Question

Answer 1

If you cannot use the Windows ftp.exe (particularly because it does not support the passive mode and TLS/SSL), you can use another command-line FTP client.

For example to upload a file using WinSCP scripting, use:

Call Shell( _
    "C:\path\WinSCP.com /log=C:\path\excel.log /command " & _
    """open ftp://user:password@example.com/"" " & _
    """put C:\path\file.txt /path/"" " & _
    """exit""")

To ease reading, the above runs these WinSCP commands:

open ftp://user:password@example.com/
put C:\path\file.txt /path/
exit

You can put the commands to a script file and run the script with /script= command-line parameter, similarly to the ftp -s:, instead of the /command.

See the guide to Converting Windows FTP script to WinSCP script.

You can even have WinSCP GUI generate the FTP upload script for you.

---

WinSCP defaults to the passive mode.

You can also use FTPS (TLS/SSL):

open ftpes://user:password@example.com/

---

Alternatively you can use WinSCP .NET assembly via COM from the VBA code.
