Commented Unassigned: Compiling ClosedXML with OpenXml V2.5 and .Net 4+ [9145]

OpenXml V2.5 has deprecated SmartTags and also can't be used with with .Net 3.5 builds due some internal dependencies on .Net.4.0.

You can recompile the source to ClosedXml with a reference to the OpenXml SDK V2.5 if you don't need to target .Net 3.5 and if you comment out the line that refers to the SmartTag class


For more info on the SmartTag issue, Google to:

"What's new in the Open XML SDK 2.5 for Office - MSDN - Microsoft"

I'm at the point of testing now so there may be a few other things but even Resharper was happy so it can't be too bad.
Comments: ** Comment from web user: FuriCuri **

Any progress on this? It really bugs me to have package manager to update 20+ packages and then fail to update OpenXML due to ClosedXML and I have to update 10+ manually.

Created Unassigned: Console Application (example) OutOfMemoryException [9188]

There is a high priority report we are creating that keeps getting an OutOfMemoryException.
The exception occurs after the report is created and formatting is applied and while the report is being saved.
It doesn't matter whether it is saved to MemoryStream or to a file.

I created a sample console application that can reproduce the problem.
It is being built with VisualStudio 2010 and uses ClosedXml.dll version 0.69.1.0.
I am running on a Windows 7, 64 bit machine with 8GB memory.

The sample application creates a report out of 164,000 custom objects where each object is identical and contains 19 properties. So the finished Excel file would have 164,000 rows, plus the heading row, and 19 columns. When the console application is run from the command line the user can specify how many rows to create. What is interesting is that sometimes it will throw the OutOfMemoryException and sometimes it will go to completion.

The sample application uses identical data in every row, so Excel's string sharing algorithm should conserve a lot of space, but for some reason ClosedXML keeps bombing out.

A lot of people have mentioned the same problem, but I think this is the first time anyone submitted a sample application to test with.

My workaround is to use Aspose.Cells for .Net in place of ClosedXML and Aspose has no problem saving the file, but ClosedXML throws an exception on the same data.
I much prefer the object model used by ClosedXML, but I have to use Aspose.Cells unless this can be fixed.

Thank you.

Created Unassigned: Read Only setting (?) [9189]

Hello and thank you for the library! I need to read data from an Excel Worksheet and this is totally feasible as long as the file is not open when the following statement is invoked:

var xlWorkBook = new ClosedXML.Excel.XLWorkbook(path);

I understand that when writing in an Excel worksheet it should not be possible to have it opened but what about reading? Is there any "only-reading" setting implemented?

Thank you in advance,

When I try to deal with a file with #REF error, IndexOutOfRangeExceptionexception occurs.

Can't I deal with a file with #REF error?
Without correcting an #REF error, isn't it possible to deal with this file?

Has anyone found a solution to this issue? I have the same problem. I have 1 workbook with several worksheets. One of the worksheets is a template that is copied the number of times needed.

I get the error "An item with the same key has already been added" every time I try to copy a sheet. Changing the name of the copy doesn't help. I don't see where to set a key that it is finding a duplicate.

Anyone else have this problem? Thanks!

I've tried many different methods, but I've had no luck. This is the code I'm using to add the value to the cell
ws.Cell(baseCell).Value = NumberValue;
ws.Cell(baseCell).Style.NumberFormat.SetNumberFormatId(37);
ws.Cell(baseCell).SetDataType(XLCellValues.Number);
I've tried it with several datatypes for "NumberValue" including double, decimal, and float.
I've also tried changing the cell datatype from number to text.

No matter what I do I always get the message. The data I'm using to create the document is all numeric values, so the entire sheet has flags.

New Post: Get Value of Formula using Named Range over Sheets

Assume an Excel File with two Sheets "input" and "calc"
input[a1] is named input1 with value 5,
input[b1] has the formula "=input1"
calc[a1] has the formula "=input1" too.

When i try:

var resultByteArray = File.ReadAllBytes(@"C:\temp\test.xlsx");
        using (var mem2 = new MemoryStream())
        {
            mem2.Write(resultByteArray,0,resultByteArray.Length);
            var wbResult = new XLWorkbook(mem2);
            var res = wbResult.Worksheet("input").Cell(1, 2).Value;
            var res2 = wbResult.Worksheet("calc").Cell(1,1).Value;
        }
res will contain 5 and res2 will throw an NullReferenceException...

has anyone an idea how to resolve values over sheet-borders?

New Post: Cells.InsertDataTable Time values are recognized as String

Just realized after long tests that when using this code to fill in many cells, the IIS worker process and therefore the memory consumption shoots up to more than 1GB. Maybe because I used a for loop? Can the developer of this library provide inputs on how to help lessen the memory consumption when I use this code?

I could have just used the Cell.InsertDataTable property instead, but due to certain data types (timestamp variables) I need to use a regular expression to match them then a boolean variable for the if-else statement therefore the use of a for loop.

Much appreciated! :)

I managed to find the solution to my query. But I did not utilize anymore the Cell.InsertData property. What I did was to parse each and every cell according to its data type before assigning it to a particular Excel cell.

For the time values, I used regular expressions to match, then used the boolean variable to parse and set the data type of the cell to either TimeSpan or DateTime depending on what I need.

Hi everybody,

I have a column with numbers ( positive and negative ) and I want to add databars to them. when I do this directly in excel, then it generates bars with different colors in both directions ( positive and negative ). when I apply the same formatting using closedXML, the bars only go in the positive direction. I did a bit of digging and I realized that the negative value handling was introduced in Excel 2010. How hard would it be to add support for this feature to closedXML ? is there any intention to add it at all ?

Thank you tons.

ClosedXML has dependency DocumentFormat.OpenXml version 2.0.5022.0 (Open XML SDK 2.0.0 )
