Commented Issue: XSSFWorkbook Write corrupts XLSX File [12847]
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.

Thanks for the comment nvanesch, adding the ICSharpCode.SharpZipLib library has indeed solved my problem with corrupted xlsx files.

Created Unassigned: Conditional formats in xlsx not shown in LibreOffice calc [13375]
Adding conditional formats (using the example file of NPOI 2.1.3) to an xlsx spreadsheet are missing when the file is opened in LibreOffice Calc. Excel opens correctly after "repairing" the file. If the "repaired" file is saved from excel the formats also appear in Calc.
Some digging in the xml data revealed that NPOI sets all "priority" fields in the cfRule entry of the sheet to "0".
It seems there is a line missing in the sheet.cs module .\ooxml\OpenXmlFormats\Speradsheet\Sheet.cs which copies the CT_CFRule fields to the XML file. Adding the priority field in the Set function fixes the issue.
public void Set(CT_CfRule src)
{
this.formula = src.formula;
this.stopIfTrue = src.stopIfTrue;
this.bottom = src.bottom;
this.percent = src.percent;
this.dxfId = src.dxfId;
// added priority field transfer copy
this.priority = src.priority;

New Post: How to igrone cell inconsistent formula error
Hi,
I am using NPOI V 2.0.6.0 to create XSSFWorkbook. For some cells I am setting Formulas which are kinda inconsistent. So is there a way I can ignore the cell error from code?

Your help is greatly appreciated

Created Unassigned: NPOI interprets date formats differently [13398]
I have an _xlsx_ file with several dates.
One cell appears in Excel 2007 (configured as Spanish, Spain, international) as "01/02/2003 4:05" (that is 1st February 2003). The cell format appears as "dd/mm/aaaa h:mm" in Excel. NPOI gets "2/1/03 4:05".
What appears as "01/12/2001" is read by NPOI as "12/1/01". The cell format is "*14/03/2001" in Excel.
What appears as "23:05:00" is read by NPOI as "11:05:00 ". The cell format is "*13:30:55" in Excel.
The code I use to read the file is:
```
DataFormatter dataFormatter= new DataFormatter(CultureInfo.CurrentCulture); // es-ES
// ...
object cellValue= dataFormatter.FormatCellValue(ijCell);
```
In some cases, I see that NPOI is applying the predefined formats from _NPOI.SS.UserModel.BuiltinFormats_, but they seem not to match what Spanish Excel does.
Is there a way to make NPOI use the same format as Spanish Excel?

I made some changes which allow workbook to save information correctly.
__Styles.cs__
```
// why to set single line as as default option ?
public CT_UnderlineProperty()
{
// this.valField = ST_UnderlineValues.single;
this.valField = ST_UnderlineValues.none;
}
public ST_UnderlineValues val
{
get
{
// return (null == valField) ? ST_UnderlineValues.single : (ST_UnderlineValues)this.valField;
return (null == valField) ? ST_UnderlineValues.none : (ST_UnderlineValues)this.valField;
}
set
{
this.valField = value;
}
}
```
