I'm experimenting with pyExcelerator and am reading an XLS file which
contains dates. In Excel on my Mac they look like "09/13/06". After
parsing them out of the .XLS file they are floats, e.g. 38973.0. I assume
that's an offset in days. Doing a little date math I come up with a base
date of approximately (though not quite) 1900-01-01:
>>import datetime
dt = datetime.timede lta(days=-38973)
datetime.date (2006, 9, 13) + dt
datetime.date(1 899, 12, 30)
>>datetime.date (1900, 1, 1) - dt
datetime.date(2 006, 9, 15)
Is there some way to get pyExcelerator from doing this conversion and
instead return dates as strings? If I'm reading an arbitrary worksheet and
don't know which columnn might be a date, it's kind of hard to guess.

Hi,
Yesterday I placed a bug report on PyExcelerators-Sourceforge-page... but
I am not so sure anymore, whether this is really a bug - I could imagine
that I missed something, but I don't see what. Please confirm that my bug
is due to mishandling and I will gladly retreat my bug report.
In a formula, I would like to point to a field on another worksheet.
pyExcelerator chokes on these references!

I downloaded PyExcelerator.zip as I need to write some data into Excel
files, and tried unsuccessfully to install it. I unzipped the files
into C:/Python24/Lib/site-packages/PyExcelerator, and in a python
command line window typed
>>>os.chdir("C:/Python24/Lib/site-packages/PyExcelerator")
followed by
>>>python ./setup.py install

I have just installed PyExcelerator, and now want to use it to read
Excel spreadsheets with a variable number of rows and columns and with
multiple sheets. Unfortunately, no documentation seems to accompany
PyExcelerator. Does anyone know of a good source of documentations
and/or examples? The author provides some examples, but these tend to
involve writing data into spreadsheets one cell at a time.
Thanks in advance

Hi
I would like to
1. import an existing Excel-sheet (a template)
2. and add some data to it
3. and save it under a different name afterwards.
To me it seems, that pyExcelerator does not support the reading for
modification of an Excel-sheet. It allows only the "parse_xls" but I would
like to keep the "formatting" in the template.

My program creates three lists: the first has dates expressed as
strings, the second has floats that are strictly positive, and the
third has floats that are strictly negative. I have no trouble writing
the data in these lists to a .csv file using the csv module using the
following code.
outfile = file(fn + '.csv','wb')
writer = csv.writer(outfile)
for i in range(len(dateList)):
writer.writerow(, posVals, negVals])

I'm using pyExcelerator to take a folder of CSV files and create Excel
workbooks for all of them, then generate an Excel workbook with the
data from all of them.
Everything up until here works great; next, I make a second worksheet
on the last workbook which has summary details regarding the previous
worksheet. Here I run into a problem. The Excel form

Hi all,
I was just curious if there was a built-in or a more efficient way to
do take multiple rows of information and write them into excel using
pyExcelerator. This is how I resolved the problem:
from pyExcelerator import *
data = ,,,]

Hi, I'm using PyExcelerator, and it's great, but I can't figure out a
few things:
(1) I set the cell style to '0.00%' but the style does not work.
(2) I want to place a border around the cells( x1, y1, x2, y2 ) but I
can't find any example of doing that.
Well I do see ONE example, but it erases the cells if I do it after,
or when I write to the cells that erases the outline.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
