A wrapper library to read, manipulate and write data in xlsx and xlsm format

Project description

https://travis-ci.org/chfw/pyexcel-xlsx.svg https://coveralls.io/repos/chfw/pyexcel-xlsx/badge.png?branch=master

pyexcel-xlsx is a tiny wrapper library to read, manipulate and write data in xlsx and xlsm fromat using openpyxl. You are likely to use it with pyexcel.

Known constraints

Fonts, colors and charts are not supported.

Installation

You can install it via pip:

$ pip install pyexcel-xlsx

or clone it and install it:

$ git clone http://github.com/chfw/pyexcel-xlsx.git
$ cd pyexcel-xlsx
$ python setup.py install

Usage

As a standalone library

Write to an xlsx file

Here’s the sample code to write a dictionary to an xlsx file:

>>> from pyexcel_xlsx import save_data
>>> data = OrderedDict() # from collections import OrderedDict
>>> data.update({"Sheet 1": [[1, 2, 3], [4, 5, 6]]})
>>> data.update({"Sheet 2": [["row 1", "row 2", "row 3"]]})
>>> save_data("your_file.xlsx", data)

Read from an xlsx file

Here’s the sample code:

>>> from pyexcel_xlsx import get_data
>>> data = get_data("your_file.xlsx")
>>> import json
>>> print(json.dumps(data))
{"Sheet 1": [[1, 2, 3], [4, 5, 6]], "Sheet 2": [["row 1", "row 2", "row 3"]]}

Write an xlsx to memory

Here’s the sample code to write a dictionary to an xlsx file:

>>> from pyexcel_xlsx import save_data
>>> data = OrderedDict()
>>> data.update({"Sheet 1": [[1, 2, 3], [4, 5, 6]]})
>>> data.update({"Sheet 2": [[7, 8, 9], [10, 11, 12]]})
>>> io = StringIO()
>>> save_data(io, data)
>>> # do something with the io
>>> # In reality, you might give it to your http response
>>> # object for downloading

Read from an xlsx from memory

Continue from previous example:

>>> # This is just an illustration
>>> # In reality, you might deal with xlsx file upload
>>> # where you will read from requests.FILES['YOUR_XLSX_FILE']
>>> data = get_data(io)
>>> print(json.dumps(data))
{"Sheet 1": [[1, 2, 3], [4, 5, 6]], "Sheet 2": [[7, 8, 9], [10, 11, 12]]}

As a pyexcel plugin

Import it in your file to enable this plugin:

from pyexcel.ext import xlsx

Please note only pyexcel version 0.0.4+ support this.

Reading from an xlsx file

Here is the sample code:

>>> import pyexcel as pe
>>> from pyexcel.ext import xlsx
>>> sheet = pe.get_book(file_name="your_file.xlsx")
>>> sheet
Sheet Name: Sheet 1
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet Name: Sheet 2
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+

Writing to an xlsx file

Here is the sample code:

>>> sheet.save_as("another_file.xlsx")

Reading from a IO instance

You got to wrap the binary content with stream to get xlsx working:

>>> # This is just an illustration
>>> # In reality, you might deal with xlsx file upload
>>> # where you will read from requests.FILES['YOUR_XLSX_FILE']
>>> xlsxfile = "another_file.xlsx"
>>> with open(xlsxfile, "rb") as f:
...     content = f.read()
...     r = pe.get_book(file_type="xlsx", file_content=content)
...     print(r)
...
Sheet Name: Sheet 1
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet Name: Sheet 2
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+

Writing to a StringIO instance

You need to pass a StringIO instance to Writer:

>>> data = [
...     [1, 2, 3],
...     [4, 5, 6]
... ]
>>> io = StringIO()
>>> sheet = pe.Sheet(data)
>>> sheet.save_to_memory("xlsx", io)
>>> # then do something with io
>>> # In reality, you might give it to your http response
>>> # object for downloading
