Great code,

but I am having problems with a particular spreadsheet

it has the text “n/a” in a lot of cells and i think maybe the provider may have decided that the particular column is numerical and because “n/a” isnt numerical its getting dropped

any help appreciated

Yeah, it really works.

I’ve tried ExcelDataReader on codeplex, but it had some odd behaviour (some numeric/currency values were converted to date-time strings).

So this OLEDB for OpenXml is really cool.

I’ve tested it on 64 bit. It’s only a matter of oledb providers, but these 2 should be in windows already.

Big thanx!

Now i have to solve:
- opening from stream and not from file
- converting to dataset

Great article… Provided me with good insight when I was consistently getting “External table not in the correct format” error while reading Excel 2007 using Oledb. Thanks guys!

Hi,

I want to retrieve the excel sheet names. i used the above mentioned code. But my excel sheet contains few macros. The below code
System.Data.DataTable dataSet = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);

am getting macros names also. Please help me to retrieve the sheet names alone.

Thanks,
Happy coding

@Antonio Bakula

Unfortunately there is no way to grab an underlying hyperlink from the cell itself. Connecting to an Excel file via OLEDB treats all rows/columns like a flat database. Excel stores hyperlinks and other items in metadata native to the .XLS/.XLSX format. As of this posting the only way to grab an underlying hyperlink is via Interop. Doing a google search will get the results you need for grabbing a hyperlink via Interop.

By the way .. Interop is SLOW (technically speaking it should be), so if you have a lot of records and need to merge data so you can incorporate the links in a personalized DataTable, be prepared to wait …
