Field info tool detects everything as vstring

[rumpa]

I am trying to create a DQC on input file format. input file is in .csv format. the sample file has only 57 rows. I am trying to use Field info tool to detect datatype of each field. But all numeric fields or dates fields are detected as Vstring. Need some help to overcome this issue.

You can add an Auto Field tool after your input to see the closest approximate match of data type which Alteryx thinks is appropriate. Do you have some sample data?
