Export grid rows > File (Confirm on overwrite)

Could you please implement a check to see if a file exists and make a user confirms file overwrite?

You should be asked to confirm overwriting when you click the "export" button, not when you click the radio button. See attached screeny.

I just realized that the extension changes based on output format. I had a long path in the File box and did not see it changes when you click radio buttons in Output format section.

Sorry for the confusion - I reacted to soon.

Well, that probably means this automatic extension changing should be enhanced - hidden or silent automatisms are mostly causing some confusion. Probably I can auto-scroll the input box to the right, so the user sees the change when clicking a radio button.
