1. Create / Read excel file
Creating excel
from openpyxl import Workbook wb = Workbook()
Read excel
from openpyxl import load_workbook
wb = load_workbook('1.xlsx')
Save excel
wb.save('filename.xlsx')
2.sheet form action
Gets sheet
# Way to list all sheet returns excel file name (-> list [str, str ..]) wb.sheetnames wb.get_sheet_names ()
Select the sheet objects
# Select The sheet name WS WB = [ 'Sheet1'] WS = wb.get_sheet_by_name ( 'Sheet1') # the currently displayed, the active sheet WS = wb.active WS = wb.get_active_sheet ()
Create a new sheet
# Default inserted in the last WS = wb.create_sheet ( "NewSheet") # inserted into the beginning position (counted from 0) WS = wb.create_sheet ( "NewSheet", 0)
Copy a sheet objects
source = wb.active target = wb.copy_worksheet(source)
Delete sheet
wb.remove(sheetobject) del wb['sheet'] #sheetname
Common property sheet
#sheet name
sheet.title
# maximum row and maximum column
sheet.max_row
sheet.max_column
# ranks generator
sheet.rows # row generator, which is a target cell for each row by a tuple package.
sheet.columns # column generator, which is a target cell for each column, a tuple from the package.
May be used list (sheet.rows) [0] .value the like to obtain data, or
for in sheet.rows Row:
for in Row Cell:
Print (Cell.Value)
to traverse value, or the value generator only sheet.values traversal value
Other operations of the sheet
# Insert rows, insert before the line 7 ws.insert_rows (7) # insert a column, insert column before 7 ws.insert_cols (7) # delete ranks ws.delete_rows (7) ws.delete_cols (7) # can be deleted a plurality ws.delete_cols (6, 3)
3. The cell object
Cell object selected cell
# The Name Access column cell row 1 subject WS = A1 [ 'A1'] #A A2 = WS [ 'A2'] # or lowercase #cell access method b2 = ws.cell (row = 2, column = 2) ws.cell = B3 (3,2-) # returns the list from cell B3 = list (ws.rows) [2] [. 1] B3 = list (ws.columns) [. 1] [2]
Cell Properties
# Returns the column cell.column # returns rows cell.row # Return Value cell.value Note: If the cell is the use of the formula, the value is a value instead of calculating equation # return unit formatting attributes cell.number_format default General format # cell styles cell.font
Change the value in cell
# Direct assignment WS [ 'A2'] = 222 WS [ 'A2'] = 'AAA' WS [ 'B2'] = '= the SUM (A1: A17)' using Equation # #value property assignment cell.value = 222 or ws.cell (1,2, value = 222)
Move cells
ws.move_range ( "D4: F10", rows = -1, cols = 2) represents cells D4: F10 moves up one line, the right two columns. Cell will overwrite any existing cells. (The latest version of this method will use pip list to see whether the latest version) ws.move_range ( "G4: H10", rows = 1, cols = 1, Translate = True) move automatically included in the conversion formula
Combined with the split cells
# Merged cell, the upper left corner to write data or read data ws.merge_cells ( 'A2: D2 of') # split cells ws.unmerge_cells ( 'A2: D2')
