Convert complete excel workbook to SQLite database (All Sheets)

excel2sql.py

'''
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()

For python3 you will need to replace unicode with str, and the line
for row in ws.rows[0]:
with
for row in next(ws.rows):

Thanks for the code. It was very instructive in creating a larger project.

Hello, thank for code

How can get only 5 first columns ?

Or columns with an exactly name ?

And if columns name are in line 2 ?

Thx

This code is extremely useful. Thank you for sharing it.

for python3 change unicode to str.

Thnks

Great project , and thanks
what if we need it dynamic by uploading excel and the code convert it database
Best regards
