## Python Pandas Write DataFrame to Excel

In this section, we will learn about Python Pandas Write DataFrame to Excel.

- Using
we can convert the DataFrame to an Excel file in Pyhton Pandas.`.to_excel()`

- No module named ‘openpyxl’, in case this error is appearing that means you need to install openpyxl package on your system.
- Use
`conda install openpyxl`

if you are using anaconda environment. - Use
`pip install openpyxl`

if using pip. - In our example, we have created a dataframe of cars and this dataframe is written to excel file using Python Pandas

## Python Pandas Write DataFrame to Excel Without Index

In this section, we will learn about Python Pandas write DataFrame to Excel without Index.

- Everytime we export the dataframe index is also exported which becomes problem when same file is exported multiple times.
- As it will have index multiple times which makes no sense. So it is advised to remove the index value before exporting it to a file.
- Using option
**index=False**, will not export an index value in the new file. - Here is the syntax of writing dataframe to excel without index.

`df.to_excel(new_file.xlsl, index=False)`

- Here is the implementation on Jupyter Notebook.

## Python Pandas Write DataFrame to Existing Excel

In this section, we will learn about Python Pandas Write DataFrame to Existing Excel.

- First things in the process is to read or create dataframe that you want to add to the excel file.
- then read the excel file using
**pd.ExcelWriter('exisitingfile.xlsx')** - export the data from sources to writer like this:
`df1.to_excel(writer, sheet_name='Sheet1')`

- here df1 is the first dataframe that we want to add in exisiting dataframe, and we are adding it in a sheet1. Here ‘writer’ will be same for all the dataframes that we want to add into existing dataframe.
- In this end to mark the transaction complete type
`writer.save()`

- Here is the implementation on Jupyter Notebook.

## Python Pandas Export Multiple DataFrames to Excel

In this section, we will learn about Python Pandas Export Multiple DataFrames to Excel.

- Using
**pd.ExcelWriter()**we can read the excel file in Python Pandas. - Using
**df.to_excel()**we can write the excel in Python Pandas. This function accepts writer and sheet_name. Here writer is the valriable assigned to pd.ExcelWriter() function. - Using
**writer.save()**we can commit the changes. - In our example, we have created 3 dataframes and we have created a excel file in which all the data of these 3 dataframe is stored in each sheet.
- Here is the implementation on Jupyter Notebook.
