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,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):

        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 ------"
