Commented Issue: NPOI doesn't work with a Excel template with macro [3804]

Since there is no documentation one can refer to, let me ask the author whether NPOI supports Excel files with macros?
 
Probably I did something wrong, but each time I try to open such a file, fill it with data and save it via NPOI, the resulting file gets corrupted. Excel opens it but is unable to save. Once macros are eliminated, everything goes smooth. Could you please tell me where the problem is?
 
Thank you.

can the current version of NPOI now support VBA programming ?

Hi, i´m sorry but i downloaded the laste beta version 2.0 beta 1 released on march 6, and i´m still having the same problem, cell with a value like 155,000 where the "," char is the miles separator, are readed like only 155 instead of 155000.

In fact, the real cell value is "155,000 L" wich i expected to be a string value (so i can parse the base unit liters and the actual number 155000), but instead it´s readed like a number.

Maybe i´m doing something wrong, can u help me?

Is there a way to add a picture line border to a picture that has been inserted into an anchor tag on a given worksheet? If so, how would this be done?

At the moment I need 3 specific columns from an xls file and have been loading the whole sheet into a datatable. From there I am deleting rows and columns I do not need. It is sort of working but also beginning to get sloppy I feel.

Does anyone have an idea for me to pull those columns directly or possibly another way to approach this? Thanks!

Guys, can I populate an excel file (xlsx) with that 'Format as Table' feature? I haven't found a way to create it through code, neither putting it on my template.
Is there some class that helps me with it?.

Thanks anyway!

Hi all,

I wanna use npoi to manipulate .xlsx files in VS2012/2010. To do so I should import NPOI.XSSF.UserModel, but when I add the npoi.dll and try to import that, there is no XSSF type of NPOI at Using part. I mean that there is no "Using NPOI.XSSF"
Any help?

If you read an existing xls template with comment in it and then save it as a new xls, the comment will be lost and Excel will say 'file data lost' in some cases. This is confirmed as a bug in all previous version of NPOI. It's plan to be fixed in NPOI 2.0.

I have a situation where I have to open several XLSM files. Only about 50% of them work with the NPOI 2.0.
 
I get a failure similar to the following: The 'br' start tag on line 19 position 12 does not match the end tag of 'font'. Line 20, position 9.
 
The relevent stack trace is as follows:

I found that the EPPlus Excel library is able to read all the files without issue. I prefer NPOI but have to have a working solution by the next 2 weeks. Hope there is an easy fix for the Alpha release.
 
For proprietary reasons I cannot attach the XLSM file. Thanks!

This looks to be a new feature in Office 2007 or above because the file format is xlsx. I'm afraid it's not supported so far.

I want to fetch the data from the excel Sheet provided to the user and i am using NPOI from nuGate Package.

If my excel sheet made in the MSOffice2007 then it is working fine. but if file made in 2010 then it it throwing an error related to hssf

Help me in that
Comments: ** Comment from web user: tonyqus **

HSSF is not the correct class for xlsx files. Instead, you have to use XSSF. But XSSF is only available in NPOI 2.0.

That's what I thought. I spent some time researching on poi too, but nothing came out of it.
If anybody is going through that pass, I suggest the same approach I worked on, using an Excel Macro. Any help needed with that, mail me.

Aside from that issue, NPOI has been a great tool to use when dealing with Excel. Thanks tony!

Hi all,
When I insert secord picture in Xlsx file, it always replace first one.
Any help?

IWorkbook workbook = new XSSFWorkbook();
ISheet sheet1 = workbook.CreateSheet("PictureSheet");

IDrawing patriarch = sheet1.CreateDrawingPatriarch();
//create the anchor
XSSFClientAnchor anchor = new XSSFClientAnchor(500, 200, 0, 0, 2, 2, 4, 7);
anchor.AnchorType = 2;
//load the picture and get the picture index in the workbook
XSSFPicture picture = (XSSFPicture)patriarch.CreatePicture(anchor, LoadImage("../../image/HumpbackWhale.jpg", workbook));
picture.Resize(); //Note: Resize will reset client anchor you set.


XSSFClientAnchor anchor2 = new XSSFClientAnchor(500, 200, 0, 0, 12, 2, 14, 7);
anchor2.AnchorType = 2;
XSSFPicture picture2 = (XSSFPicture)patriarch.CreatePicture(anchor2, LoadImage("../../image/pic2.jpg", workbook));
picture2.Resize();

FileStream sw = File.Create("test.xlsx");
workbook.Write(sw);
sw.Close();

Hi folks,

When I wrtie to an .XLS file there is no problem, it works correct. But when I write to a .XLSX file the file is messed up. Mu code is ±

private IWorkbook wb;

// Class and code

                FileStream file = new FileStream(bestand, FileMode.Open, FileAccess.Read);

                string ext = Path.GetExtension(bestand).ToLower();

                if (ext == ".xls")
                {
                    wb = new HSSFWorkbook(file);
                }
                else if (ext == ".xlsx")
                    wb = new XSSFWorkbook(file);

                ISheet ws = wb.GetSheet(Maanden[maand-1]); // The month sheet

                ws.GetRow(colum).GetCell(rij++).SetCellValue(huidigedatum);
                                ws.GetRow(colum).GetCell(rij++).SetCellValue(Datarow["Factuurnummer"].ToString());
                                ws.GetRow(colum).GetCell(rij++).SetCellValue(Datarow["Omschrijving"].ToString());

                                ws.GetRow(colum++).GetCell(tbBank-1).SetCellValue((double)totaal);

It this the way to write? to an .XLSX file.

Regards rinaldo
