2. C# Read Excel File Xlsx

Ndruha 13-Oct-17 4:5813-Oct-17 4:58Hi. Thank you for your work. Unfortunately it doen't work with some of the xlsx files. HiI finally found the way to read Defined Names.

To read Excel data, you can open the Excel application and use it as a server to manipulate Excel workbooks. First open the Add References dialog. On the COM tab, select “Microsoft Excel 14.0 Object Library” (or whatever version you have installed on your system). Add the following using statement to make working with the Excel namespace easier. In this example, we will fill some data into a datatable from excel application. We created this DataTable example using with COM Object ( C# Read Excel File into DataTable without OleDb) Berfore the creating codes, here is the examples screenshot.

I made some changes in the code, basically I read and serialize the file xl/workbook.xml, which contains Defined Names.Also I found an error when reading some xslt files and adapted Cell.CellReference (ColumnIndex to Cell reference) to allow relating Defined Names with Cells, since ColumnIndex is still accessible due to its public modifier.So now, plus having the Defined Names we have the complete workbook.xml data which contains additional info in the new property Workbook.WorkbookDefinitionI posted the complete code on github:Thank youKind regardsLeonardo. Member 12077258 7-Feb-16 7:567-Feb-16 7:56HiThanks for posting this it is very helpful for what I am working on. I was just curious if you have found a solution for the following issue. I have been stuck on this for a long time and my attempts to adapt the code to this situation have failed.When reading an excel sheet with cells that have character level formatting, the text value returns null for that cell. Looking into the sharedstrings.xml I found that the ' elements that return null during the deserialization of the xml file are the ones that contain two ' elements within the ' element to account for separately formatted text within the same cell.Is this a known issue?Any direction would be greatly appreciated.Thanks.

You can have a check on the following sample, it illustrates how to import data from data table to excel and export data from excel to data table using an external 3rd party library(free spire.xls in this sample), the code is very simple.I already tried the following code and it works fine. //Load the Excel fileWorkbook workbook = new Workbook;workbook.LoadFromFile(@'Input.xlsx');//Get the first worksheetWorksheet sheet = workbook.Worksheets0;//Export data to data tableDataTable dt = sheet.ExportDataTable. There is an in to check out.Important points (as per the article, all use OleDb data provider). In the connection string specify HDR=No to exclude the headers. When doing so the DataTable column names will be F1, F2, F3,F4,F5 but you can alias them e.g. SELECT F1 As A, F2 As C etc. You may need to add IMEX (mentioned in the article) for data to come thru properly, there are several values which are explained in the article.

If you want only want the first three columns then do SELECT F1 As A, F2 As B, F3 As C. Note the connection string will be different between.xls and.xlsxPlease remember to mark the replies as answers if they help and unmark them if they provide no help, this will help others who are looking for solutions to the same or similar problem.
