Open MS Excel Spreadsheet with Python

P: n/a
Hi Folks,

I'm a brand new Python programmer, so please point me in the right
direction if this is not the best forum for this question....

I would like to open an existing MS Excel spreadsheet and extract
information from specific worksheets and cells.

I'm not really sure how to get started with this process.
I ran the COM Makepy utility from my PythonWin (IDE from ActiveSTate),
using Microsoft Excel 10.0 Object Library, then
import win32com.client
xl = win32com.client.Dispatch("Excel.Application")
wb = xl.Workbooks.Open ("c:\\data\\myspreadsheet.xls")

Then, I get errors when I try the following:
sh = wb.worksheets(1)
I think I'm missing something fairly fundamental, but I've googled all
over the place and can't seem to find anything very introductory about
opening and using data from MS Excel using Python. Any suggestions,
including places to get more information are welcome.

Also, do I need to run the makepy utility every time I run my script?
If so, how would I do it from within my Python program, rather than with
the GUI in the IDE?

Thanks for your help,

Allison

Probably are. Do you use http://groups.google.com to search the
archives of this mailing list? If you go there, and search for

excel group:*python*

you'll likely find everything you need to know.

In a nutshell, using the win32 extensions you can access excel
directly. On other platforms, you'll probably need to go with an
xl->csv converter, and then either parse the csv yourself or use the
excellent csv module (http://object-craft.com.au/projects/csv); note
that a csv module will be standard with the python library as of
python 2.3. If you decide to go this route, let me know: I do a lot
of XL->CSV work in python and have a few utility functions that may
come in handy.

Hi!

You can save the spreadsheet in XML format. This can be parsed and
modified. This has the advantage that it works on all plattforms.

I wrote a small receipe in the python cookbook some months ago.

I would like to open an existing MS Excel spreadsheet and extract
information from specific worksheets and cells.
First things first:

Python programming on Win32 : [help for Windows programmers] / Mark
Hammond and Andy Robinson. - 1. ed.
Beijing [u.a.] : O'Reilly, 2000. - XVII, 652 S. : Ill.
ISBN 1-56592-621-8

Lots of material about MS Excel <-> Python. Uses Python 1.5.2, but most
of the code works with later versions.

And of course, use your Excel VBA help to get the object and method
names right.
I'm not really sure how to get started with this process.
I ran the COM Makepy utility from my PythonWin (IDE from ActiveSTate),
using Microsoft Excel 10.0 Object Library, then
import win32com.client
xl = win32com.client.Dispatch("Excel.Application")
wb = xl.Workbooks.Open ("c:\\data\\myspreadsheet.xls")

Then, I get errors when I try the following:
sh = wb.worksheets(1)

Most probably a simple case sensitivity problem:

sh = wb.Worksheets(1)

sh = wb.ActiveSheet might be better, depending on context.

Also, do I need to run the makepy utility every time I run my script?

No, just once. I don't know anything about deploying, though.

Your code worked on my system. However, I have found this interface to be
pretty tricky. It often happens that while you are debugging the program you
generate an instance of Excel which then makes later operations bomb
mysteriously. On XP, hit Ctrl-Alt-Del tp bring up the task manager and then
look at the Processes tab. If you have an instance of Excel running you
should see it there. Use End Process to get rid of it.
Very true (but as I read the original post, the exceptions start at
first try).
You can avoid these problems by making sure that any COM references you make
get released properly if an exception occurs. Your script would look like
this:

import win32com.client
xl = win32com.client.Dispatch("Excel.Application")
try:
wb = xl.Workbooks.Open ("c:\\data\\myspreadsheet.xls")
try:
sh = wb.worksheets(1)
try:
print sh.Cells(2,3)
except:
sh = None
raise
sh = None
except:
wb.Close()
wb = None
raise
wb.Close()
wb = None
except:
xl = None
raise
xl = None

There are more elegant ways of doing this using classes. However, with this
code I think you will never see one of those mysterious Excel instances in
your task manager.

I think try / finally would be better. Explicitly deleting all three:
sh, wb and xl is the key to not having Excel zombies, if there is an
exception or not.

That's a small bug in the easyExcel class of the Hammond book: it only
deletes xl, not the variable representing the Workbook. So you still get
your zombie.

After running makepy, your methods become case sensitive. They are
case insensitive before makepy. You probably need 'wb.Worksheets(1)'

At this point, I don't believe you're doing Python any more, but
Visual Basic for Applications
Then, I get errors when I try the following:
sh = wb.worksheets(1)

Is worksheets the proper term or should it be Sheets? Probably depends
on the version of Excel/VBA

Im looking at "Python Programming on Win32", an Oreilly book. If you
really must work with Excel or Word you should get it.

Try
sh=wb.Sheets[1] OR sh=xl.Workbooks[0].Sheets[1] You need to have only 1 Workbook open or the one you
want, must be the first one
xl.Workbooks[0].Sheets[1]==wb.Sheets[1]

Hi,
I am working on Python-Excel interface based on the excellent library
win32com.
I was planning to put it up as a Python recipe in Activestate.
Anyway before that I shall personally send you the code after some
cleanup. It will be good to get an early feedback before I upload it
in Activestate.

Thanks to everyone for suggestions, hints, and code, particularly the
ideas about where to find more information. I know that MS Excel is
not every Open Source-er's idea of a good time, but my plan is to get
my data out of there as fast as I can and do the fun stuff in Python!

It turns out, as some people pointed out, that after running the
makepy utility, the methods become case-sensitive, so it should have
read:
sh = wb.Worksheets(1)
and everything would have gone smooth as silk!

And yes, I would love to preview Excel/Python code if you would like
to pass it along to me.

There's an excellent utility called xlhtml, which converts XLS
spreadsheets to HTML files, available at
http://chicago.sourceforge.net/xlhtml/

I made a simple Python wrapper, which uses xlhtml and parses the
converted spreadsheet into a Python Numeric array. As I didn't need to
do any calculations with the data, you only get cell contents as string
objects at this time.

Note that using this method you only need freely available tools, no
excel or windows. Also, it isn't necessary to open and save the
spreadsheet as a CSV or XML file, which is nice if you need to batch
process lots of spreadsheets.

Take a look at akaihola.iki.fi/comp/python and drop me a note if you
make improvements to the code.

Hello Members,
I would like to share the Python-Excel Interface code.
This is based on sample code from Mark Hammond and Andy Robinson's
"Python Programming on Win32"
I use Python 2.3 and Win32all-157 on a Win 98 machine.
I look forward to feedback on how to improve this code. If I get good
response I may think of putting up this code as a Python recipe in
Activestate.
Once again hats off to Mark Hammond for his excellent Win32all
library.

Regards,
Srijit

Hi Folks,

I'm a brand new Python programmer, so please point me in the right
direction if this is not the best forum for this question....

I would like to open an existing MS Excel spreadsheet and extract
information from specific worksheets and cells.

I'm not really sure how to get started with this process.
I ran the COM Makepy utility from my PythonWin (IDE from ActiveSTate),
using Microsoft Excel 10.0 Object Library, then
import win32com.client
xl = win32com.client.Dispatch("Excel.Application")
wb = xl.Workbooks.Open ("c:\\data\\myspreadsheet.xls")

Then, I get errors when I try the following:
sh = wb.worksheets(1)
I think I'm missing something fairly fundamental, but I've googled all
over the place and can't seem to find anything very introductory about
opening and using data from MS Excel using Python. Any suggestions,
including places to get more information are welcome.

Also, do I need to run the makepy utility every time I run my script?
If so, how would I do it from within my Python program, rather than with
the GUI in the IDE?

Thanks for your help,

Allison

P: n/a
Would it be possible to give a step-by-step guide on how to use the
script, ie, what should one do in an interactive Python session to use
one or two of the functions in the script?

Hello Members,
I would like to share the Python-Excel Interface code.
This is based on sample code from Mark Hammond and Andy Robinson's
"Python Programming on Win32"
I use Python 2.3 and Win32all-157 on a Win 98 machine.
I look forward to feedback on how to improve this code. If I get good
response I may think of putting up this code as a Python recipe in
Activestate.
Once again hats off to Mark Hammond for his excellent Win32all
library.

Regards,
Srijit

sr****@yahoo.com wrote in message news:<22*************************@posting.google.c om>... Hello Members,
I would like to share the Python-Excel Interface code.
This is based on sample code from Mark Hammond and Andy Robinson's
"Python Programming on Win32"
I use Python 2.3 and Win32all-157 on a Win 98 machine.
I look forward to feedback on how to improve this code. If I get good
response I may think of putting up this code as a Python recipe in
Activestate.
Once again hats off to Mark Hammond for his excellent Win32all
library.

Regards,

Hi,
I am working on Python-Excel interface based on the excellent library
win32com.
I was planning to put it up as a Python recipe in Activestate.
Anyway before that I shall personally send you the code after some
cleanup. It will be good to get an early feedback before I upload it
in Activestate.

Hi Folks,

I'm a brand new Python programmer, so please point me in the right
direction if this is not the best forum for this question....

I would like to open an existing MS Excel spreadsheet and extract
information from specific worksheets and cells.

I'm not really sure how to get started with this process.
I ran the COM Makepy utility from my PythonWin (IDE from ActiveSTate),
using Microsoft Excel 10.0 Object Library, then
import win32com.client
xl = win32com.client.Dispatch("Excel.Application")
wb = xl.Workbooks.Open ("c:\\data\\myspreadsheet.xls")

Then, I get errors when I try the following:
sh = wb.worksheets(1)
I think I'm missing something fairly fundamental, but I've googled all
over the place and can't seem to find anything very introductory about
opening and using data from MS Excel using Python. Any suggestions,
including places to get more information are welcome.

Also, do I need to run the makepy utility every time I run my script?
If so, how would I do it from within my Python program, rather than with
the GUI in the IDE?

Thanks for your help,

Allison
