I'm working on a script that modifies an existing excel document and I need to have the ability to insert a column between two other columns like the VBA macro command .EntireColumn.Insert.
Is there any method with openpyxl to insert a column like this?
If not, any advice on writing one?
Here is an example of a much much faster way:
import openpyxl
wb = openpyxl.load_workbook(filename)
sheet = wb.worksheets[0]
# this statement inserts a column before column 2
sheet.insert_cols(2)
wb.save("filename.xlsx")
Haven't found anything like .EntireColumn.Insert in openpyxl.
First thought coming into my mind is to insert column manually by modifying _cells on a worksheet. I don't think it's the best way to insert column but it works:
from openpyxl.workbook import Workbook
from openpyxl.cell import get_column_letter, Cell, column_index_from_string, coordinate_from_string
wb = Workbook()
dest_filename = r'empty_book.xlsx'
ws = wb.worksheets[0]
ws.title = "range names"
# inserting sample data
for col_idx in xrange(1, 10):
col = get_column_letter(col_idx)
for row in xrange(1, 10):
ws.cell('%s%s' % (col, row)).value = '%s%s' % (col, row)
# inserting column between 4 and 5
column_index = 5
new_cells = {}
ws.column_dimensions = {}
for coordinate, cell in ws._cells.iteritems():
column_letter, row = coordinate_from_string(coordinate)
column = column_index_from_string(column_letter)
# shifting columns
if column >= column_index:
column += 1
column_letter = get_column_letter(column)
coordinate = '%s%s' % (column_letter, row)
# it's important to create new Cell object
new_cells[coordinate] = Cell(ws, column_letter, row, cell.value)
ws._cells = new_cells
wb.save(filename=dest_filename)
I understand that this solution is very ugly but I hope it'll help you to think in a right direction.

I'm trying to copy specific rows from Workbook 1 and append it to the existing data in Workbook 2.
Copy the highlighed rows from
Workbook 1,
and append them in Workbook 2 below 'March'
So far I succeeded to copy and paste the range, but there are two problems:
1.Cells are a shifted
2.The percentage(formula) is missing, leaving only numeric values.
See Result here
import openpyxl as xl
source = r"C:\Users\Desktop\Test_project_20200401.xlsx"
wbs = xl.load_workbook(source)
wbs_sheet = wbs["P2"] #selecting the sheet
destination = r"C:\Users\Desktop\Try999.xlsx"
wbd = xl.load_workbook(destination)
wbd_sheet = wbd["A3"] #select the sheet
row_data = 0
for row in wbs_sheet.iter_rows():
for cell in row:
if cell.value == "Yes":
row_data += cell.row
for row in wbs_sheet.iter_rows(min_row=row_data, min_col = 1, max_col=250, max_row = row_data+1):
wbd_sheet.append((cell.value for cell in row))
wbd.save(destination)
Does anyone have any idea on how can I solve this?
Any feedback/solution would help!
Thanks!
I think min_col should = 0
Range("A1").Formula (in VBA) gets the formula.
Range("A1").Value (in VBA) gets the value.
So try using .formula in Python
(thanks to: Get back a formula from a cell - VBA ... if this works)
Just want to add my own solution in here.
What I did, was to iterate through the columns and apply "cell.number_format = '0%', which converts your cell value to percentage.
for col in ws.iter_cols(min_row=1, min_col=2, max_row=250, max_col=250):
for cell in col:
cell.number_format = '0%'

Question: Can someone please let me know how I can achieve the following task:
I've defined the column, but i need a specific value to go into each cell within that column.
Also, if column 6 only has x amount of rows, then i want column 7 to also have only x amount of rows with the values pasted in it.
This is the code i've tried.
import openpyxl
wb = openpyxl.load_workbook(filename=r'C:\Users\.spyder-py3\data\BMA.xlsx')
ws = wb.worksheets[0]
for row in ws.iter_rows('G{}:G{}'.format(ws.min_row,ws.max_row)):
for cell in row:
ws.cell(row=cell, column=7).value = 'BMA'
wb.save(r'C:\Users\.spyder-py3\data\BMA.csv')
wb.close()
I figured out most of the issue by looking at this answer:
https://stackoverflow.com/a/15004956/9649146
This is the code i end up with:
import openpyxl
wb = openpyxl.load_workbook(filename=r'C:\Users\.spyder-py3\data\AAXN.xlsx')
ws = wb.worksheets[0]
r = 2
for row in ws.iter_rows('G{}:G{}'.format(ws.min_row,ws.max_row)):
for cell in row:
ws.cell(row=r, column=7).value = 'AAXN'
r += 1
wb.save(r'C:\Users\.spyder-py3\data\AAXN.csv')
wb.close()
Or, you can do something like this:
for row in filesheet.iter_rows(min_row=2, max_row=file_sheet.max_row):
filesheet.cell(row=row[0].row, column=7).value = 'my value'
First: I just started with python. And spefically with openpyxl.
So I went ahead and tried this code out:
from openpyxl import load_workbook
wb = load_workbook('E:/Python36/Test/sample.xlsx')
ws = wb['Sheet']
#get all values, without knowing the row and column dimension - possible?
myRange = []
for row in ws.iter_rows(min_row=9, max_row=13, min_col=9, max_col=11):
rowList = []
for cell in row:
rowList.append(cell.value)
myRange.append(rowList)
targetRange = ws.iter_rows()
#paste all values, in specific range on new sheet or new wb? how?
wb.create_sheet('Sheet2')
ws = wb['Sheet2']
for i, j in zip(targetRange, myRange):
for a, b in zip(i, j):
a.value = b
wb.save('E:/Python36/Test/exa.xlsx')
And now I'm stuck :)
My questions are:
1) I can't figure out how to get all cell values on a sheet, without knowing the row and column dimensions on fore hand - is this possible?
2) I want to paste all the found values (range) in a (other) specific workbook sheet beginning in row 4 column 4.
TiA!
I'm trying to build a report generator which reads excel sheets and returns rows which contain values. I built a version which works as I require but only works for csv this is only my 1st code-mash-together, but it worked. I now would like to include conditional formatting as well (highlight certain cells values eg. if <65 format red) and so that required that I rewrite with xlsx sheets rather than csv.
Below is my attempt at getting this to work...
I can find the values and return the row, but on the second run through it returns an error
AttributeError: 'Worksheet' object has no attribute 'cell_value'
Which is surprising because it worked just previously and stepping through the code retuns the values I want.... I have tried changing it to .value, but returns:
AttributeError: 'function' object has no attribute 'value'
Help, I have no idea what I'm doing now. If it doens't make any sense i'm happy to post my original code for the csv to 'explain'
Thanks

I have no experience with xlsxwriter, xlrd or xlwt. As this is your "1st code-mash-together" I figured I would offer an alternative using openpyxl.
I do not have your data, so testing is a little difficult, but any syntax errors could be fixed. Please let me know if this does not run and I will help fix if required.
I am assuming your output is to a seperate file(report.xlsx here) and a tab for each workbook checked(each tab named for source book name).
import openpyxl
from openpyxl import *
from openpyxl.utils import get_column_letter
interestingValues = ['CP','LNA', 'LastName']
report = Workbook()
dest_filename = 'report.xlsx'
# open original excelbook and access first sheet
for excelDocs in os.listdir('.'):
if not excelDocs.endswith('.xlsx'):
continue # skip non-xlsx files
workbook = load_workbook(excelDocs)
sheet = workbook.active
workingReportSheet = report.create_sheet(str(excelDocs.split('.')[0]))
i = 0
for row in range(1,sheet.max_row):
for col in range(sheet.max_column):
columnLetter = get_column_letter(col +1)
if str(sheet['%s%s' % (columnLetter,row)].value) in interestingValues:
i += 1
data = [sheet['%s%s' % (str(get_column_letter(col)),i)].value for col in range(1,sheet.max_column +1)]
for index, value in enumerate(data):
workingReportSheet['%s%s' % (str(get_column_letter(index+1)),i)].value = value
report.save(filename = dest_filename)
Reading your code again, it may be that you are discarding your output.
Try the below.
import xlsxwriter
import xlrd
import os
import xlwt
#Create output sheet
outputworkbook = xlsxwriter.Workbook()
# open original excelbook and access first sheet
for excelDocs in os.listdir('.'):
if not excelDocs.endswith('.xlsx'):
continue # skip non-xlsx files
workbook = xlrd.open_workbook(excelDocs)
sheet = workbook.sheet_by_index(0)
cellslist = []
i = 0
outputsheet = outputworkbook.add_worksheet('excelDocs')
for row in range(sheet.nrows):
for col in range(sheet.ncols):
if sheet.cell_value(row, col) == 'CP' or sheet.cell_value(row, col) == 'LNA' or sheet.cell_value(row, col) == 'Last Name':
i = i + 1
data = [sheet.cell_value(0, col) for col in range(sheet.ncols)]
for index, value in enumerate(data):
outputsheet.write(i, index, value)
I want to transfer my data which is in 'Sheet1' into worksheet 'Sheet2'in the same workbook, using python.I have written the script below, but facing an 'IndexError: list index out of range'. I know this is not the best way to go about it. I will appreciate if anyone can guide me with a more efficient way to go about it. I am sharing the Snapshot of excel file below
Can I directly enter 'Sheet1' cell value ---> 'Sheet2' cell value rather than doing 'Sheet1' cell value ---> List---->'Sheet2' cell value?
import openpyxl
wb = openpyxl.load_workbook('C:\Users\laban\Desktop\Par-emails1.xlsx')
type(wb)
wb.get_sheet_names()
sheet = wb.get_sheet_by_name('Sheet1')
type(sheet)
anotherSheet = wb.active
sheet1 = wb.get_sheet_by_name('Sheet2')
type(sheet1)
par=[sheet.cell(row= col, column=1).value for col in range(1, 2450)]
email_no=[sheet.cell(row= col, column=2).value for col in range(1, 2450)]
Domain=[sheet.cell(row= col, column=3).value for col in range(1, 2450)]
email=[sheet.cell(row= col, column=4).value for col in range(1, 2450)]
for x in range(0,2450):
if email_no[x]<9:
sheet1.cell(row= x+1, column=1).value=par[x]
sheet1.cell(row= x+1, column=2).value=email_no[x]
sheet1.cell(row= x+1, column=3).value=Domain[x]
sheet1.cell(row= x+1, column=4).value=email[x]
wb.save('C:\Users\laban\Desktop\Par-emails1.xlsx')
You can use:
wb = openpyxl.load_workbook('C:/Users/laban/Desktop/Par-emails1.xlsx')
sheet1 = wb.get_sheet_by_name('Sheet1')
sheet2 = wb.get_sheet_by_name('Sheet2')
for i,row in enumerate(sheet1.iter_rows()):
for j,col in enumerate(row):
sheet2.cell(row=i+1,column=j+1).value = col.value
Apparently in 2.4 you can do this with one command: Copy whole worksheet with openpyxl
Obviously this is very simplified version from what I am currently using.
Here is a code snippet to copy data from sheet1 to sheet2 without any formatting.
You dont need to specify max rows , max columns as you can get it using
sheet.max_row and sheet.max_columns methods.
from openpyxl.cell import Cell
max_row = sheet1.max_row #Get max row of first sheet
max_col = sheet1.max_column #Get max column of first sheet
for row_num in range(1,max_row + 1): #Iterate through rows
for col_num in range(1, max_col + 1): #Iterate through columns
_cell1 = sheet1.cell(row=row_num, column=col_num)
_cell2 = sheet2.cell(row=row_num, column=col_num)
_cell2.value = _cell1.value
Added extra variables for understanding. You can compact at your end.
bernie probably has the best answer here (Copy whole worksheet) but your index error might be coming from:
par=[sheet.cell(row= col, column=1).value for col in range(1, 2450)]
being 1 cell shorter than:
for x in range(0,2450):
def excel_op():
filename='D://Python//excelread.xlsx'
sheet_name='Sheet1'
book = xlrd.open_workbook(str(filename))
sheet = book.sheet_by_name(sheet_name)
workbook = xlsxwriter.Workbook('excelwrite.xlsx')
worksheet = workbook.add_worksheet()
row_count = int(sheet.nrows)
col_count = int(sheet.ncols)
for row in range(0, int(row_count)):
for col in range(0, int(col_count)):
worksheet.write(row,col,str(sheet.cell(row, col).value))
workbook.close()
del book
shutil.copy("Source.xlsx", "target.xlsx")
