Python powered spreadsheets

Marmir is powerful and fun

Marmir takes Python data structures and turns them into spreadsheets.

It is xlwt and google spreadsheets on steroids.

It also supports: input from Django models; taking Psycopg cursors; writing out ascii tables (like psql does); and will soon support HTML tables as output. The goal is to make it easy to generate many types of useful table files with the least amount of configuration.

Marmir melts in your mouth

Installing:

$ pip install Marmir

Talk about simple to use, wow. Marmir is just this:

import datetime
import mm

now = datetime.datetime.now().replace(microsecond=0)

my_data = [ 
    {
        'msg': "My first Row",
        'id': 1,
        'when': now,
    },
    {
        'msg': "My second Row",
        'id': 2,
        'when': now,
    },

]

mm_doc = mm.Document(my_data)
mm_doc.write("example.xls")

Same example above as lists (also node the 'order' argument works in the above as well:

my_headers = ('id', 'msg', 'when')
my_data = (
    (1, "My First Row", now),
    (2, "My Second Row", now)   
)

mm_doc = mm.Document(my_data, order=my_headers)
mm_doc.write("example.xls")

Or you can get fancier:

import datetime
import mm

my_data = [ 
    {
        'msg': "My first Row",
        'id': 1,
        'when': mm.Date(datetime.datetime.now(), "%Y-%m-%dT%H:%M:%S"),
        'homepage': mm.URL("https://github.com/brianray")
    },
    {
        'msg': "My second Row",
        'id': 2,
        'when': datetime.datetime.now(),
        'homepage': mm.URL("http://twitter.com/brianray", "Tweet Me")
    },

]

mm_doc = mm.Document(my_data)
mm_doc.write("example.xls")

# also you can publish to google spreadsheats
mm_doc.write_gdata("Example Spreadsheet", "Username", "Pass")

Now for a little Django (https://www.djangoproject.com/) example:

from yourproject.models import TestModel
from mm.contrib.django.data_model import DjangoDataModel
from mm.contrib.django.grid import DjangoGrid

django_query_set = TestModel.objects.all()
mm_doc = mm.Document(django_query_set, 
              data_model_class=DjangoDataModel, 
              grid_class=DjangoGrid)
mm_doc.write("django_example.xls")

There is a lot more. Check out the Examples.

... Not in your hand

So the primary goals are:

• make XLS spreadsheets better than xlwt
• Create Spreadsheets in Google Docs
• convert python types automagically, date is a date, int is a int, string is a string, ...
• do stuff you expect like make columns wider to fit, wrap in some cases
• make stuff pretty colors and easier to read
• generate directly from Django queries

Some other stuff:

• do summaries and break out tables
• add logic and math functions
