how to convert xls to xlsx

Question

I have some *.xls(excel 2003) files， and I want to convert those files into xlsx(excel 2007).

I use the uno python package, when I save the documents, I can set the

Answer 1

Simple solution

I required a simple solution to convert couple of xlx to xlsx format. There are plenty of answers here, but they are doing some "magic" that I do not completely understand.

A simple solution was given by chfw, but not quite complete.

Install dependencies

Use pip to install

pip install pyexcel-cli pyexcel-xls pyexcel-xlsx

Execute

All the styling and macros will be gone, but the information is intact.

For single file

pyexcel transcode your-file-in.xls your-new-file-out.xlsx

For all files in the folder, one liner

for file in *.xls; do; echo "Transcoding $file"; pyexcel transcode "$file" "${file}x"; done;

Answer 2

Here is my solution, without considering fonts, charts and images:

$ pip install pyexcel pyexcel-xls pyexcel-xlsx

Then do this::

import pyexcel as p

p.save_book_as(file_name='your-file-in.xls',
               dest_file_name='your-new-file-out.xlsx')

If you do not need a program, you could install one additinal package pyexcel-cli::

$ pip install pyexcel-cli
$ pyexcel transcode your-file-in.xls your-new-file-out.xlsx

The transcoding procedure above uses xlrd and openpyxl.

Answer 3

The answer by Ray helped me a lot, but for those who search a simple way to convert all the sheets from a xls to a xlsx, I made this Gist:

import xlrd
from openpyxl.workbook import Workbook as openpyxlWorkbook

# content is a string containing the file. For example the result of an http.request(url).
# You can also use a filepath by calling "xlrd.open_workbook(filepath)".

xlsBook = xlrd.open_workbook(file_contents=content)
workbook = openpyxlWorkbook()

for i in xrange(0, xlsBook.nsheets):
    xlsSheet = xlsBook.sheet_by_index(i)
    sheet = workbook.active if i == 0 else workbook.create_sheet()
    sheet.title = xlsSheet.name

    for row in xrange(0, xlsSheet.nrows):
        for col in xrange(0, xlsSheet.ncols):
            sheet.cell(row=row, column=col).value = xlsSheet.cell_value(row, col)

# The new xlsx file is in "workbook", without iterators (iter_rows).
# For iteration, use "for row in worksheet.rows:".
# For range iteration, use "for row in worksheet.range("{}:{}".format(startCell, endCell)):".

You can find the xlrd lib here and the openpyxl here (you must download xlrd in your project for Google App Engine for example).

Answer 4

The Answer from Ray was clipping the first row and last column of the data. Here is my modified solution (for python3):

def open_xls_as_xlsx(filename):
# first open using xlrd
book = xlrd.open_workbook(filename)
index = 0
nrows, ncols = 0, 0
while nrows * ncols == 0:
    sheet = book.sheet_by_index(index)
    nrows = sheet.nrows+1   #bm added +1
    ncols = sheet.ncols+1   #bm added +1
    index += 1

# prepare a xlsx sheet
book1 = Workbook()
sheet1 = book1.get_active_sheet()

for row in range(1, nrows):
    for col in range(1, ncols):
        sheet1.cell(row=row, column=col).value = sheet.cell_value(row-1, col-1) #bm added -1's

return book1

Answer 5

I'm improve performance for @Jackypengyu method.

• XLSX: working per row, not per cell (http://openpyxl.readthedocs.io/en/default/api/openpyxl.worksheet.worksheet.html#openpyxl.worksheet.worksheet.Worksheet.append)
• XLS: read whole row excluding empty tail, see ragged_rows=True (http://xlrd.readthedocs.io/en/latest/api.html#xlrd.sheet.Sheet.row_slice)

Merged cells will be converted too.

Answer 6

Try using win32com application. Install it in your machine.

import sys, os
import win32com.client
directory = 'C:\\Users\\folder\\'
for file in os.listdir(directory):
    dot = file.find('.')
    end = file[dot:]
    OutFile =file[0:dot] + ".xlsx"
    App = win32com.client.Dispatch("Excel.Application")
    App.Visible = True
    workbook= App.Workbooks.Open(file)
    workbook.ActiveSheet.SaveAs(OutFile, 51)   #51 is for xlsx 
    workbook.Close(SaveChanges=True)
    App.Quit()

Thank you.
