Remove data connection of Excel Spreadsheet automatically - excel

Question

I need to automatize the following operation:
Open a Excel file at a scheduled time
(I configured its data connection so that the data automatically gets
updated)
Save a Copy of that file, WITHOUT including the data connection.
That report is sent to the customer and therefore can't possible include the query code.
The opening, updating and saving as a copy is not a problem and I will do it with a scripting tool that creates a Windows exe-file that then can be launched at the time I schedule it in Windows TaskScheduler.
But how can I manage to eliminate the data connection?
Regard,
Martin

Answer 1

Use a Workbook_Open event, which runs when the file is opened. Then use the scripting tool to open the file and the VBA should run automatically.

Answer 2

If you are using Excel Interop, you can use this code
using Excel = Microsoft.Office.Interop.Excel;
Excel.Application app = new Excel.Application();
app.DisplayAlerts = false;
Excel.Workbook wb = app.Workbooks.Open(filepath);
int count_conn = wb.Connections.Count;
if (count_conn > 0)
{
for (int i = 1; i <= wb.Connections.Count; i++)
{
wb.Connections[i].Delete();
i = i - 1;
}
count_conn = wb.Connections.Count;
wb.Save(); // Save workbook
}
wb.Save();
wb.Close();
app.Quit();
if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
Marshal.ReleaseComObject(wb);
Marshal.ReleaseComObject(app);
}
