如何将 Pandas dataframe 写入现有的 Excel 表？

Question

I would like to write an exisiting Pandas DF to an existing Excel table (or any named range in an Excel sheet for that matter) – essentially replacing the current Excel table with the dataframe. How would you approach this?

Answer 1

You can do that with mode='a'

From the official docs:

with pd.ExcelWriter('output.xlsx',mode='a') as writer:  
    df.to_excel(writer,
                sheet_name='Sheet_name_3',
                startrow=0, 
                startcol=0)

To specify a specific position set startrow , and startcol accordingly.
