You can use a macro. First, create all the queries. Next, open the macro window. In the first line put Setwarnings, set to NO, this will turn off warning messages that appear on the screen that require you to click and OK or Cancel.
Next line put Hourglass YES.
On each of the next lines put TransferSpreadsheet and fill out the dialog box with the correct settings for your export on each line.
On the last two lines, Setwarnings, set to YES to turn them back on, Hourglass, set to NO to turn hourglass off when macro finishes.
If you want to debug your macro, turn Setwarnings in the first line ON so you can review any messages. There is a catch in all this - if the Excel file you are exporting already exists, Access will append the new export to a new worksheet in the file.
If you want to automate it in code, look at the TransferSpreadsheet method in the help file. The example in the help file shows how to do this. Using code, you can solve the problem of the existing file by using a KILL [filename] command to kill the old stuff before you create the new.
