For the existingFile parameter, you can pass a FileInfo object containing the path to your excel file or a stream containing the excel data. There are quite a many overloads of the constructor. I usually use these two.

The number of rows can be found by saying 'worksheet.Dimension.End.Row'. The number of columns can found in a similar way.

Because the underlying XmlDocument is visible the following will work: private String getMaximumRowNumber(ExcelWorksheet worksheet) { XPathNavigator nav = worksheet.WorksheetXml.CreateNavigator(); XPathExpression exp = nav.Compile("//*[name()='row']/@r"); exp.AddSort("../@r", XmlSortOrder.Descending, XmlCaseOrder.None, "", XmlDataType.Number); XmlNode node = nav.SelectSingleNode(exp).UnderlyingObject as XmlNode; return node.InnerText; } private String getMaximumCellColumn(ExcelWorksheet worksheet) { XPathNavigator nav = worksheet.WorksheetXml.CreateNavigator(); XPathExpression exp = nav.Compile("//*[name()='c']/@colNumber"); exp.AddSort("../@colNumber", XmlSortOrder.Descending, XmlCaseOrder.None, "", XmlDataType.Number); XmlNode node = nav.SelectSingleNode(exp).UnderlyingObject as XmlNode; return node.InnerText; }

Why no one answered this question ? I feel disappointed now when I want to iterate through rows... that function is so obvious and everyone use it I guess. Well time to look for something else.

I regret wasting my time with this package because this is how I feel after realizing that there is no method for getting the number of rows or the used range. In order to parse data, you have to know in advance the number of rows and columns apparently.

Bump! How can we iterate through a worksheet if we don't know the number of rows/columns?

I have some forumlae that have a dependancy on other formulaic cells. Despite calling RemoveValue() on these cells, they are not calculated on file open. Any one else?

Looks like there is a bug in ExcelPackage.cs file. Line 21 if (newFile.Exists) return false even though file exist. I think It should be if (File.Exists(newFile.FullName)) { this._package = System.IO.Packaging.Package.Open(newFile.FullName, FileMode.Open, FileAccess.ReadWrite); } instead. Please, let me know if you have any question. Thanks for creating ExcelPackage.dll. Great work!!!!!!
