I am reading data from a large excel file which has got formatted texts. I extract the data to DataTable object through oleDBConnection & GetOleDbSchemaTable. But the extracted data doesn't include any formatted information.
My requirement is, I need to extract only non-Strikethrough texts.
I don't have any issues while reading and everything is perfectly fine. But my extraction should be based on text format in excel which I am unable to find the solution.
Anything to be added in the connectionString which is as follows:
connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + "; Extended Properties=\"Excel 12.0 Xml;HDR=YES;Mode=Read;ReadOnly=True;\"";
Constraints:
Using OleDBConnection - No Interop
Reading to DataTable Object
To the best of my knowledge, you cannot do this with just the ACE driver. That being said, if the constraints are ever lifted, this is the tool to use: http://closedxml.codeplex.com/
You should switch your approach to use open XML. It's .NET, not COM

You have to use "Open Xml" to get to format information if you do not want to use Interop. There is no other choice. There is Biff which I mention only for correctness, but your connection string clearly indicates XML, so Biff is out.
Once you open through "Open Xml" then you can "simulate" reading the range/table/cells like a DataTable.
With your constraints, Only #1 will give you formatting information.
