I am unable to find examples where xlwt is used to write into existing files. I have a existing xls file that I need to write to. When I use xlrd to read the file, I cant seem to figure out how to transform the "Book" type returned into a xlwt.Workbook. I would appreciate if someone can point me to an example. Greg Here's some sample code I used recently to do just that. It opens a workbook, goes down the rows, if a condition is met it writes some data in the row. Finally it saves the modified file. from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils from xlrd import open

问题 I\'m looking for the best approach for inserting a row into a spreadsheet using openpyxl. Effectively, I have a spreadsheet (Excel 2007) which has a header row, followed by (at most) a few thousand rows of data. I\'m looking to insert the row as the first row of actual data, so after the header. My understanding is that the append function is suitable for adding content to the end of the file. Reading the documentation for both openpyxl and xlrd (and xlwt), I can\'t find any clear cut ways of

问题 I am trying to create an Excel workbook where I can auto-set, or auto-adjust the widths of the columns before saving the workbook. I have been reading the Python-Excel tutorial in hopes of finding some functions in xlwt that emulate xlrd ones (such as sheet_names() , cellname(row, col) , cell_type , cell_value , and so on...) For example, suppose I have the following: from xlwt import Workbook wb = Workbook() sh1 = wb.add_sheet(\'sheet1\' , cell_overwrite_ok = True) sh2 = wb.get_sheet(0) wb

问题 In the documentation for xlrd and xlwt I have learned the following: How to read from existing work-books/sheets: from xlrd import open_workbook wb = open_workbook(\"ex.xls\") s = wb.sheet_by_index(0) print s.cell(0,0).value #Prints contents of cell at location a1 in the first sheet in the document called ex.xls How to create new work-books/sheets: from xlwt import Workbook wb = Workbook() Sheet1 = wb.add_sheet(\'Sheet1\') Sheet1.write(0,0,\'Hello\') wb.save(\'ex.xls\') #Creates a document

Preserving styles using python's xlrd,xlwt, and xlutils.copy

由 此生再无相见时 提交于 2019-11-26 01:07:34
问题 I\'m using xlrd , xlutils.copy , and xlwt to open up a template file, copy it, fill it with new values, and save it. However, there doesn\'t seem to be any easy way to preserve the formatting of the cells; it always gets blown away and set to blank. Is there any simple way I can do this? Thanks! /YGA A sample script: from xlrd import open_workbook from xlutils.copy import copy rb = open_workbook(\'output_template.xls\',formatting_info=True) rs = rb.sheet_by_index(0) wb = copy(rb) ws = wb.get
