How to write/update data into cells of existing XLSX workbook using xlsxwriter in python

问题

I am able to write into new xlsx workbook using

import xlsxwriter  
def write_column(csvlist):
    workbook = xlsxwriter.Workbook("filename.xlsx",{'strings_to_numbers': True})
    worksheet = workbook.add_worksheet()
    row = 0
    col = 0
    for i in csvlist:
        worksheet.write(col,row, i)
        col += 1

    workbook.close()

but couldn't find the way to write in an existing workbook. Please help me to write/update cells in existing workbook using xlswriter or any alternative.

回答1:

Quote from xlsxwriter module documentation:

This module cannot be used to modify or write to an existing Excel XLSX file.

If you want to modify existing xlsx workbook, consider using openpyxl module.

回答2:

you can use this code to open (test.xlsx) file and modify A1 cell and then save it with a new name

import openpyxl
xfile = openpyxl.load_workbook('test.xlsx')

sheet = xfile.get_sheet_by_name('Sheet1')
sheet['A1'] = 'hello world'
xfile.save('text2.xlsx')

Note that openpyxl does not have a large toolbox for manipulating and editing images. Xlsxwriter has methods for images, but on the other hand cannot import existing worksheets...

I have found that this works for rows... I'm sure there's a way to do it for columns...

import openpyxl

oxl = openpyxl.load_workbook('File Loction Here')
xl = oxl.['SheetName']

x=0
col = "A"
row = x

while (row <= 100):
    y = str(row)
    cell = col + row
    xl[cell] = x
    row = row + 1
    x = x + 1

If you have issue with writing into an existing xls file because it is already created you need to put checking part like below:

PATH='filename.xlsx'
if os.path.isfile(PATH):
    print "File exists and will be overwrite NOW"
else:
    print "The file is missing, new one is created"

... and here part with the data you want to add
