Is it possible to insert a worksheet into an existing workbook using Python?

问题 The Problem Creation of fancy reports using Pandas and Python. Proposed Solution Using a template xlsx file containing a template sheet nicely formatted with references to another pre-populated worksheet, delete the pre-populated sheet and insert the new worksheet from pandas. The template sheet will lose the links reverting to #REF so these will need to be renamed. I tried: import os import xlrd, xlwt import envconfig swb1 = xlrd.open_workbook(os.path.join(envconfig.REPORT_WRITER_PATH,

问题 I'm trying to use pandas.read_excel to read in .xls files. It succeeds on most of my .xls files, but then for some it errors out with the following error message: Unsupported format, or corrupt file: Expected BOF record; found '\x00\x05\x16\x07\x00\x02\x00\x00' I've been trying to research why this is happening to some, but not all files. The xlrd version is 1.0.0. I tried to manually read in with xlrd.open_workbook and I get the same result. Does anyone know what file type, this BOF record

问题 I am trying to read a list of values in a column in an excel sheet. However, the length of the column varies every time, so I don't know the length of the list. How do I get python to read all the values in a column and stop when the cells are empty using xlrd? 回答1: for i in range(worksheet.nrows): will iterate through all the rows in the worksheet if you were interested in column 0 for example c0 = [worksheet.row_values(i)[0] for i in range(worksheet.nrows) if worksheet.row_values(i)[0]] or

Python Excel template read and re-write, maintaining formulae and formatting

问题 I've run the gamut and can't seem to find what I'm looking for. All threads I found here end up in dead ends for me. xlrd, xlwt, and xlutils almost do what I need, but… The basic idea is that I need to use Python to write simple data (strings) to a particular sheet of an Excel template and write out that template to a new .xls file. Reading in the template, copying it to a new workbook object, writing in the new values, and writing out the new .xls file is no problem. However, I cannot find a

Get column data by Column name and sheet name

问题 Is there a way to access all rows in a column in a specific sheet by using python xlrd. e.g: workbook = xlrd.open_workbook('ESC data.xlsx', on_demand=True) sheet = workbook.sheet['sheetname'] arrayofvalues = sheet['columnname'] Or do i have to create a dictionary by myself? The excel is pretty big so i would love to avoid iterating over all the colnames/sheets 回答1: Yes, you are looking for the col_values() worksheet method. Instead of arrayofvalues = sheet['columnname'] you need to do

Can't get Excel drop-down list (combobox) value with python

问题 I have an excel file with a drop-down list and I would like to access its current value from python. In vba the code is really simple : Sheets("name_of_my_sheet").name_of_my_list.value I looked for an equivalent in xlrd but couldn't find one. 回答1: I got my answer. The list the drop-down box is created at run time in vba so you can't "read" its value from the xls. The solution is to write in VBA an on change method that will actually write the value to the cell under the box. Sub My_List
