Created Unassigned: Excel workbook corrupt after saving [9429]
I have an xlsx workbook that is used as a template. Through a ridiculous amount of coding, I have built a library using OpenXML that _almost_ preserves all formatting of the original file after updating the cells with data. Saddened by the reams of code to accomplish this, I turned to ClosedXML and got quite far with a fraction of the code, and was very happy...until I encountered the attached spreadsheet and executed the following code.
```
var workbook = new XLWorkbook(filePath);
workbook.Save();
```
When I opened the file in Excel, I encountered the prompt to recover the contents of the workbook, since Excel found unreadable content. I clicked Yes. Excel flickered a little, and then I am presented with the alert:
> "The workbook cannot be opened or repaired by Microsoft Excel because it is corrupt."
The only hint I have found so far is that the conditional formatting elements in Sheet1.xml are different after saving through ClosedXML than before.
```

Commented Unassigned: While Writing to Excel file its throwing an error "'.', hexadecimal value 0x00, is an invalid character." [9421]
Hi All,
While Writing to Excel File using the ClosedXML facing an issue. Above is the error mentioned into caption which I am getting.
Have attached the Excel File which I am trying to Write by passing the DataSet.
Please Reply ASAP.
Thanks,
Samir.
Comments: This also affects us - can reproduce this with the following: ``` byte[] data; using (var stream = new MemoryStream()) { var wb = new XLWorkbook(); wb.AddWorksheet("Sheet1").FirstCell().SetValue("\u0018"); wb.SaveAs(stream); data = stream.ToArray(); } using (var stream = new MemoryStream(data)) { var wb = new XLWorkbook(stream); Assert.AreEqual("\u0018", wb.Worksheets.First().FirstCell().Value); } ``` The above fails on the call to wb.SaveAs, however even if saved correctly the cell value ends up being read as "_x0018_" and the assert will fail. The [ECMA-376 Specification (part 1)](http://www.ecma-international.org/publications/standards/Ecma-376.htm) says the following under the bstr element > Unicode characters that cannot be directly represented in XML as defined by the XML 1.0 specification, shall be escaped using the Unicode numerical character representation escape character format _xHHHH_, where H represents a hexadecimal character in the character's value. [Example: The Unicode character 8 is not permitted in an XML 1.0 document, so it shall be escaped as _x0008_. end example] To store the literal form of an escape sequence, the initial underscore shall itself be escaped (i.e. stored as _x005F_). [Example: The string literal _x0008_ would be stored as _x005F_x0008_. end example] I had a look at how to fix this with the intention of preparing a pull request, but I'm not familiar enough with OpenXml to identify where this encoding method should be applied - at the minimum it needs to be applied to the shared strings, but it looks like this might also apply to other strings too.

I've had a similar experience to S1 - the business had been complaining about the speed to generate certain excel files (They have over 2 million rows, it going to be slow.) .

New Post: Getting conditional formatting from an existing cell
I haven't done this myself. However, since conditional formatting is stored at the sheet level, try the IXLWorksheet.ConditionalFormats read-only property. Each IXLConditionalFormat in that IEnumerable<IXLConditionalFormat> will have properties that show you which cells participate in the conditional formatting. You should be able to determin if your current cell is one of those.
I hope this helps.

New Post: Getting conditional formatting from an existing cell
That does seem to work for getting the existing conditional formatting, thank you. Unfortunately once I retrieve it, there does not seem to be a way to assign it to a new cell. Am I missing something obvious. I tried adding the range of the new cell to the custom format but that did not seem to work.
