　　2, openpyxl create a xlsx file

# ! / Usr / bin / env Python 
# - * - Coding: UTF-8 - * - 
Import json
 from openpyxl Import Workbook 


# create a xlsx file 
DEF create_xlsx (DATA_LIST): 
    wb = Workbook ()   # Create a workbook 
    ws = wb .active   # activate the worksheet 
    ws1 = wb.create_sheet ( " MySheet " )   # create mysheet table 
    ws.title = " New the Title "   # indicated that the Title was changed to New 
    ws.sheet_properties.tabColor = " 1072BA "   # color

    for row_index, Row in the enumerate (DATA_LIST): 
        thead_list = DATA_LIST [0]   # [ 'ID', 'name', 'Sex', 'Age'] 
        row_index + = 1   # Excel rows starting from 1 calculated 

        for the Column_Index, thead in the enumerate (thead_list): 
            the Column_Index +. 1 =   # Excel rows is calculated from the start. 1 

            IF row_index. 1 ==:             # Step: filling a first data row, the first table (ID Sex Age name) 
                D = ws.cell (Row =. 1, column = the Column_Index, value = thead)
             the else :                          # Step: New table data
                d = ws.cell(row=row_index, column=column_index, value=row[column_index-1])
        wb.save('test.xlsx')#保存


data_list = [
    ['id','name','sex','age'],
    ['1','张三','男','18'],
    ['2', ' John Doe ' , ' male ' , ' 19 ' ], 
    [ ' 3 ' , ' king five ' , ' female ' , ' 20 ' ], 
] 
create_xlsx (DATA_LIST)

　　3, openpyxl modify the value of the tenth column

# ! / Usr / bin / Python the env 
# - * - Coding: UTF-. 8 - * - 
Import JSON
 from openpyxl Import load_workbook 


# The values in the table to modify the tenth row uniform 'new new Val' 
DEF change_xlsx (file_home): 
    WB load_workbook = (filename = file_home) 
    sheet_ranges = WB [ ' Sheet1 ' ] 
    WS = WB [ ' Sheet1 ' ] 
    rows = ws.rows     # obtain forms all rows and columns, both of which are iterative 
    for row, line in the enumerate ( rows):
         IF Row =! 0:
            row += 1
            ws.cell(row=row, column=10).value = 'new val'
    wb.save('f5.xlsx')


change_xlsx('dd.xlsx')

openpyxl modify the value of the fourth column

# ! / Usr / bin / Python the env 
# - * - Coding: UTF-. 8 - * - 
from openpyxl Import load_workbook 

file_home = ' f5.xlsx ' 
WB = load_workbook (filename = file_home) 
sheet_ranges = WB [ ' Sheet1 ' ] 
WS = WB [ ' Sheet1 ' ] 

# of the second row, second column value is modified to 'modified value' 
ws.cell (row = 2, column = 2) .Value = ' modified value ' 
wb.save ( ' f6.xlsx ' )

openpyxl modify the basic usage

　　4, adding new content file xlsx later (in the order of data insertion)

# ! / Usr / bin / the env Python 
# - * - Coding: UTF-. 8 - * - 
Import JSON, SYS
 from openpyxl Import load_workbook 


# in xlsx file add the new data is inserted into xlsx file corresponding to the location in order 
DEF append_xlsx (file_home, DATA_LIST):
     '' ' 
    : param file_home: XLSX file path 
    : param data_list: inserting the data 
    ' '' 
    WB = load_workbook (filename = file_home) 
    sheet_ranges = WB [ ' Sheet1 ' ] 
    WS = WB [ ' Sheet1 ' ]
     Print DATA_LIST 
    ws.append (DATA_LIST)
    wb.save ( ' f7.xlsx ' ) 


DATA_LIST = [ ' mailbox ' , '' , ' phone number ' , ' Sex ' ] 
append_xlsx ( ' dd.xlsx ' , DATA_LIST)
