pyexcel-ods is a tiny wrapper library to read, manipulate and write data in ods fromat using python 2.6 and python 2.7. You are likely to use it with pyexcel. pyexcel-ods3 is a sister library that does the same thing but supports Python 3.3 and 3.4.

Installation

You can install it via pip:

$ pip install pyexcel-ods

or clone it and install it:

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

Usage

As a standalone library

Read from an ods file

Here’s the sample code:

from pyexcel_ods import ODSBook

book = ODSBook("your_file.ods")
# book.sheets() returns a dictionary of all sheet content
#   the keys represents sheet names
#   the values are two dimensional array
print(book.sheets())

Write to an ods file

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

from pyexcel_ods import ODSWriter

data = {
    "Sheet 1": [[1, 2, 3], [4, 5, 6]],
    "Sheet 2": [["row 1", "row 2", "row 3"]]
}
writer = ODSWriter("your_file.ods")
writer.write(data)
writer.close()

Read from an ods from memory

Here’s the sample code:

from pyexcel_ods import ODSBook

# This is just an illustration
# In reality, you might deal with ods file upload
# where you will read from requests.FILES['YOUR_ODS_FILE']
odsfile = "example.ods"
with open(odsfile, "rb") as f:
    content = f.read()
    book = ODSBook(None, content)
    print(book.sheets())

Write an ods to memory

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

from pyexcel_ods import ODSWriter
from StringIO import StringIO

data = {
    "Sheet 1": [[1, 2, 3], [4, 5, 6]],
    "Sheet 2": [["row 1", "row 2", "row 3"]]
}
io = StringIO()
writer = ODSWriter(io)
writer.write(data)
writer.close()
# do something witht the io
# In reality, you might give it to your http response
# object for downloading

As a pyexcel plugin

Import it in your file to enable this plugin:

from pyexcel.ext import ods

Please note only pyexcel version 0.0.4+ support this.

Reading from an ods file

Here is the sample code:

from pyexcel import Reader
from pyexcel.ext import ods
from pyexcel.utils import to_array
import json

# "example.ods"
reader = Reader("example.ods")
data = to_array(reader)
print json.dumps(data)

Writing to an ods file

Here is the sample code:

from pyexcel import Writer
from pyexcel.ext import ods

array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
writer = Writer("output.ods")
writer.write_array(array)
writer.close()

Reading from a StringIO instance

You got to wrap the binary content with StringIO to get odf working:

import pyexcel
from pyexcel.ext import ods
from StringIO import StringIO

# This is just an illustration
# In reality, you might deal with ods file upload
# where you will read from requests.FILES['YOUR_ODS_FILE']
odsfile = "example.ods"
with open(odsfile, "rb") as f:
    content = f.read()
    r = pyexcel.Reader(("ods", StringIO(content)))

Writing to a StringIO instance

You need to pass a StringIO instance to Writer:

import pyexcel
from pyexcel.ext import ods
from StringIO import StringIO


data = [
    [1, 2, 3],
    [4, 5, 6]
]
io = StringIO()
w = pyexcel.Writer(("ods",io))
w.write_rows(data)
w.close()
# then do something with io
# In reality, you might give it to your http response
# object for downloading

Dependencies

  1. odfpy
