KeyError Appears when I convert datatypes despite the fact that I have that column in the dataframe

I have a dataframe with multiple columns that I imported like this:

Flash_Bookings = pd.read_excel(Bookings.xlsx',sheetname='FLASH Bookings' 
,index=False, encoding='utf-8')

Then I convert them to string, int or datetime format depending on what they are:

Flash_Bookings['BookingDate'] = pd.to_datetime(Flash_Bookings['BookingDate'], 
format='%Y-%m-%d')
Flash_Bookings['ContractNo'] = Flash_Bookings['ContractNo'].astype(str)
Flash_Bookings['Rep'] = Flash_Bookings['Rep'].astype(str)

They all work fine (I have other columns in there as well that I didn't include here that all were good except for one "Rep" so the error message I get is:

KeyError: 'Rep'

I even ran:

Flash_Bookings.dtypes

and get:

BookingDate           datetime64[ns]
ContractNo                    object
Rep                           object

so it works perfectly fine for ContractNo which is a string just like Rep.

Any ideas why Rep would not work and how I can fix it?

You probably have an extra space in the header

Try:

Flash_Bookings.columns = Flash_Bookings.columns.str.strip()

Then call

Flash_Bookings['Rep'] = Flash_Bookings['Rep'].astype(str)
