python转换excel成py文件
文件结构如下:
originExcelFolder放用来转换的excel文件。
targetPyFolder用来存放最后生产的py文件。
setting.py用来配置excel表到py的对应关系。
excel2py.py是主要的处理文件。
Excel文件,A注意表名字,B注意sheet名字。
代码如下:
setting.py
#!/usr/bin/env python #-*- coding: utf-8 -*- # setting.py # 定义生成py表的格式 Dict ={ "student":{ "id": {‘type‘:int, ‘default‘: 0}, "name":{‘type‘:str, ‘default‘: None}, "age":{‘type‘:int, ‘default‘: 0}, "sex":{‘type‘:str, ‘default‘: ‘F‘}, } }
excel2.py
#!/usr/bin/env python #-*- coding: utf-8 -*- # transfer excel to py # 处理excel表格生成对应的py文件 from openpyxl import Workbook from openpyxl import load_workbook import sys import os import time from setting import Dict as tranDict TARGET_PY_PATH = "targetPyFolder/" ORIGIN_EXCEL_PATH = "./originExcelFolder/" LOG_LEVEL_INFO = "INFO" LOG_LEVEL_DEBUG = "DEBUG" LOG_LEVEL_ERR = "ERROR" class Excel2py: def __init__(self): self.init() def init(self): self.tempSheetName = None self.tempFileName = None self.target_dict = {} def handleFiles(self): # 切换到handleExcel所在的那个路径 os.chdir(sys.path[0]) # 加载已经存在的excel,(这时候excel与.py文件在同一级目录下) self.tempFileName = ORIGIN_EXCEL_PATH + "test.xlsx" wb = load_workbook(self.tempFileName) # 所有的页的名字 sheetNames = wb.sheetnames # 这里只取出了第一个页来处理, self.tempSheetName = str(sheetNames[0]) ws = wb[self.tempSheetName] # 表的关键字 key_dict = {} # 目标字典 self.target_dict = {} # 取出关键字 for column_index in range(2,ws.max_column+1): val = ws.cell(row=2, column=column_index).value val = str(val) if val: key_dict[column_index] = val # 遍历表的每行 for row_index in range(3, ws.max_row+1): temp_dict = {} for index in key_dict: val = ws.cell(row=row_index,column=index).value # 类型处理 val = self.handleType(self.tempSheetName,key_dict[index],val) item_id = int(ws.cell(row=row_index,column=1).value) temp_dict[key_dict[index]] = val self.target_dict[item_id] = temp_dict self.writeToPy() def handleType(self,sheetName,stype,value): """ 数据类型处理 """ typeDict = tranDict[sheetName].get(stype) rtnValue = typeDict[‘default‘] if value is None or value == "None": rtnValue = typeDict[‘default‘] elif not isinstance(value, typeDict[‘type‘]): rtnValue = (typeDict[‘type‘])(value) # 异常处理--Todo # 写处理日志-Todo else: rtnValue = value return rtnValue def writeToPy(self,): """ 写成py文件 """ fileName = TARGET_PY_PATH + self.tempSheetName + ".py" if os.path.exists(fileName): os.remove(fileName) pyFile = open(fileName,‘a‘) ids = self.target_dict.keys() ids.sort() pyFile.write("\nDict = {\n\n") for id in ids: pyFile.write(str(id)+":"+str(self.target_dict[id])) pyFile.write(",\n") pyFile.write("\n}\n") #pyFile.flush() pyFile.close() logInfo = ‘=========transfer sheet:‘ + self.tempSheetName + " success" print ‘=========logInfo:‘, logInfo self.tranlog(self.tempFileName, self.tempSheetName,LOG_LEVEL_INFO, logInfo) def tranlog(self, excelName, sheetName, logLevel, logInfo): """ 写转换日志 """ logFile = "log.log" pyFile = open(logFile,‘a‘) logMsg = ‘\n‘+logLevel+"__"+str(time.time())+"__"+excelName.split(‘/‘)[-1]+"_"+sheetName+": "+logInfo pyFile.write(logMsg) # pyFile.flush() pyFile.close() if __name__ == "__main__": Excel2pyObj = Excel2py() Excel2pyObj.handleFiles()
注意:这里只处理了一个表的一个sheet,如果想要处理多个表多个sheet可稍作修改即可。
