When we do not know your columns

We show you your own header row and ask which column is which, because we never guess.

Every tool writes its own header row, and we do not hold a verified sample of all of them.

A file we do not recognise is not a failure. We name the fields we could not find, and you point at the right column from your own headers.

We remember your answer for the rest of the file.

We do not guess, because a wrong guess hands you a file full of blank titles.
