xlrd

问题 How can I go about creating a worksheet (within an excel workbook) with a pivot table using python libs like pyExcelerator / xlrd? I need to generate a daily report that has a pivot table to summarize data on other sheets. One option would be to have a blank template that I copy and populate with the data. In this case, is there a way to refresh the pivot from code? Any other suggestions? 回答1: Please clarify (by editing your question) whether "sheet" is an abbreviation of "spreadsheet" and

I am posting my code, as well as the text that is returned when I choose to print a certain column. import xlrd data = xlrd.open_workbook('data.xls') sheetname = data.sheet_names() employees = data.sheet_by_index(0) print employees.col(2) >>>[text:u'employee_first', text:u'\u201cRichard\u201d', text:u'\u201cCatesby\u201d', text:u'\u201cBrian\u201d'] My intention is to create

问题 I am trying to read dates/time off an excel sheet using Python, but I only want to read in the time so I can perform computations on it. For example if I have a date in the format: 3/11/2003 4:03:00 AM on my excel sheet how can I read in just the 4:03:00 in Python? I ultimately want to be able to subtract hours, mins, or seconds from the read in time. 回答1: The best option would be to convert the date to datetime using xldate_as_tuple.

I am abe to fetch most of the excel files but for some excel files it gives me error as : XLRDError: Expected BOF record; found 0x213c Can anyone let me know about how to solve this issue? thanks in advance. 回答1: What you have is most probably an "XML Spreadsheet 2003 (*.xml)" file ...

问题 I'm uploading some data from an excel file using xlrd and turning that data into models (with mainly IntegerField values) in Django. My excel file has a bunch of missing data. Unfortunately, these missing data are converted to the value of 0 in my models, instead of NULL. This means that when my Person model doesn't have an age, that age gets recorded as 0, instead of as NULL. What's the best way to change this? I've tried doing this: age = models.IntegerField(blank=True, null=True) But the
