Data tools work with two panes: you paste your data on the left and read the result on the right. There is no file to pick; you can copy the output or download it as a file.
The usual snag in table conversion is the delimiter — spreadsheet exports from some locales use semicolons instead of commas. The tools detect the delimiter, but glancing at the first row to confirm the result is a good habit.
