df["Dt_Customer"] = pd.to_datetime(df["Dt_Customer"],format='%d-%m-%y')
I have tried to convert the date column, the dataset contains more than 1 million rows... I have to find the date rows which are not getting converted.
TypeError: Unrecognized value type: <class 'str'>
During handling of the above exception, another exception occurred:

CodePudding user response:
you could try a loop with try and except:
causing_error_list = []
for x in df["Dt_Customer"].values:
try:
pd.to_datetime(x,format='%d-%m-%y')
except:
causing_error_list.append(x)
