Nice tool!

Feedback: I shared it to a friend and his reaction was "bah, it doesn't even work with the example suggested".

Meaning, he saw the placeholder and pressed enter.

Yes, the placeholder is misleading in that it looks like it's been entered into the textbox already and I only need to click "Try me!", but actually I need to type it out first.

It could at least detect that the input is empty instead of saying it failed to parse the input!

You're right, fixing it now.
