I am using NPOI to process data in Excel 2003 (xls) file. This is my code

if (excelFormat.Equals(Constants.XLS_EXCEL_FORMAT))
{
using (FileStream file = new FileStream(filePath, FileMode.Open, FileAccess.Read))
{
wbImportXLS = new HSSFWorkbook(file); //crash here
}
sheetImport = wbImportXLS.GetSheet(CommonController.GetFirstSheetNameInFileXLS(wbImportXLS));
isXLS = true;
}

However I receive an error

"The supplied POIFSFileSystem does not contain a BIFF8 'Workbook' entry. Is it really an excel file?"

I checked my excel file. That is not contain any password. I used Apache Tika and received this information

Hi all, I need a small help with NPOI and asp.net.
I'm trying to create an excel file from a web application, written in asp.net (vb).
Everything is fine with excel 2003 xls format, while using the XSSF object model I get corrupted files.
Opening files in Excel I get the message that says file is corrupted, and can be restored (and actually Excel repairs it). The problem occurs even if I try to save stream into a file, rather than using memorystream.
Help is appreciated...
Here's the code, see attachment for error:

Dim wb As New XSSFWorkbook
Dim ws As new XSSFSheet
ws = wb.CreateSheet("Sheet1")
Dim r As XSSFRow
r = ws.CreateRow(0)
Dim c = r.CreateCell(0)
c.SetCellValue("Test")

Dim m As New IO.MemoryStream
m.Flush()
wb.Write(m)

Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
Response.AddHeader("content-disposition", "attachment;filename=test.xlsx")
Response.Clear()
Response.BinaryWrite(m.GetBuffer())

Response.End()

This may be a duplicate of [12616](https://npoi.codeplex.com/workitem/12616), but after much research, I haven't been able to track down a solution.

I compiled NPOI from source in Visual Studio 2013 with a direct pull from GitHub - the NPOI version is 2.0.8. The issue occurs with the NPOI NuGet package as well. I am opening the file with Excel 2010. Consider the following:

```
IWorkbook wb = null;
string file = "numbers.xlsx";

using (FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read)) {
if (Path.GetExtension(file).Contains("xlsx")) {
wb = new XSSFWorkbook(fs);
} else {
wb = new HSSFWorkbook(fs);
}
}

using (FileStream fs = new FileStream(file, FileMode.Open, FileAccess.ReadWrite)) {
wb.Write(fs);
}
```

This will render the output XLSX file unusable. [Case in point on Excel's reaction](http://imgur.com/AMglz1Y,bcCXi0d).

Workbooks created/written in-code with the XSSF API open correctly. XLS files opened/written with the HSSF API are fine with respect to Excel.

The FileMode/FileAccess/FileShare options for the FileStream do not seem to make a difference.

In practice I have been opening far more complex XLSX files, writing a few new cells to the rows therein, and writing back, where after the spreadsheet cannot be opened or subsequently recovered.

I've attached the aforementioned XLSX spreadsheet for testing purposes. Thanks for having a look.
Comments: ** Comment from web user: SachaK **

If the file stream is created with FileMode.Create instead of FileMode.Open it works fine. It's confusing because it works with both for xls files.

Hi.

Sheet sample:
```
|Data1|Data2|Data3|
|-----|-----|-----|
| 1| 2| 3|
| 4| 5| 6|
| 7| 8| 9|
```

Name Data1 is represented as __Table1[Data1]__. I can get actual cell range __=Sheet1!$A$2:$A$4__ if I delete and convert the table to ranges.


C# problem code:
```
XSSFWorkbook workbook = new XSSFWorkbook(fs);
var name = workbook.GetName("Data1");
var cells = new AreaReference(name.RefersToFormula);
```

AreaReference throws FormatException.

Another approach? I have tried ILSpy. Here is another one:
```
XSSFWorkbook workbook = new XSSFWorkbook(fs);
XSSFEvaluationWorkbook ev = XSSFEvaluationWorkbook.Create(workbook);
var name = workbook.GetName("Data1");
var ptgs = FormulaParser.Parse(name.RefersToFormula, ev);
```

Result:
* FormulaParseException: Specified named range 'Table1' does not exist in the current workbook.

Any good workaround?

I have a template and after filling it with values I set a background color but for a small file (about 6000 rows) it takes about 4 minutes. Whithout setting background color it takes only 8 seconds.

My code is:
var hssfworkbook = new XSSFWorkbook(file);
var sheet = hssfworkbook.GetSheetAt(0);

for (int i=0; i<sheet.LastRowNum; i++)
{
var currentCellStyle = hssfworkbook.CreateCellStyle();
currentCellStyle.FillForegroundColor = IndexedColors.Green.Index;
currentRow.Cells.ForEach(x=> x.CellStyle = currentCellStyle);
}

When setting data validation to an explicit list in excel, say 1 and 2, NPOI reads the datavalidation formula enclosed in an extra double quotes: ""1,2"" instead of "1,2", resulting in the ExplicitValues array to also contains the quotes.

Hi Team /All.

I'm new to NPOI, I had started today and I must say well done !.
I have the following issue and I hope you can help / explain it to me.

I would like to write 10 different cells to a xls file, But i must save the file after each modification.
I tried to use the ".Write(file)" method and I get a big file but with results of only the first save. (all other 9 changes are not saved).

I tried to search for this issue but I could not find an answer.

Thanks in advance,
Eyal.

Hi, I' have this round problem: the number 37803.49142 was being used in the Excel ROUND() function to 0dp. e.g. ROUND(37803.49142, 0)

When executing this using the same workbook:

Excel would evaluate to 37803
NPOI would evaluate to 37804

Any suggestion? Is it a NPOI bug?

Thanks in advance.
