Convert complete excel workbook to SQLite database (All Sheets)
'''
This code uses the openpyxl package for playing around with excel using Python code
to convert complete excel workbook (all sheets) to an SQLite database
The code assumes that the first row of every sheet is the column name
Every sheet is stored in a separate table
The sheet name is assigned as the table name for every sheet
'''
import sqlite3
import openpyxl
from openpyxl import load_workbook
import re
def slugify(text, lower=1):
if lower == 1:
text = text.strip().lower()
text = re.sub(r'[^\w _-]+', '', text)
text = re.sub(r'[- ]+', '_', text)
return text
#Replace with a database name
con = sqlite3.connect('test.db')
#replace with the complete path to youe excel workbook
wb = load_workbook(filename=r'abc.xlsx')
sheets = wb.get_sheet_names()
for sheet in sheets:
ws = wb[sheet]
columns= []
query = 'CREATE TABLE ' + str(slugify(sheet)) + '(ID INTEGER PRIMARY KEY AUTOINCREMENT'
for row in ws.rows[0]:
query += ', ' + slugify(row.value) + ' TEXT'
columns.append(slugify(row.value))
query += ');'
con.execute(query)
tup = []
for i, rows in enumerate(ws):
tuprow = []
if i == 0:
continue
for row in rows:
tuprow.append(unicode(row.value).strip()) if unicode(row.value).strip() != 'None' else tuprow.append('')
tup.append(tuple(tuprow))
insQuery1 = 'INSERT INTO ' + str(slugify(sheet)) + '('
insQuery2 = ''
for col in columns:
insQuery1 += col + ', '
insQuery2 += '?, '
insQuery1 = insQuery1[:-2] + ') VALUES('
insQuery2 = insQuery2[:-2] + ')'
insQuery = insQuery1 + insQuery2
con.executemany(insQuery, tup)
con.commit()
con.close()
