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

Answer 1

I tried @Jhon Anderson's solution, works well but got an "year is out of range" error when there are cells of time format like HH:mm:ss without date. There for I improved the algorithm again:

def xls_to_xlsx(*args, **kw):
"""
    open and convert an XLS file to openpyxl.workbook.Workbook
    ----------
    @param args: args for xlrd.open_workbook
    @param kw: kwargs for xlrd.open_workbook
    @return: openpyxl.workbook.Workbook对象
    """
    book_xls = xlrd.open_workbook(*args, formatting_info=True, ragged_rows=True, **kw)
    book_xlsx = openpyxl.workbook.Workbook()

    sheet_names = book_xls.sheet_names()
    for sheet_index in range(len(sheet_names)):
        sheet_xls = book_xls.sheet_by_name(sheet_names[sheet_index])
        if sheet_index == 0:
            sheet_xlsx = book_xlsx.active
            sheet_xlsx.title = sheet_names[sheet_index]
        else:
            sheet_xlsx = book_xlsx.create_sheet(title=sheet_names[sheet_index])
        for crange in sheet_xls.merged_cells:
            rlo, rhi, clo, chi = crange
            sheet_xlsx.merge_cells(start_row=rlo + 1, end_row=rhi,
            start_column=clo + 1, end_column=chi,)

        def _get_xlrd_cell_value(cell):
            value = cell.value
            if cell.ctype == xlrd.XL_CELL_DATE:
                datetime_tup = xlrd.xldate_as_tuple(value,0)    
                if datetime_tup[0:3] == (0, 0, 0):   # time format without date
                    value = datetime.time(*datetime_tup[3:])
                else:
                    value = datetime.datetime(*datetime_tup)
            return value

        for row in range(sheet_xls.nrows):
            sheet_xlsx.append((
                _get_xlrd_cell_value(cell)
                for cell in sheet_xls.row_slice(row, end_colx=sheet_xls.row_len(row))
            ))
    return book_xlsx

Then work perfect!

I've had to do this before. The main idea is to use the xlrd module to open and parse a xls file and write the content to a xlsx file using the openpyxl module.

Here's my code. Attention! It cannot handle complex xls files, you should add you own parsing logic if you are going to use it.

import xlrd
from openpyxl.workbook import Workbook
from openpyxl.reader.excel import load_workbook, InvalidFileException

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
        ncols = sheet.ncols
        index += 1

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

    for row in xrange(0, nrows):
        for col in xrange(0, ncols):
            sheet1.cell(row=row, column=col).value = sheet.cell_value(row, col)

    return book1

You need to have win32com installed on your machine. Here is my code:

import win32com.client as win32
fname = "full+path+to+xls_file"
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open(fname)

wb.SaveAs(fname+"x", FileFormat = 51)    #FileFormat = 51 is for .xlsx extension
wb.Close()                               #FileFormat = 56 is for .xls extension
excel.Application.Quit()

Tried @Jhon's solution 1st, then I turned into pyexcel as a solution

pyexcel.save_as(file_name=oldfilename, dest_file_name=newfilename)

It works properly until I tried to package my project to a single exe file by PyInstaller, I tried all hidden imports option, following error still there:

  File "utils.py", line 27, in __enter__
    pyexcel.save_as(file_name=self.filename, dest_file_name=newfilename)
  File "site-packages\pyexcel\core.py", line 77, in save_as
  File "site-packages\pyexcel\internal\core.py", line 22, in get_sheet_stream

pyexcel_io.exceptions.SupportingPluginAvailableButNotInstalled: Please install p

[3192] Failed to execute script

Then, I jumped to pandas:

pd.read_excel(oldfilename).to_excel(newfilename, sheet_name=self.sheetname,index=False)

Update @ 21-Feb 2020

openpyxl provides the function: append

enable the ability to insert rows to a xlxs file which means user could read the data from a xls file and insert them into a xlsx file.

• append([‘This is A1’, ‘This is B1’, ‘This is C1’])
• or append({‘A’ : ‘This is A1’, ‘C’ : ‘This is C1’})
• or append({1 : ‘This is A1’, 3 : ‘This is C1’})

Appends a group of values at the bottom of the current sheet:

• If it’s a list: all values are added in order, starting from the first column
• If it’s a dict: values are assigned to the columns indicated by the keys (numbers or letters)

CONVERT XLS FILE TO XLSX

Using python3.6 I have just come accross the same issue and after hours of struggle I solved it by doing the ff, you probably wont need all of the packages: (I will be as clear as posslbe)

make sure to install the following packages before proceeding

pip install pyexcel, pip install pyexcel-xls, pip install pyexcel-xlsx,

pip install pyexcel-cli

step 1:

import pyexcel

step 2: "example.xls","example.xlsx","example.xlsm"

sheet0 = pyexcel.get_sheet(file_name="your_file_path.xls", name_columns_by_row=0)

step3: create array from contents

xlsarray = sheet.to_array() 

step4: check variable contents to verify

xlsarray

step5: pass the array held in variable called (xlsarray) to a new workbook variable called(sheet1)

sheet1 = pyexcel.Sheet(xlsarray)

step6: save the new sheet ending with .xlsx (in my case i want xlsx)

sheet1.save_as("test.xlsx")

Answer 6

Well I kept it simple and tried with Pandas:

import pandas as pd

df = pd.read_excel (r'Path_of_your_file\\name_of_your_file.xls')

df.to_excel(r'Output_path\\new_file_name.xlsx', index = False)
