Export data base to Excel file

piotrbujakowski · 03-25-2023, 12:47 PM

Hi.

I try write code to export data base to Excel file.
Ageing I have a problem with modules.
I try find how install that and still don't works.
Please help, thanks.

# beginning of code

import pandas as pd
import openpyxl

# welcome
print("That is simple data base.")
print("Please input date.")
print('\n')

# input data
username = input("Name: ")
usersurename = input("Surename: ")
age = input("Enter age: ")
height = input("Enter height: ")
yob = input("Enter YoB: ")

# open file
f = open("data_base.txt", "a")

# write date to file
f.write('\n')
f.write("Name: ")
f.write(username)
f.write('\n')
f.write("Surename: ")
f.write(usersurename)
f.write('\n')
f.write("Age: ")
f.write(age)
f.write('\n')
f.write("height: ")
f.write(height)
f.write('\n')
f.write("yob: ")
f.write(yob)
f.write('\n')
f.write('\n')
# close file
f.close()

# open file data base and print data
f = open("data_base.txt", "r")
print(f.read())

# export to excel
df = pd.DataFrame([[username, usersurename, age, height, yob], [12, 22, 32], [31, 32, 33]],
index=['Name', 'Surnename', 'Age', 'height', 'yob'], columns=['a', 'b', 'c'])

print(df)
# end export to excel

# end of code

Bolded a part in your code (and you need to use CODE tags when posting code, to make it easier to read). Did you read that link, and check the things advised?? You don't tell us what version/distro of Linux you're using, or how you installed numpy, or gave us any details. Just posting your code with a VERY well explained error doesn't tell us much.

Provide details, and we can try to help.

After you get numpy fixed.

Code:

import pandas as pd
import openpyxl

# welcome
print('That is simple data base.', 'Please input date.', sep='\n')

# input data
username = input("Name: ")
usersurename = input("Surename: ")
age = input("Enter age: ")
height = input("Enter height: ")
yob = input("Enter YoB: ")

# open file
with open('data_base.txt', 'a') as f:
    f.write(f"\nName: {username}\nSurename: {usersurename}")
    f.write(f"\nAge: {age}\nHeight: {height}\nYob: {yob}\n\n")

# open file data base and print data
with open('data_base.txt', 'r') as f:
    print(f.read())
    
# export to excel
df = pd.DataFrame([[username, usersurename, age, height, yob], 
                        [12, 22, 32], [31, 32, 33]],
index=['Name', 'Surnename', 'Age', 'height', 'yob'], 
                        columns=['a', 'b', 'c'])

print(df)
# end export to excel
# end of code

Is this supposed to tell us something??? You had a very clear error, with instructions on how to fix it, and were asked several questions...none of which you answered. If you're not going to answer the questions asked, there isn't going to be anything we can help you with.

Uh, that does not "export to Excel".

And how did you do that?

If you're using Ubuntu or an Ubuntu-based distro, then the following should work:

Code:

sudo apt-get install python3-pandas

I tested this before posing.

Create Test.db

Code:

#!/usr/bin/python

import sqlite3

try:
    conn = sqlite3.connect("Test.db")
    print("Database Test.db created.")
except:
    print("Database Test.db not created.")
    
c = conn.cursor()
   
c.execute('''CREATE TABLE IF NOT EXISTS files ([files_id] INTEGER PRIMARY KEY, 
            [file_name] TEXT)''')
          
conn.commit()
          
c.execute('''INSERT INTO files (files_id,file_name) VALUES
            (1,'file1'),
            (2,'file2'),
            (3,'file3'),
            (4,'file4'),
            (5,'file5')
          ''')
          
conn.commit()

Make xlsx from Test.db

Code:

#!/usr/bin/python

import sqlite3
import os
import openpyxl
from sqlite3 import Error

DBFILE = "Test.db"

conn = sqlite3.connect(DBFILE)
cursor = conn.cursor()
book = openpyxl.Workbook()
sheet = book.active
 
cursor.execute("SELECT * FROM `files`")
results = cursor.fetchall()
i = 0
for row in results:
    i += 1
    j = 1
for col in row:
    cell = sheet.cell(row = i, column = j)
    cell.value = col
    j += 1
 
book.save("Test.xlsx")
conn.close()

Code:

file Test.db
Test.db: SQLite 3.x database, last written using SQLite version 3040001, file counter 2, database pages 2, cookie 0x1, schema 4, UTF-8, version-valid-for 2

file Test.xlsx
Test.xlsx: Microsoft Excel 2007+

I'd actually advise exporting to CSV (which Excel can open), not directly to Excel, if possible.
