Tablib is a format-agnostic tabular dataset library, written in Python. 

Output formats supported:

- Excel
- JSON
- YAML
- CSV

At this time, Tablib supports the **export** of it's powerful Dataset object instances into any of the above formats. Import is underway.

Note that tablib *purposefully* excludes XML support. It always will.


Usage
-----

    
Populate fresh data files: ::
    
    headers = ('first_name', 'last_name')

    data = [
        ('John', 'Adams'),
        ('George', 'Washington')
    ]
    
    data = tablib.Dataset(*data, headers=headers)


Intelligently add new rows: ::

    >>> data.append(('Henry', 'Ford'))

Intelligently add new columns: ::

    >>> data.append(col=('age', 90, 67, 83))
    
Slice rows:  ::

    >>> print data[:2]
    [('John', 'Adams', 90), ('George', 'Washington', 67)]
    

Slice columns by header: ::

    >>> print data['first_name']
    ['John', 'George', 'Henry']

Easily delete rows: ::

    >>> del data[1]

Drumroll please...........

JSON! 
+++++
::

	>>> print data.json
	[
	  {
	    "last_name": "Adams",
	    "age": 90,
	    "first_name": "John"
	  },
	  {
	    "last_name": "Ford",
	    "age": 83,
	    "first_name": "Henry"
	  }
	]
	

YAML! 
+++++
::

	>>> print data.yaml
	- {age: 90, first_name: John, last_name: Adams}
	- {age: 83, first_name: Henry, last_name: Ford}
	
CSV... 
++++++
::

	>>> print data.csv
	first_name,last_name,age 
	John,Adams,90 
	Henry,Ford,83 
	
EXCEL! 
++++++
::

	>>> open('people.xls').write(data.xls)
		
It's that easy.

Roadmap
-------
- Add ability to add/remove full columns
- Import datasets from CSV, JSON, YAML
- Release CLI Interface
- Auto-detect import format
- Add possible other exports (SQL?)
- Possibly plugin-ify format architecture
- Ability to assign types to rows (set, regex=, &c.)
- Plugin support
