由于excel版本不同，python处理的时候选择的库页不同。 一、操作对应版本表格需要用到的库 1、操作xls格式的表格文件，需要用到的库如下： 读取：xlrd 写入：xlwt 修改（追加写入）：xlutils 2、操作xlsx格式的表格文件，需要用到的库如下： 读取/写入：openpyxl （好像对于xlsx格式的表格，使用xlrd也是可以读取的，只是写入会有问题，不过避免问题还是根据不同格式的表格选择对应的库吧~） 二、实现代码 1、xlwt写入xls文件内容 import xlwt def write_excel_xls(path, sheet_name, value): index = len(value) # 获取需要写入数据的行数(value是个二维数组) workbook = xlwt.Workbook() # 新建一个工作簿 sheet = workbook.add_sheet(sheet_name) # 在工作簿中新建一个表格 for i in range(0, index): for j in range(0, len(value[i])): sheet.write(i, j, value[i][j]) # 像表格中写入数据（对应的行和列） workbook.save(path) # 保存工作簿 print("xls格式表格写入数据成功！") #

The spreadsheet still displays, but with the warning message. The problem seems to occur because Excel 2007 is more picky about formats matching their extensions than earlier versions of Excel. The problem was initially discovered by an ASP.Net program and produces in the Excel error "The file you are trying to open, "Spreadsheet.aspx-18.xls', is in a different format than specified by the file extension. Verify ...". However, when I open the file it displays just fine. I am using Excel 2007. Firefox identifies the file as an Excel 97-2003 worksheet. Here is an ASP.NET page which generates the

We have a lot of spreadsheets (xls) in our source code repository. These are usually edited with gnumeric or openoffice.org, and are mostly used to populate databases for unit testing with dbUnit . There are no easy ways of doing diffs on xls files that I know of, and this makes merging extremely tedious and error prone. I've tried to converting the spreadsheets to xml and doing a regular diff, but it really feels like it should be a last resort. I'd like to perform the diffing (and merging) with git as I do with text files. How would I do this, e.g. when issuing git diff ? na_ka_na We faced

I am trying to know how many files there are in 1 specific folder with .xls extension. I read hundreds of examples with message boxes, but that is not what I'm looking for. I just want to have the number displayed into 1 cel. Is there someone who likes to help me with that please? I can not post any attempts because I can not get started :-( best regards, E. Try below code : Assign the path of the folder to variable FolderPath before running the below code. Sub sample() Dim FolderPath As String, path As String, count As Integer FolderPath = "C:\Documents and Settings\Santosh\Desktop" path =

I am developing a simple Java program to create an Excel file using (Apache POI) API. I am using Oracle 10g as a database and using the ojdbc14 JAR file. I have a table called USERINFO, having three columns, namely USERNAME , PASSWORD , and NAME. Now using Apache POI, I have been able to put all the rows in an Excel file. Since the file contains sensitive data such as username and password, I want to make it password protected. On forums, I have found how to read password protected files, but not how to create them. So how I can achieve this? Updated: As of version 3.10 POI supports encryption
