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:
import pandas as pd from tkinter import *from tkinter import filedialog from tkinter import messagebox as msg from pandastable import Table from tkintertable import TableCanvas class csv_to_excel: def __init__(self, root): self.root = root self.file_name = '' self.f = Frame(self.root, height = 200, width = 300) # Place the frame on root window self.f.pack() # Creating label widgets self.message_label = Label(self.f, text = 'GeeksForGeeks', font = ('Arial', 19,'underline'), fg = 'Green') self.message_label2 = Label(self.f, text = 'Converter of CSV to Excel file', font = ('Arial', 14,'underline'), fg = 'Red') # Buttons self.convert_button = Button(self.f, text = 'Convert', font = ('Arial', 14), bg = 'Orange', fg = 'Black', command = self.convert_csv_to_xls) self.display_button = Button(self.f, text = 'Display', font = ('Arial', 14), bg = 'Green', fg = 'Black', command = self.display_xls_file) self.exit_button = Button(self.f, text = 'Exit', font = ('Arial', 14), bg = 'Red', fg = 'Black', command = root.destroy) # Placing the widgets using grid manager self.message_label.grid(row = 1, column = 1) self.message_label2.grid(row = 2, column = 1) self.convert_button.grid(row = 3, column = 0, padx = 0, pady = 15) self.display_button.grid(row = 3, column = 1, padx = 10, pady = 15) self.exit_button.grid(row = 3, column = 2, padx = 10, pady = 15) def convert_csv_to_xls(self): try: self.file_name = filedialog.askopenfilename(initialdir = '/Desktop', title = 'Select a CSV file', filetypes = (('csv file','*.csv'), ('csv file','*.csv'))) df = pd.read_csv(self.file_name) # Next - Pandas DF to Excel file on disk if(len(df) == 0): msg.showinfo('No Rows Selected', 'CSV has no rows') else: # saves in the current directory with pd.ExcelWriter('GeeksForGeeks.xls') as writer: df.to_excel(writer,'GFGSheet') writer.save() msg.showinfo('Excel file ceated', 'Excel File created') except FileNotFoundError as e: msg.showerror('Error in opening file', e) def display_xls_file(self): try: self.file_name = filedialog.askopenfilename(initialdir = '/Desktop', title = 'Select a excel file', filetypes = (('excel file','*.xls'), ('excel file','*.xls'))) df = pd.read_excel(self.file_name) if (len(df)== 0): msg.showinfo('No records', 'No records') else: pass # Now display the DF in 'Table' object # under'pandastable' module self.f2 = Frame(self.root, height=200, width=300) self.f2.pack(fill=BOTH,expand=1) self.table = Table(self.f2, dataframe=df,read_only=True) self.table.show() except FileNotFoundError as e: print(e) msg.showerror('Error in opening file',e) # Driver Code root = Tk() root.title('GFG---Convert CSV to Excel File') obj = csv_to_excel(root) root.geometry('800x600') root.mainloop() |
