python:excel转sqlite

python环境的安装配置就不说了,个人喜欢pydev的开发环境。

python解析excel需要使用第三方的库,可视化专题,这里选择使用xlrd

先看excel内容:

然后是生成的数据库:


下面是源代码:

[python]
#!/usr/bin/python
# encoding=utf-8

from xlrd import open_workbook
import sqlite3
import types

def read_excel(sheet):
# 判断有效sheet
if sheet.nrows > 0 and sheet.ncols > 0:
for row in range(1, sheet.nrows):
row_data = []
for col in range(sheet.ncols):
data = sheet.cell(row, col).value
# excel表格内容数据类型转换 float->int,unicode->utf-8
if type(data) is types.UnicodeType: data = data.encode("utf-8")
elif type(data) is types.FloatType: data = int(data)
row_data.append(data)
check_data_length(row_data)

# 检查row_data长度
def check_data_length(row_data):
if len(row_data) == 3:
insert_sqlite(row_data)

def insert_sqlite(row_data):
# 打开数据库(不存在时会创建数据库)
con = sqlite3.connect("test.db")
cur = con.cursor()
try:
cur.execute("create table if not exists contacts(_id integer primary key "\
"autoincrement,name text,age integer,number integer)")
# 插入数据不要使用拼接字符串的方式,容易收到sql注入攻击
cur.execute("insert into contacts(name,age,number) values(?,?,?)", row_data)
con.commit()
except sqlite3.Error as e:
print "An error occurred: %s", e.args[0]
finally:
cur.close
con.close


xls_file = "test.xls"
book = open_workbook(xls_file)

for sheet in book.sheets():
read_excel(sheet)
print "------ Done ------"

#!/usr/bin/python
# encoding=utf-8
