New Post: Can this be upgraded or forced to use Open XML SDK 2.5 as that version fixes white space issues
Powerpoint OpenXML whitespace is disappearing
As per the above article, there is an acknowledged bug with white space in Open XML SDK 2.5. Could ClosedXML be upgraded to use 2.5 or is it possible to force it to do so?
Regards, Paul

New Post: Memory problem with ClosedXML
Thanks for the reply, Mitch. This was only a test to assess ClosedXML's memory usage. Looking at XLAddress, XLRow and XLCell I can see that they do not implement IDisposable, and I cannot see how resources are released. From my tests it seems like they keep holding on to a lot of memory even after the using block is exited. I would be keen to read other members' opinions on this.

Commented Issue: Implement Subtotals [7862]
I'm not sure how to upload a file, but here's an example. Let me know if that helps. I think, using the examples of formulas and ranges you gave above, I could make it work for the specific spreadsheet I'm working on. The problem is, I'd have to figure out how to do it for each spreadsheet that uses subtotals. I'd like an easy way to define what field to break on and which columns to add or count or whatever for the subtotal.

New Post: CopyTo seems to be slow while copying a lot of lines.
Since the InsertRowBelow() don't keeps the formats and formulas from the root row, I have to copy from the root row. At last i fill in certain values in to the created rows.
rad = ws.Cell("KontoSaldo").Address.RowNumber;
ws.Row(rad).InsertRowsBelow(2000);
for (int i = 1; i <= 2000r; i++)
{
FillTheRowsWithValues()
It seems that the CopyTo takes longer time for each time it's copying. On my machine it took about 10 sec the first 200 items, when it comes to about 1000 it's only makes about 20 for each 10 sec.

Reopened Issue: Strange values returned, bad value in cell [8535]
I have an excel file that has a formaula getting its values from other tabs. ClosedXml is returning completely different values. This is very strange behaviour. In cell M1210 there is a value (if opened with excel) of -1634290,7 located in TAB [STAGING]. Codeplex is returning the value -180807,44
Woops. Also other values in this column are having the same problem.
This is no good news.

Reopened Issue: "NaN" causes unreadable content error [8403]
I was getting "Excel found unreadable content" errors in some of my workbooks, but I finally tracked down the issue. To reproduce, start a new workbook and add "NaN" to one of the cells:
Dim wb As New XLWorkbook()
Dim ws As IXLWorksheet = wb.Worksheets.Add("Test")
ws.Cell(1, 1).Value = "NaN"
Upon opening the file, you'll get the "unreadable content" error. If you choose to repair the file, it will then show "NaN" in the cell as expected.
I compared the orignial and repaired versions of xl\SharedStrings.xml, and "NaN" wasn't present in the original file - could that have something to do with it?

Reopened Issue: ValueCached shows null after I reopen the ClosedXML saved file [8396]
I faced an issue while trying to recover a formula cell through ValueCache after saving the file through the workbook save method. Following are the steps to reproduce this issue:
1) Open the attached file
2) Its a simple file with the following values
A1 = 8
B1 = 6
C1 = A1 + B1 = 14
3) I use the following code snippet to open the file, read ValueCached from C1, change the value in A1 and save the file. So far its good and the ValueCached shows the correct value which is 14. Now when I run this second time, the ValueCached shows null
var wb = new XLWorkbook(@"c:\fincalc\simple.xlsx");
var ws = wb.Worksheet(1);
var c1 = ws.Cell("C1").ValueCached;
ws.Cell("A1").Value = "10";
wb.Save();
4) Also if I open the same file through excel and try to exit excel, it promts me to save the file even when I have not changed anything. Can you please let me know if the wb.Save() method is missing out something while saving the file?
Thanks in advance for your time.

Hi there,
I found that whenever I do the following:

sheet.Cell(1, 1).Select();
The Excel saved is unreadable by MS Excel. However, if I either don't select the first cell or don't freeze panes, the resultant Excel works fine.

Reopened Issue: Version 68.1 changed order of Rows collection [8373]
I upgraded from version 67.2 to version 68.1 and now the following code does not work.
int rowCount = 0;
XLWorkbook sourceWB = new XLWorkbook(fileLocation);
IXLWorksheet sourceWS = sourceWB.Worksheet(1);
foreach (IXLRow row in sourceWS.Rows())
{
rowCount = row.RowNumber();

}
In version 67.2 and all prior versions this gave me each row in order starting at row 1.
Now in version 68.1 the first row in the list is the row of the cell that was selected when the file was saved.
This breaks all my existing code because I expect the first row in the list to be the header row and I depend on the rows being in order.
Thank you.

Created Unassigned: System.OutOfMemoryException in v0.68.0.10, regression? [8808]
Hello,
In order to improve the speed of reading/writing of Excel files, I have recently updated ClosedXML from v0.64.0.0 to v0.68.0.10.
The kind of Excel file that I deal with is a big file, embedding a lot of VBA code ; I use it as a template, filling only 2 sheets with raw data (number or string, no formula).
The VBA developper improve this file continuously, for some files there was a huge speed difference, but we have arrived in a point where :
- With v0.64.0.0, we have the good results, but it is very slow
- With v0.68.0.10, the memory is increasing and then a "System.OutOfMemoryException" is thrown.
The exception is thrown in the code below
```
public XLWorkbook OpenExcel(MemoryStream xlsStream)
{
return new XLWorkbook(xlsStream, XLEventTracking.Disabled); //RR 13/06/2013 Turning off events
}
```
with v0.64.0.0 the memory is not increasing a lot during this operation (quite stable), but with v0.68.0.10 the memory used is increasing a lot (1 more GB) and then the exception occured.
I try to turn of the events, but it doesn't change anything.
Does anyone else had this issue before?
Thank you very much for your help.

Hello, I have news.
I have done some tests with different versions of ClosedXML between 0.64 and 0.68.0.10, and it prove that the problem of "System.OutOfMemoryException"appear with version 0.65 !
So the gap is much more smaller saying something is wrong between 0.64 and 0.65.
