In this article, I will show you how to fetch MySQL Table into a data frame and then export the data to Microsoft Excel format in Python. We will need two modules in Python, mysql-connector and pandas. With these two modules, we will be able to read MySQL Table and then export to ...
In this code,data_frame.to_excel(excel_file_path, index=False)exports the data from the DataFramedata_frameto an Excel file named ‘exported_data.xlsx’. Theindex=Falseparameter is used to prevent Pandas from writing row indices into the Excel file. ...
When we export a pandasDataFrameto an excel sheet usingthedataframe.to_excel()function, it writes an object into the excel sheet directly. To implement this method, create aDataFrameand then specify the name of the excel file. Now, by using thedataframe.to_excel()function, export a pandas...
