**pyexcel-ods** is a tiny wrapper library to read, manipulate and write data in
ods format using python 2.6 and python 2.7. You are likely to use it with
`pyexcel <https://github.com/pyexcel/pyexcel>`_.
`pyexcel-ods3 <https://github.com/pyexcel/pyexcel-ods3>`_ is a sister library that
depends on ezodf and lxml. `pyexcel-odsr <https://github.com/pyexcel/pyexcel-odsr>`_
is the other sister library that has no external dependency but do ods reading only
Support the project

Known constraints
==================
Fonts, colors and charts are not supported.
Installation
================================================================================
You can install pyexcel-ods via pip:
.. code-block:: bash
$ pip install pyexcel-ods
or clone it and install it:
.. code-block:: bash
$ git clone https://github.com/pyexcel/pyexcel-ods.git
$ cd pyexcel-ods
$ python setup.py install
Usage
================================================================================
As a standalone library
--------------------------------------------------------------------------------
Write to an ods file
********************************************************************************
Here's the sample code to write a dictionary to an ods file:
.. code-block:: python
>>> from pyexcel_ods 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.ods", data)
Read from an ods file
********************************************************************************
Here's the sample code:
.. code-block:: python
>>> from pyexcel_ods import get_data
>>> data = get_data("your_file.ods")
>>> import json
>>> print(json.dumps(data))
{"Sheet 1": [[1, 2, 3], [4, 5, 6]], "Sheet 2": [["row 1", "row 2", "row 3"]]}
Write an ods to memory
********************************************************************************
Here's the sample code to write a dictionary to an ods file:
.. code-block:: python
>>> from pyexcel_ods 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 ods from memory
********************************************************************************
Continue from previous example:
.. code-block:: python
>>> # This is just an illustration
>>> # In reality, you might deal with ods file upload
>>> # where you will read from requests.FILES['YOUR_ODS_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]]}
Pagination feature
********************************************************************************
Special notice 30/01/2017: due to the constraints of the underlying 3rd party
library, it will read the whole file before returning the paginated data. So
at the end of day, the only benefit is less data returned from the reading
function. No major performance improvement will be seen.
With that said, please install `pyexcel-odsr <https://github.com/pyexcel/pyexcel-odsr>`_
and it gives better performance in pagination.
Let's assume the following file is a huge ods file:
.. code-block:: python
>>> huge_data = [
... [1, 21, 31],
... [2, 22, 32],
... [3, 23, 33],
... [4, 24, 34],
... [5, 25, 35],
... [6, 26, 36]
... ]
>>> sheetx = {
... "huge": huge_data
... }
>>> save_data("huge_file.ods", sheetx)
And let's pretend to read partial data:
.. code-block:: python
>>> partial_data = get_data("huge_file.ods", start_row=2, row_limit=3)
>>> print(json.dumps(partial_data))
{"huge": [[3, 23, 33], [4, 24, 34], [5, 25, 35]]}
And you could as well do the same for columns:
.. code-block:: python
>>> partial_data = get_data("huge_file.ods", start_column=1, column_limit=2)
>>> print(json.dumps(partial_data))
{"huge": [[21, 31], [22, 32], [23, 33], [24, 34], [25, 35], [26, 36]]}
Obvious, you could do both at the same time:
.. code-block:: python
>>> partial_data = get_data("huge_file.ods",
... start_row=2, row_limit=3,
... start_column=1, column_limit=2)
>>> print(json.dumps(partial_data))
{"huge": [[23, 33], [24, 34], [25, 35]]}
As a pyexcel plugin
--------------------------------------------------------------------------------
No longer, explicit import is needed since pyexcel version 0.2.2. Instead,
this library is auto-loaded. So if you want to read data in ods format,
installing it is enough.
Reading from an ods file
********************************************************************************
Here is the sample code:
.. code-block:: python
>>> import pyexcel as pe
>>> sheet = pe.get_book(file_name="your_file.ods")
>>> sheet
Sheet 1:
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet 2:
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+
Writing to an ods file
********************************************************************************
Here is the sample code:
.. code-block:: python
>>> sheet.save_as("another_file.ods")
Reading from a IO instance
********************************************************************************
You got to wrap the binary content with stream to get ods working:
.. code-block:: python
>>> # 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 = "another_file.ods"
>>> with open(odsfile, "rb") as f:
... content = f.read()
... r = pe.get_book(file_type="ods", file_content=content)
... print(r)
...
Sheet 1:
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| 4 | 5 | 6 |
+---+---+---+
Sheet 2:
+-------+-------+-------+
| row 1 | row 2 | row 3 |
+-------+-------+-------+
Writing to a StringIO instance
********************************************************************************
You need to pass a StringIO instance to Writer:
.. code-block:: python
>>> data = [
... [1, 2, 3],
... [4, 5, 6]
... ]
>>> io = StringIO()
>>> sheet = pe.Sheet(data)
>>> io = sheet.save_to_memory("ods", io)
>>> # then do something with io
>>> # In reality, you might give it to your http response
>>> # object for downloading

Developer guide
==================
Development steps for code changes
#. git clone https://github.com/pyexcel/pyexcel-ods.git
#. cd pyexcel-ods
Upgrade your setup tools and pip. They are needed for development and testing only:
#. pip install --upgrade setuptools pip
Then install relevant development requirements:
#. pip install -r rnd_requirements.txt # if such a file exists
#. pip install -r requirements.txt
#. pip install -r tests/requirements.txt
Once you have finished your changes, please provide test case(s), relevant documentation
and update CHANGELOG.rst.
.. note::
As to rnd_requirements.txt, usually, it is created when a dependent
library is not released. Once the dependecy is installed
(will be released), the future
version of the dependency in the requirements.txt will be valid.
How to test your contribution
------------------------------
Although `nose` and `doctest` are both used in code testing, it is adviable that unit tests are put in tests. `doctest` is incorporated only to make sure the code examples in documentation remain valid across different development releases.
On Linux/Unix systems, please launch your tests like this::
$ make
On Windows systems, please issue this command::
> test.bat
Before you commit
------------------------------
Please run::
$ make format
so as to beautify your code otherwise travis-ci may fail your unit test.

So if you want to read data in ods format,\ninstalling it is enough.\n\n\nReading from an ods file\n********************************************************************************\n\nHere is the sample code:\n\n.. code-block:: python\n\n >>> import pyexcel as pe\n >>> sheet = pe.get_book(file_name=\"your_file.ods\")\n >>> sheet\n Sheet 1:\n +---+---+---+\n | 1 | 2 | 3 |\n +---+---+---+\n | 4 | 5 | 6 |\n +---+---+---+\n Sheet 2:\n +-------+-------+-------+\n | row 1 | row 2 | row 3 |\n +-------+-------+-------+\n\n\nWriting to an ods file\n********************************************************************************\n\nHere is the sample code:\n\n.. code-block:: python\n\n >>> sheet.save_as(\"another_file.ods\")\n\n\nReading from a IO instance\n********************************************************************************\n\nYou got to wrap the binary content with stream to get ods working:\n\n.. code-block:: python\n\n >>> # This is just an illustration\n >>> # In reality, you might deal with ods file upload\n >>> # where you will read from requests.FILES['YOUR_ODS_FILE']\n >>> odsfile = \"another_file.ods\"\n >>> with open(odsfile, \"rb\") as f:\n ... content = f.read()\n ... r = pe.get_book(file_type=\"ods\", file_content=content)\n ... print(r)\n ...\n Sheet 1:\n +---+---+---+\n | 1 | 2 | 3 |\n +---+---+---+\n | 4 | 5 | 6 |\n +---+---+---+\n Sheet 2:\n +-------+-------+-------+\n | row 1 | row 2 | row 3 |\n +-------+-------+-------+\n\n\nWriting to a StringIO instance\n********************************************************************************\n\nYou need to pass a StringIO instance to Writer:\n\n.. code-block:: python\n\n >>> data = [\n ... [1, 2, 3],\n ... [4, 5, 6]\n ... ]\n >>> io = StringIO()\n >>> sheet = pe.Sheet(data)\n >>> io = sheet.save_to_memory(\"ods\", io)\n >>> # then do something with io\n >>> # In reality, you might give it to your http response\n >>> # object for downloading\n\n\nLicense\n================================================================================\n\nNew BSD License\n\nDeveloper guide\n==================\n\nDevelopment steps for code changes\n\n#. git clone https://github.com/pyexcel/pyexcel-ods.git\n#. cd pyexcel-ods\n\nUpgrade your setup tools and pip. They are needed for development and testing only:\n\n#. pip install --upgrade setuptools pip\n\nThen install relevant development requirements:\n\n#. pip install -r rnd_requirements.txt # if such a file exists\n#. pip install -r requirements.txt\n#. pip install -r tests/requirements.txt\n\nOnce you have finished your changes, please provide test case(s), relevant documentation\nand update CHANGELOG.rst.\n\n.. note::\n\n As to rnd_requirements.txt, usually, it is created when a dependent\n library is not released. Once the dependecy is installed\n (will be released), the future\n version of the dependency in the requirements.txt will be valid.\n\n\nHow to test your contribution\n------------------------------\n\nAlthough `nose` and `doctest` are both used in code testing, it is adviable that unit tests are put in tests. `doctest` is incorporated only to make sure the code examples in documentation remain valid across different development releases.\n\nOn Linux/Unix systems, please launch your tests like this::\n\n $ make\n\nOn Windows systems, please issue this command::\n\n > test.bat\n\n\nBefore you commit\n------------------------------\n\nPlease run::\n\n $ make format\n\nso as to beautify your code otherwise travis-ci may fail your unit test.\n\n\nCredits\n================================================================================\n\nODSReader is originally written by `Marco Conti <https://github.com/marcoconti83/read-ods-with-odfpy>`_\n\n\nChange log\n================================================================================\n\n0.6.0 - 9.10.2020\n--------------------------------------------------------------------------------\n\n**added**\n\n#. new style reader and writer plugins. works with pyexcel-io v0.6.2\n\n0.5.6 - 19.03.2019\n--------------------------------------------------------------------------------\n\n**added**\n\n#. `#32 <https://github.com/pyexcel/pyexcel-ods/issues/32>`_, fix odfpy pinning\n#. `#33 <https://github.com/pyexcel/pyexcel-ods/issues/33>`_, fix\n IntegerAccuracyLossError on i586\n\n0.5.5 - 16.03.2019\n--------------------------------------------------------------------------------\n\n**added**\n\n#. `#32 <https://github.com/pyexcel/pyexcel-ods/issues/32>`_, fix odfpy pinning\n\n0.5.4 - 27.11.2018\n--------------------------------------------------------------------------------\n\n**added**\n\n#. `#30 <https://github.com/pyexcel/pyexcel-ods/issues/30>`_, long type will not\n be written in ods. please use string type.
