Trying to export a Spatially Enabled Dataframe, which is converted from excel sheet. column dtypes shows up correct when its in dataframe, but when exporting to geodatbase FC, its only taking column types difintion from first row. For example
COl1   Col2   Col3   Col4
  Null     Null    Null      20
although all columns are showing up as float64 type in dataframe, but when I export it to feature class, Col1,2,3 becomes Text type, and only Col4 remains Double.
