Created Unassigned: Deleting row from table resizes table incorrectly [9418]

I am greatly enjoying ClosedXml but have run into an issue when deleting a row from a table.

The issue seems to be that while the row indeed is deleted, the last (undeleted) row of the table ends up *outside* the table. That is, if I have a table with 5 rows and then delete row 2 then the resulting table has 3 rows (and not 4) with one bottom row ending out outside the table.

I have attached a simple repro which hopefully shows the issue.

Thanks for a great library and for any assistance!

Created Unassigned: When trying to retrieve value of a formula, ClosedXML throws 'Identifier Expected' Exception [9419]

I am using ClosedXML 0.76.0 to build my application, which handles Excel files.

At one moment, I populate an Excel file with formulas. So far, so good.

The user then gets this file and fills in values concerning the business.

At this moment, I read the calculated values and populate another larger Excel file.

The problem is that when I try reading cells with fomulas, ClosedXML throws "Identifier Expected" exception.

My code is just as follows:

```
1 string formula = row.Cell(i).FormulaA1;

2 object result = workbook.Evaluate(formula);

3 decimal sum += Convert.ToDecimal(result, CultureInfo.InvariantCulture);

```
The exception happens on line 2.

The formula is likely to be _'Indice'!D$5*'URCTS - 210'!G5_ or similar.

Commented Unassigned: Formula evaluation fails with single quotes in worksheet name [9402]

This seems rather fundamental, but after an extensive search I can't seem to find anything related to a problem I'm having.

I'm getting a "Identifier Expected" error when trying to evaluate a formula with the worksheet name in single quotes and containing spaces:
```
string test = "IF('Income & Expense'!H34 <> \"\", 'Income & Expense'!H34, IF('Income & Expense'!H35 <> \"\", 'Income & Expense'!H35, \"\"))";
var val = multiWorkbook.Evaluate(test);
```
I simplified this to:
```
string test = "'Income & Expense'!H34";
```
and get the same "Identifier Expected" error. Removing the single quotes I get "There isn't a worksheet named Expense".

Is there another way to specify spaces in worksheet names? Or is something else going on?
Comments: I am having the same problem with my web application running ClosedXML. Is there possibly any change for this bug to be fixed any time soon?

New Post: IntegerExtension.ToStringLookup not threadsafe?

I get a similar error:
System.ArgumentException: An item with the same key has already been added.
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
at ClosedXML.Excel.XLAddress.GetTrimmedAddress()

at ClosedXML.Excel.XLWorkbook.CreateParts(SpreadsheetDocument document)
at ClosedXML.Excel.XLWorkbook.CreatePackage(String filePath)

I'm using ClosedXML in a web service and the error occurs when there are concurrent calls using the library in separate threads. So it sounds like ClosedXML is not threadsafe but I'm hoping that someone can confirm and if it's possible to make changes to make it threadsafe.

New Post: Export as DataTable

I'm new at ClosedXML and was wondering if there is an easy way to export or save as a datatable or do I just need to loop the rows and columns? There is a great way to load a datatable and I was wondering if it also works in reverse.

Added Information:
I just saw a post about 3 years back and it states to just loop. If noting has changed I go with that.

Thanks

Commented 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.

Regards,
Renaud

Same here using EXCELOPENXML.

It looks like SSRS is putting invalid characts into the XML. It may be related to this EPPlus thread: https://epplus.codeplex.com/workitem/14948

Haven't found a way around yet.

Remember: EXCELOPENXML produces a openXML documents instead of EXCELs old binary format. XLS != XLSX

New Post: AdjustToContent is very slow

February 15, 2015, 8:00 am
$

@DeLeon, can you elaborate on the threading issues?
I can't find no threading in ClosedXml.

I have the same issue with AdjustToContents beeing slow.
We generate a quite large excel sheet. ~20k rows and 50 columns.
For most of our columns the data is quite uniform and adjusting only the top few 100 would be enough, but some of our columns are quite sparse. Mostly empty, but some rows have long strings. If we don't get any strings in the top x rows the width adjustment of that column would be way of.

I'm considering to invest some time to create a pull request with a few performance improvements in this area.
I have a few options that I'm considering.
  1. Move the creation of the graphics object from GraphicsUtils.MeasureString to XLColumn.AdjustToContents and pass the graphics along with the font cache
  2. Create a dictionary from <IXLFontBase, string> to SizeF to cache the size of strings to speed up adjustment when there are lots of duplicates.
  3. Sort the columns by simple string character count and measure the top x% to make it more likely to find the longest columns.
However before I start out I'm curios to hear about the threading issues to make sure I don't mess anything up.

By the way, I can't find any contributor guide lines. Anything special to think about more than to make sure the code looks tidy and the tests are green?
