xls

I'm exporting a grid with NPOI v1.2.3, and am having trouble getting cell formatting to work. I have a class that exports a list of objects to an XLS file. A row is created for each object, and a cell is added for each configured property. The cell data format can be set on a per-property level. I've read that you shouldn't create a new style for each cell . I can't hard-code my styles, since my exporter needs to support any class. Instead, I wrote a little cache system that only creates a new CellStyle if one hasn't already been created for the current cell's format. Unfortunately, this still

I need to create a very big Excel file, but excel file in one worksheet can contain up to 65k rows. So, i want to divide all my info into several worksheets dynamical. This is my approximate code //------------------Create Excel App-------------------- Excel.Application xlApp; Excel.Workbook xlWorkBook; Excel.Worksheet xlWorkSheet; object misValue = System.Reflection.Missing.Value; xlApp = new Excel.Application(); xlWorkBook = xlApp.Workbooks.Add(misValue); xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(numberOfLetters); foreach (string letter in letters) { xlWorkSheet.Cells

I'd love a good native Python library to write XLS, but it doesn't seem to exist. Happily, Jython does. So I'm trying to decide between jexcelapi and Apache HSSF: http://www.andykhan.com/jexcelapi/tutorial.html#writing http://poi.apache.org/hssf/quick-guide.html (I can't use COM automation because I'm not on Windows, and even if I was, I couldn't afford Office licenses.) My initial thoughts are that POI/HSSF is very thorough, but also very Java-- everything seems a bit harder than it needs to be. Good documentation, but my head hurts trying to bridge the gap between what it describes and what

I need the Django Admin interface to accept administrator uploads of Excel files where the data in each Excel file is inserted into my database models. How can I make such an “Upload” button appear on a Django model admin page, where clicking the button asks the administrator to choose an .xls file, whose data then gets added to database once its upload is complete? I'm not sure about the Django side of things, but you can use xlrd to read and manipulate Excel files. There is a free PDF which explains this called Working with Excel files in Python I have done this, but I just set up a simple

导入后缀为xls或xlsx与后缀为csv文件的区别（仿sql） 一、xls xlsx文件导入 string filePath="文件路径（具体到文件名）"; string connStr="Provider=Microsoft.Jet.OleDb.4.0;" + "data source=" + filePath+ ";Extended Properties='Excel 8.0; HDR=YES; IMEX=1'""; if(文件后缀名为xlsx) { string connStr="Provider=Microsoft.Jet.OleDb.12.0;" + "data source=" + filePath+ ";Extended Properties='Excel 12.0; HDR=YES; IMEX=1'""; } OleDbDataAdapter myCommand = new OleDbDataAdapter("SELECT * FROM [工作簿名称]",connStr); DataSet myDataSet = new DataSet(); myCommand.Fill(myDataSet, "表名自定义"); 二、csv后缀的文件 string path="文件的目录名即可"; string fileName="文件名"; string connStr = @
