I have tried multiple ways to achieve this for ex: inputpd = pd.DataFrame(inputpd.columns,dtype=str)

But it does not work. sorry for asking this question as i am beginner to spark.

If it's a Pandas DataFrame:

df = df.astype(str)

The easiest way I think it is:

df = df.applymap(str)

df is your dataframe.
