Answer 1

If you still cannot connect or get "Microsoft.ACE.OLEDB.12.0 provider is not registered on the local machine" error, you need to download the Microsoft Access Database Engine.

Answer 2

Have you tried it as just

string connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\data\\Proj_Resource Details 20110118.xlsx;Extended Properties=Excel 12.0";

without the []s?

By the way, if you are not escaping anything, just use @

string connString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\data\Proj_Resource Details 20110118.xlsx;Extended Properties=Excel 12.0";

Answer 3

Wrap the whole filename in quotes, but because this is a literal string use \" to escape them:

string connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\"D:\\data\\Proj_Resource Details 20110118.xlsx\";Extended Properties=Excel 12.0";

Answer 4

string connString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\"**D:\data\Proj_Resource Details 20110118.xlsx\";**Extended Properties=Excel 12.0";
