Write excel file on server to transfer to user, including colours


I want to export a large amount of data to an excel file (30,000 plus). This is no problem. The problem is that, one of the columns needs to be coloured green according to the data within it.

For example, the colour contains percentages, and when the percentage is over 70%, then the cell needs to be green.

I can do this easily using a Datagrid/Gridview. However, because of the amount of data, my server is crashing with a SystemOutOfMemory exception.

What I would like to do is use a tool to write the data to an excel file, and then transfer the file. Is this possible?

Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

What are other requirements  ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.


While Importing Excel 2007 file to Datatable - headerrow problem


Hi there,


I am trying to simply extract an excel data from an uploaded file an put it into a datatable. In this case the excel file has 3 rows but when I fill the datatable I only see row count of 2.

I tried changing HDR:NO; to HDR:YES and vice versa, but no luck. 

What am I doing wrong? (Note: the excel file cannot have a  headerrow)


string connstr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pFilePath + ";Extended Properties=\"Excel 12.0;IMEX=1;HDR:NO;\"";
            OleDbConnection conn = new OleDbConnection(connstr);
            DataTable dtTables = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);
            string strTablename = dtTables.Rows[0]["TABLE_NAME"].ToString();
            string strSQL = "SELECT * FROM [" + strTablename + "]";

            OleDbCommand cmd = new OleDbCommand(strSQL, conn);

            DataTable dt = new DataTable();
            OleDbDataAdapter da = new OleDbDataAdapter(cmd);
            //At this point row count=2 which doesn't make sense

Returning datas from two excel file



I used the below code to return the datas from one excel file. My question is if i suppose need to get the records from morethan one excel file using joins, how it is possible.

        OleDbConnection oledbConn = new OleDbConnection(connString);

            // Create OleDbCommand object and select data from worksheet Sheet1
            OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", oledbConn);
            // Create new OleDbDataAdapter 
            OleDbDataAdapter oleda = new OleDbDataAdapter();
            oleda.SelectCommand = cmd;
            // Create a DataSet which will hold the data extracted from the worksheet.
            DataSet ds = new DataSet();
            // Fill the DataSet from the data extracted from the worksheet.
            oleda.Fill(ds, "Employees");

Excel file not showing in search results

We have a strange issue. I have one Excel document (or at least one that I am aware of) that will not show up in search results for content within the document. I can find the document by title just fine, but when I search for words within the document I do not see it. The document was originally a 2003 Excel document and was recently converted to 2007. Other than that there isn't really anything unusual about it (some formatting stuff, but mainly just background colors and whatnot, nothing fancy). The crawl log shows the document was crawled without error. Anyone know anything else I can check on?

The excel file was created using Excel 2003.
Any idea how to fix it?
Thank you very much,
