Custom path for "Write delimited spreadsheet"

[mre@otenet.gr]

I am trying to add the file extension after the user selects the file name. Specifically, when the user clicks a button I would like to open a windows explorer where I enter the desired file name for my spreadsheet. After that I would like to add ".csv" programmatically. I can't seem to figure out how to do this. 

I tried to convert the path to a string, add the ".csv" and the turn the string back to a path. When I add this before the "Write delimited spreadsheet" the program crashes (img1). When I add if after the program opens the windows dialog properly but ignores the ".csv" (img2).

I am new to this, any help is much appreciated.

Hi,

Use the "File Dialog" Express VI (Advanced File Functions palette) with the appropriate pattern. This will automatically add the extension in case the user does not type it explicitly:

P.S.: If you want to do it on an already chosen path (without the dialog box):
