I found in this beta and all toad versions that sql statement included with exported data will be missing if the size of the statement is big and will not fit one cell.
in this case split to multiple cells will solve the issue, and we will not lose the reference SQL.
Sorry, I forgot to reply. This will be fixed in next beta. The problem is that Excel does not allow more than 32K of data in a single cell. So in the next beta, if the SQL Statement is longer than that, Toad put the SQL into the spreadsheet line-by-line instead of all in one cell. It still copy/pastes just fine that way.
