# Create the Workbook, and creates a default table empty, entitled: Sheet 
WB = the Workbook ()
 # Get Default Sheet 
WS1 = wb.active
 # Set Sheet Name 
ws1.title = ' Sheet1 ' 
# Write Single cell 
WS1 [ ' A1 ' ] = ' title bar. 1 ' 
WS1 [ ' Bl ' ] = ' title bar 2 ' 
# written in a plurality of cells (written from the next line of data) 
ws1.append ([ ' John Doe ' , 80 ]) 
ws1.append ([ ' John Doe' , 90 ]) 

# create a new sheet, you can specify the name 
ws2 = wb.create_sheet ( ' Sheet2 ' ) 

# copy Sheet1, the new name for the sheet Copy Sheet1 
ws3 = wb.copy_worksheet (wb [ ' Sheet1 ' ]) 

# print all table name 
Print (wb.sheetnames) 

# save 
wb.save ( ' 1.xlsx ' )

The results Excel reads as follows:

Third, read Excel data

1.xlsx read data created above

from openpyxl Import the Workbook
 from openpyxl Import load_workbook 

WB = load_workbook ( ' 1.xlsx ' )
 # speculation format type 
wb.guess_types = True    
WS1 = wb.active 

Print ( " number of rows " , ws1.max_row)
 Print ( " total number of columns ' , ws1.max_column) 

Print ( ' --- value acquiring single cell --- ' )
 Print (WS1 [ ' A1 ' ] .Value)
 Print(WS1 [1] [0] .Value) # where A1 is the value from the row index 1, index column counting from 0 

Print ( ' --- get values for all the single --- ' )
 for Cell in WS1 [ ' a ' ]:
     Print (Cell.Value) 

Print ( ' --- get the value of a plurality of columns (by slicing) --- ' )
 # If the range is larger than the actual, real as AB only two, designated a: B, the acquisition result returned None, and C is the column and later .columns .rows acquired 
for column in WS1 [ ' A: B ' ]:
     for Cell in column:        
         Print (Cell.Value) 

Print ( '--- get the value of all the columns --- ' )
 for column in ws1.columns: # can also be used ws1.iter_cols () 
    for the Cell in column:
         Print (Cell.Value) 

Print ( ' --- get the value of a row --- ' )
 for Cell in WS1 [. 1 ]:
     Print (Cell.Value) 

Print ( ' --- obtain the value of a plurality of rows (by slicing) --- ' )
 for row in WS1 [. 1: 2 ]:
     for the Cell in Row:
         Print (Cell.Value)

Print ( ' --- get the value of all rows --- ' )
 for Row in ws1.rows: # can also be used ws1.iter_rows () 
    for the Cell in Row:
         Print (Cell.Value)
