Create a GUI to convert CSV file into excel file using Python
Prerequisites: Python GUI – tkinter, Read csv using pandas
CSV file is a Comma Separated Value file that uses a comma to separate values. It is basically used for exchanging data between different applications. In this, individual rows are separated by a newline. Fields of data in each row are delimited with a comma.
Modules Needed
- Pandas: Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. To install this module type the below command in the terminal.
pip install pandas
- pandastable: This library provides a table widget for Tkinter with plotting and data manipulation functionality. To install this module type the below command in the terminal
pip install pandastable
- tkintertable: This library is used for adding tables to a Tkinter application. To install this library type the below command in the terminal.
pip install tkintertable
Below is the implementation.
Input CSV File:
