Data format error

"We encountered the following error while fetching additional rows: "DataFormat.Error: We couldn't convert to Number."
Preparing a dataflow with a text file, however i get this message when i scroll down. Cant identify the column/row that its referencing. Datatypes are on autodetect, i have no time/date columns.
I can save and close however data flow doesnt refresh: Error: DataFormat.Error: We couldn't convert to Number.

Hey,

The error usually comes when there is some text characters which cannot be converted into numbers.

To debug, get the distinct values from that column and check  :
