I am just learning SQL so bear with me. I have written sql to pull in the latest information, dowloaded it to an excel file, created pivots etc but I dont want to have to create all the pivots and charts weekly so is there a way to create a connection in Excel and import refreshed data from Toad?
To pull data from an Excel file and import it to a table, rt-click the table in the Schema Browser and choose “Import Data” A wizard will guide you through the process.
You can also send data to Excel from an Oracle table. To do that, rt-click the table in the Schema Browser (or a data grid anywhere in Toad) and choose “Export Data”.
You have a couple options here - and I am not an Excel expert so forgive me if some of my advice is not spot on 
You could create an external data link in Excel to your database and simply refresh the data. So design and test query in toad, then cut/paste that query into Excel external data link so that Excel gets data live from database when you say refresh.
Option #2 - you could use toads app designer to automate the process of running the query and exporting the data to Excel. Too much to explain - go read blogs on toad world that tell about this great feature, show examples - and there are even videos on it.
