在2个文件之间转换,需要注意一个文件的字符转码问题。
xlsx文件转csv文件
- 使用xlrd和csv模块来处理Excel文件和csv文件
import xlrd import csv def xlsx_to_csv(): workbook = xlrd.open_workbook('1.xlsx') table = workbook.sheet_by_index(0) with codecs.open('1.csv', 'w', encoding='utf-8') as f: write = csv.writer(f) for row_num in range(table.nrows): row_value = table.row_values(row_num) write.writerow(row_value) if __name__ == '__main__': xlsx_to_csv()
- 使用第三方库pandas将xlsx文件转csv文件
import pandas as pd def xlsx_to_csv_pd(): data_xls = pd.read_excel('1.xlsx', index_col=0) data_xls.to_csv('1.csv', encoding='utf-8') if __name__ == '__main__': xlsx_to_csv_pd()
csv文件转换成xlsx文件
- 使用xlwt和csv模块来处理Excel文件和csv文件
-
import csv import xlwt def csv_to_xlsx(): with open('1.csv', 'r', encoding='utf-8') as f: read = csv.reader(f) workbook = xlwt.Workbook() sheet = workbook.add_sheet('data') # 创建一个sheet表格 l = 0 for line in read: print(line) r = 0 for i in line: print(i) sheet.write(l, r, i) # 一个一个将单元格数据写入 r = r + 1 l = l + 1 workbook.save('1.xlsx') # 保存Excel if __name__ == '__main__': csv_to_xlsx()
- 使用pandas将csv文件转成xlsx文件
-
import pandas as pd def csv_to_xlsx_pd(): csv = pd.read_csv('1.csv', encoding='utf-8') csv.to_excel('1.xlsx', sheet_name='data') if __name__ == '__main__': csv_to_xlsx_pd()
