Hi,

I'm making first attempts to modify a few cells of an openoffice
spreadsheet.

I thought I'll start with ooolib as it seems rather simple.

( linux / open office 3.1 / ooolib-python-0.0.16 )

My first test was just to open a spread sheet


import ooolib
doc = ooolib.Calc()
doc.load("doc1.ods") # load calc file
doc.set_sheet_index(0) # select first sheet
doc_dims = doc.get_sheet_dimensions() # get sheet dimensions
print "dims",doc_dims # and print them out
doc.save("doc2.ods") # save 'unmodfified' file


Extracting data works perfectly.

However the saved file lost all its formating and keeps only the data.

What am I doing wrong?

My goal is to just change one cell value, but to keep all the formatting
(at least of the other cells)


thanks for any hints

Try the xlrd and xlwt modules, and the documentation at

Thanks Kumar,

I installed xlrd, xlwt and xlsutils

Now I'm stuck with exactly the same probem, that I had with ooolib.
The newly written file lost all formating and replaced formulas with the
calculated values.


Does anyone have a simple example, which reads a file, modifies one cell
and writes out WITHOUT oss of formatting / formulas?


from xlrd import open_workbook
from xlutils.copy import copy

rb = open_workbook('doc1.xls')
print "WB with %d sheets" % rb.nsheets
wb = copy(rb)
wb.save("doc2.xls") # file is created, but ALL formattng is lost and
formulas are now diplayed as text

Well the xlsutils documentation states clearly:

So probably I can't use xlrd / xlwt to perform my desired task. :-(
(Or it least I don't know how)

For extracting data or creating xls from scratch t seems rather nice though


bye

The tutorial here is beautifully done:

http://python-excel.googlegroups.com/web/python-excel.pdf?gda=68Un3kIAAABrjVmXvI2FnKbK79o6Y1oCuHLcf1VKsaM-EVGjvOiGtNXEtWX7y7b6ByPnawQ3OxpV4u3aa4iAIyYQIqbG9naPgh6o8ccLBvP6Chud5KMzIQ

Does it fly with .ods files?
