Excel changing syntax after using "text to columns" function (URGENT)

Hi guys, thanks for your quick replies. I am going mentally unstable right now, since I do not have the data without converting the text into columns. The data in this one is with "." seperation at first. I dont mind that. I can easly convert it to ",".

And I also think it has something to do with the difference in notation between "," and "."

Edit: You should be aware the datalogger runs something like Office 2003.

did you post the after-the-fact stuff?

Can you post a slice of the data before it goes through text-to-columns?

If you're having trouble with text-to-columns, I'd like to see what the behavior of the converter is, rather than try to guess based on the ouput.
