python菜鸟学习： 13. excel文件编辑openpyxl使用

#1. xls文件转换成xlsx文件，需要使用到 win32com

from win32com import client as wc

filepath = "D:\\python\\liyuzhuopan\\s14\\20220531"

# xls 转化成xlsx
def convert_Xsl_To_xlsx(filepath, filename, new_filename):
    if new_filename.split(".")[1] == "xlsx":
        e = wc.Dispatch('Excel.application')
        pro = e.Workbooks.Open(filepath + "\\\\" + filename)  #
        # 另存为新的文件
        new_excel_path = filepath + "\\" + new_filename
        print(new_excel_path)
        pro.SaveAs(new_excel_path, FileFormat=51) #FileFormat=51为xlsx文件格式

        pro.Close()
        e.Application.Quit()
        # 格式转换
        return "转换成功{_filename}".format(_filename=new_filename)
    else:
        print("请输入新文件名称为.xlsx结尾")
        return "请输入新文件名称为.xlsx结尾"

# xlsx转化成xls
# convert_Xsl_To_xlsx(filepath, "merge_setup20210807.xls", "merge_setup20210807.xlsx")

#2. xlsx文件转换成xls文件，需要使用到 win32com

def convert_xlsx_To_xls(filepath, filename, new_filename):
    if new_filename.split(".")[1] == "xls":
        # 格式转换
        e = wc.Dispatch('Excel.application')
        pro = e.Workbooks.Open(filepath + "\\\\" + filename)  #
        # 另存为新的文件
        new_excel_path = filepath + "\\" +  new_filename
        pro.SaveAs(new_excel_path, FileFormat=56) #FileFormat=56为xls文件格式

        pro.Close()
        e.Application.Quit()
    else:
        print("请输入新文件名称为.xls结尾")
        return "请输入新文件名称为.xls结尾"

# convert_xlsx_To_xls(filepath, "merge_setup20210807_new.xlsx", "merge_setup20210807.xls")

#3.读取excel文件内容 需要用到 openyxl load_workbook

from openpyxl import  load_workbook, styles

def readExcel(filepath, filename):
    facilityDict = {}
    # print(filepath + filename)
    readfile = load_workbook(filepath + "\\\\" + filename)
    # 获取excel中的页签
    # print(readfile.sheetnames)
    for i in readfile:
        # 读取excel中页签的值i.title
        if i.title == "facility":
            # 循环读取sheet里面的值，存放在字典表中
            for index1 in range(2, i.max_row + 1):
                key1 = str(readfile[i.title].cell(index1, 1).value)
                value1 = str(readfile[i.title].cell(index1, 12).value)
                value2 = str(readfile[i.title].cell(index1, 13).value)
                facilityDict[key1] = value1 + "," + value2
        elif i.title == "config":
            for index2 in range(2, i.max_row + 1):
                key2 = str(readfile[i.title].cell(index2, 4).value)
                value3 = str(readfile[i.title].cell(index2, 6).value)
                # print(key2, value3)
                facilityDict[key2] = value3
        else:
            pass
    readfile.close()
    return facilityDict

# print(readExcel(filepath, "merge_setup20210807_new.xlsx"))

4. 写入excel文件 openyxl load_workbook

def wirteExcel(filepath, new_filename, dict1={}):
    wirteFlie = load_workbook(filepath + "\\\\" + new_filename)
    for i in wirteFlie:
        if i.title == "facility":
            for index1 in range(2, i.max_row + 1):
                # 如果文件的第一行存在字典中则切割后赋值给excel的单元格
                if wirteFlie[i.title].cell(index1, 1).value in dict1.keys():
                    value1 = dict1[wirteFlie[i.title].cell(index1, 1).value]
                    if str(value1).split(",")[1] != "None":
                        # print(value1)
                        column12 = str(value1).split(",")[0]
                        column13 = str(value1).split(",")[1]
                        wirteFlie[i.title].cell(index1, 12, column12)
                        wirteFlie[i.title].cell(index1, 13, column13)
                    else:
                        pass
                else:
                    # 如果不存在字典中，则将该单元格变成黄色
                    wirteFlie[i.title].cell(row=index1, column=12).fill = yellow_fill
                    wirteFlie[i.title].cell(row=index1, column=13).fill = yellow_fill
                    # print(i.title + str(index1) + "set yellow")
        elif i.title == "config":
            for index2 in range(2, i.max_row + 1):
                # print(wirteFlie[i.title].cell(index2, 4).value)
                if wirteFlie[i.title].cell(index2, 4).value in dict1.keys():
                    value3 = dict1[wirteFlie[i.title].cell(index2, 4).value]
                    # print(value3)
                    if value3 != "None":
                        # print(value1)
                        wirteFlie[i.title].cell(index2, 6, value3)
                    else:
                        pass
                else:
                    # 如果不存在字典中，则将该单元格变成黄色
                    wirteFlie[i.title].cell(row=index2, column=6).fill = yellow_fill
                    # print(i.title + str(index2) + "set yellow")
        else:
            pass
    wirteFlie.save(new_filename)
    wirteFlie.close()

# wirteExcel(filepath, "merge_setup20210807.xlsx", dict1)
