Random data in ADF DataFlow Preview

Question

The question title might sound vague, but that's because I have no idea what's happening in my adf dataflow.

I have a table called table A, when I preview Table A's data in ADF dataflow, I see some of the values spread out randomly.

For example, I have a Column "Name" that contains all string values and no numbers, but I see random numbers after a few rows. Those numbers do not exist like that in the source file.

here is what what I see. Those Highlighted numbers are not supposed to be there

Answer 1

Usually happens if your source file is a delimited file(CSV), if yes, then check if you have some text data with the delimiter.

If yes again, then wrap them in a " " or change delimiter. If it's not a CSV source then will need to further debug.
