I'm attempting to format a cell in excel to the currency format. So I go into excel, record a macro of me converting an ordinary cell to a currency format, take a look at the vb script and see that it outputs the following:
NumberFormat = "$ #,##0.00"
So i take that format and paste it into my code, it works to the extent that im getting the currency character before the values in my excel sheet. However, the format of the cell is still a number and excel places a little green triangle at the bottom left of the cell informing me that the format is incorrect (which it is, cos its supposed to be currency, but its set to number) is there any way in c# to actually set the cell to a "Currency" format?
thanks
The range object has a "Style" property... the intelisense metadata says that it is "Returns an object you can use" only but you can also just set the Style with that property. To get the built-in "Currency" style, use the "Styles" property of (for instance) a Workbook object.
Example:
using Excel = Microsoft.Office.Interop.Excel;
...
var excel = new Excel.Application();
var wb = excel.Workbooks.Add();
var sheet = (Excel.Worksheet)wb.Sheets[1];
((Excel.Range)sheet.Cells[3, 4]).Style = wb.Styles["Currency"];
In fact you can just set it to the string "Currency" which may be what Charles was suggesting.
((Excel.Range)sheet.Cells[3, 4]).Style = "Currency";
Ok i tried many that codes and i found this works better than other on any language/regional settings.
numberFormat = #"_-[$$-409]* #,##0.00_ ;_-[$$-409]* -#,##0.00 ;_-[$$-409]* ""-""??_ ;_-#_ ";
Not sure I understand your question:In Excel all numeric values including currency, integers and date/time are held as floating-point doubles. The Format of a value only controls how it is presented in the rendering (visible) layer. The green triangle tests do not include tests for formatting. Is the problem that you are creating a text value rather than a numeric value?

I have trouble creating cells in excel using openXml. If I use Datatype Number I get a warning when opening the excel "We found a problem with some content in file.xlsx. Do you want us to try to recover as much as we can?"
And if I use datatype string I get the warning inside excel.
This is the code I use...
Cell newCell = new Cell() { CellReference = cellId };
row.InsertBefore(newCell, refCell);
newCell.CellValue = new CellValue(value);
newCell.DataType = new EnumValue<CellValues>(CellValues.String); // Generate warnings since number is type text in cell
//newCell.DataType = new EnumValue<CellValues>(CellValues.Number); // Generate error when open the file
newCell.StyleIndex = 0;
UPDATE, If I add a decimal value like 10.2 I get this error, but if I add just 10 as value without any decimals there is no error at all. So how can I add decimals without getting this error?
This is probably an issue with localization. The ToString() method of Decimal uses your current locale for the output. In your case that's likely a comma. OpenXML wants dots afaik.
You can force the locale to the ToString() method as shown in the examples here.
e.g.
value.ToString(CultureInfo.CreateSpecificCulture("en-US"));
edit. It could be that you need to do more, and convert it to scientific notation, as described here.
Edit2: Note the existence of OpenXML.DecimalValue
Is there any way to control whether a number displays in scientific notation using the EPPlus library to generate an Excel file in C#?
worksheet.Cells[row, col].Value = someValue; //example value: 0.0000152691
worksheet.Cells[row, col].StyleName = RegularCenterAlign;
worksheet.Cells[row, col].Style.Numberformat.Format = "WHAT DO I PUT HERE???";
I tried "0.00e0" for the format and that causes excel to throw an error:
I didn't see it in the documentation but if you look in Excel at the formatting options, scientific notation is available, so you'd think EPPlus has a string code we could use for this.
What seems to be happening now is Excel is making its own determination about whether to format a given number in scientific notation. The same code inserted all of the numbers in the following screenshot. No format was specified but you can see that last one did not use scientific notation.
Use:
ws.Cells["A1"].Style.Numberformat.Format = "0E+00";
You can add the number of decimals with something like:
ws.Cells["A1"].Style.Numberformat.Format = "0.0000E+00";
Don't forget that your value should be numeric. This value will be formatted:
ws.Cells["A1"].Value = 0.0000152691;
this one won't:
ws.Cells["A1"].Value = "0.0000152691";
i am aware of the floating point inaccurrancy, this is just how to get the correct text FORMAT!! by openxml from the xlsx and show the value like excel does. I am not able to edit the excel file and change the format or something like that, because of some reasons.
while working with numbers formated as numbers everything runs fine
formatted as text or general, the number 0.813 is saved as 0.812999.., excel shows it correct!, but via openxml i can't get the used format (0.000), anyone an idea to get the format?
maybe this is a standard format, not saved and choosen by other values?
finally I am using the ugly solution to get rid of this ..
if the cellFormat NumberFormatId is 2 I try to parse the value to double and then to string with two decimals
double.Parse(displayedValue).ToString("0.00");
not my desired solution, but for the moment this works .. of course also with all other unit tests
I am trying to write to Excel using Excel Interop. One of my column will have a very numeric value (44 digits).
After checking similar posts in the internet, I tried setting the NumberFormat.
worksheet.Cells[i, j].NumberFormat = "#"; and worksheet.Cells[i, j].NumberFormat = "#";
But it still shows the values in format- ######... so on.. I tried expanding the columns too but that did not work. However, this worked for some of my other column where I have numeric values in 14 digits.
Any help? Please let me know if I can provide more details.
There is a 15 digit limit in Excel unfortunately
for cells use cells["A:A"].numberFormat = "#";
for columns use cells[0, 2].EntireColumn.NumberFormat = "#";
If showing the data in text is ok , then set the cell format to TEXT.
I´m trying to apply conditional format to Excel using EPPLUS so that a range of cells is filled with red color if the value is negative.
I try this code that if the value of the cell is bigger that the value of the next cell, that cell is filled with red
ExcelAddress _formatRangeAddress = new ExcelAddress("J2:J"+(listaMargenes.Count+2));
string _statement="IF(OFFSET(J3,0,-1)-J3>0,1,0)";
var _cond4 = hoja.ConditionalFormatting.AddExpression(_formatRangeAddress);
_cond4.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
_cond4.Style.Fill.BackgroundColor.Color = System.Drawing.Color.Red;
_cond4.Formula = _statement;
this Works fine, but if i change:
IF(OFFSET(J3,0,-1)-J3>0,1,0)
by this:
if(J3<0)
does not Works, when opening the Excel says there is corrupted data.
any idea of how to write the correct way tu put in red the cells with negative value?
An IF statement in excel does not allow for an optional value_if_true part anymore (I believe in older versions it did): MS IF Documentation
So change it to something like:
string _statement = "if(B3<0, 1)";
