFormat.xlHtml)

(Terrible idea to store anything at the root of a drive. Modern OS's may even prevent you from doing that.)

You have to create another worksheet and copy only desired columns; then export the new worksheet.

You don't have to create another worksheet for this.
Instead, you can specify print area and Excel will export just that area.
For example, try something like this:

xlSH.PageSetup.PrintArea = "B1:D50"
