读取excel生成相应的json文件的脚本

excel的格式如下

 python代码如下，这里最难的就是合并单元格的处理

import xlrd
import json

excel_obj = xlrd.open_workbook("test.xlsx")


sheet_name = excel_obj.sheet_names()[0]

sheet_obj = excel_obj.sheet_by_index(0)

hadoop_dict = {
    "services": [
    "AMBARI_METRICS",
    "HBASE",
    "HDFS",
    "HIVE",
    "KAFKA",
    "MAPREDUCE2",
    "PIG",
    "SLIDER",
    "SMARTSENSE",
    "SPARK2",
    "STORM",
    "TEZ",
    "YARN",
    "ZOOKEEPER"
  ],
    "pm_group" :[],
    "host_groups":[]
}


host = {}
vm = {}
# components_list = []


r_num = sheet_obj.nrows
c_num = sheet_obj.ncols



merge_cell_list = sheet_obj.merged_cells

# for i in range(r_num):
#     if sheet_obj.cell_value(i,c_num-1):
#         components_list.append(sheet_obj.cell_value(i,c_num-1))

# 获取最后一列的所有数据


for i in merge_cell_list:
    if i[2] == 0:
        host[sheet_obj.cell_value(i[0],i[2])] = [i[0],i[1],i[2],i[3]]

# 存放所有合并的单元格


for k,v in host.items():
    host_dict = {}
    print(sheet_obj.cell_value(v[0],1),sheet_obj.cell_value(v[0],2),sep="---->")
    # 获取主机的ip地址
    pm_ip = sheet_obj.cell_value(v[0],2)
    print(pm_ip,"物理机地址")


    print(sheet_obj.cell_value(v[0] + 1,1),sheet_obj.cell_value(v[0] + 1,2),sep="---->")
    # 获取主机的主机名
    pm_name = sheet_obj.cell_value(v[0] + 1,2)

    host_dict["ip"] = pm_ip
    host_dict["hostname"] = pm_name
    host_dict["vms"] = []


    for vms_cell in merge_cell_list:
        vm_dict = {}
        vm_components_dict = {}
        if vms_cell[1] <= host[k][1] and vms_cell[2] == 2 and vms_cell[0] > host[k][0] + 1:
            print(sheet_obj.cell_value(vms_cell[0],2))
            # 获取虚拟机的名称
            print(sheet_obj.cell_value(vms_cell[0],vms_cell[2] + 1))
            # 获取虚拟机的ip的k

            print(sheet_obj.cell_value(vms_cell[0],vms_cell[2] + 2))
            # 获取虚拟机的ip地址
            vm_ip = sheet_obj.cell_value(vms_cell[0], vms_cell[2] + 2)



            print(sheet_obj.cell_value(vms_cell[0] + 1, vms_cell[2] + 1))
            # 获取虚拟机的虚拟机名称的k


            print(sheet_obj.cell_value(vms_cell[0] + 1, vms_cell[2] + 2))
            # 获取虚拟机的名字的值

            vm_name = sheet_obj.cell_value(vms_cell[0] + 1, vms_cell[2] + 2)


            vm_name = sheet_obj.cell_value(vms_cell[0] + 1, vms_cell[2] + 2)
            vm_dict = {
                "hostname":vm_name,
            }

            vm_components_dict["ip"] = vm_ip
            vm_components_dict["hostname"] = vm_name
            vm_components_dict["components"] = []


            host_dict["vms"].append(vm_dict)

            vmcomponents_location_start = vms_cell[0] + 2
            vmcomponents_location_end = vms_cell[1]
            # print(vmcomponents_location_start,vmcomponents_location_end,"我是大傻逼")
            vm_components_info_list = []
            for i in range(vmcomponents_location_start,vmcomponents_location_end):
                temp_components = sheet_obj.cell_value(i,c_num-1)
                vm_components_info_list.append(temp_components)

            for component  in vm_components_info_list:
                temp_dict = {}
                temp_dict["name"] = component
                vm_components_dict["components"].append(temp_dict)

            hadoop_dict["host_groups"].append(vm_components_dict)

            # 获取每个虚拟机的components信息
    hadoop_dict["pm_group"].append(host_dict)


import json
file_name = "journalnode_".upper() + "test_journalnode_case_1" + "." + "json"
my_file_obj = open(file_name,"w")

json.dump(hadoop_dict,my_file_obj,indent=4)
my_file_obj.close()

　　

最后按照要求生成制定格式的json文件
