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!

>>> data.xls('people.xls')

It’s that easy.

Installation

To install tablib, simply:

$ pip install tablib

Or, if you absolutely must:
