Appending multiple dataframes to excel on different sheets

May 28, 2022

I would like to add multiple dataframes from a dictionary to one excel file and each dataframe should be written in a sheet. Sheen name is actually the key of the dictionary. The following code

for key in df_dict:
    df = df_dict[key]
    df.to_excel('data-frames.xlsx', sheet_name=key, index=False)

only writes the last dataframe. So, I only see one sheet. On the other hand the append_df_to_excel() method which is described here doesn’t works. I get the error that there is no such method, although the pandas version is 1.4.2.

...
AttributeError: 'DataFrame' object has no attribute 'append_df_to_excel'

In [2]: import pandas as pd
In [2]: print(pd.__version__)
1.4.2

How can I fix that?

>Solution :

Could you try this code?

for key in df_dict:
    df = df_dict[key].copy()
    with pd.ExcelWriter('data-frames.xlsx', mode='a') as writer:  
           df.to_excel(writer, sheet_name=key)
