python处理excel有xlwt，openpyxl等，而xlwt只支持excel2003，也就是最多有256列，而openpyxl则支持excel2007以上，最多65536列。下面是两个的程序。 xlwt为

import json  import xlwt  def readFromJson(file):      with open(file, 'r', encoding='utf8') as fr:          jsonData = json.load(fr)      return jsonData    def writeToExcel(file):      json = readFromJson(file)      excel = xlwt.Workbook()      sheet1 = excel.add_sheet('sheet1', cell_overwrite_ok=True)      sheet2 = excel.add_sheet('sheet2', cell_overwrite_ok=True)      length = len(json)      i = 0      while i < length:          eachLine = json[i]          questions = eachLine['questions']          answer = eachLine['answer']          questionSize = len(questions)          if (questionSize > 256):              print(i + 1, questionSize)          j = 0          while j < questionSize:              ques = questions[j]              eachQues = ques['question']              if j < 256:                  sheet1.write(i, j, eachQues)              if j == 0:                  sheet2.write(i, 0, eachQues)              j = j + 1          sheet2.write(i, 1, answer)          i = i + 1      excel.save('doc/answer.xls')    if __name__ == '__main__':      writeToExcel('doc/kb.json')

openpyxl为

import openpyxl  import json  def readFromJson(file):      with open(file, 'r', encoding='utf8') as fr:          jsonData = json.load(fr)      return jsonData    def writeToExcel(file):      json = readFromJson(file)      excel = openpyxl.Workbook()      sheet1 = excel.create_sheet('sheet1', index=0)      sheet2 = excel.create_sheet('sheet2', index=0)      length = len(json)      i = 0      while i < length:          eachLine = json[i]          questions = eachLine['questions']          answer = eachLine['answer']          questionSize = len(questions)          j = 0          while j < questionSize:              ques = questions[j]              eachQues = ques['question']              sheet1.cell(row=i + 1, column=j + 1, value=eachQues)              if j == 0:                  sheet2.cell(row=i + 1, column=1, value=eachQues)              j = j + 1          sheet2.cell(row=i + 1, column=2, value=answer)          i = i + 1      excel.save('doc/answer.xlsx')    if __name__ == '__main__':      writeToExcel('doc/kb.json')

其核心在于读取json的方法和写入excel的方法。
