I know this is late to the party and most likely going to be the last comment anyone reads, but this can be done quite simply in MS Access 2016 - by someone like myself who has no more than 4 days experience in databasing overall and no experience with writing custom Macro's or VB Script (using only what is native to MS Access).
Here's how I did it.
Scenario - Split Form (Form + Datasheet).
Extra Recommendations:
It pays to be across all properties of every object type in your database, as a change in a field property can cause unpredictable erratic effects, which take ages to figure out why it happened and how to stop it from happening again, whilst delivering your desired outcome.
Me.Requery in your VBA script after every necessary event and also in your main form (generally the 'After Update' event is used most), and be wary that too many Me.Requery's (in unnecessary events) can also be detrimental - so too much of a good thing can be a bad thing.
Bottom Line Up Front - Modify the format of your query that is to be exported/printed.
In 'Design View' of the query you are concerned with, ensure that the fields are in the order you need them outputted in first as this is exactly how the macro will present them for export/print (example could be "Australia" then "Northern Territory" then "Town's In The Northern Half Of The State" then "Darwin" then "Suburbs In The Northern Half Of City").
Switch to 'DataSheet View' in the same query and use the top left folded over triangle looking thingy to highlight the entire data set then right click that same triangle to present an options menu. Select 'Row Height' and type in "15" (default row height in Excel).
Deselect the entire spreadsheet and this time select every column (left click the left most column, hold shift button, scroll over to the right to the far end of the data set and click the last column) and then right click one of the highlighted columns to present another menu. Select 'Field Width' and within that new pop-up menu select 'Best Fit' and then 'OK'.
(Optional - not sure if this helps or hinders but I did it for my purpose) With the columns still selected right click one of the highlighted columns again and select 'Freeze Fields'.
My scenario had buttons with macros configured to run filtered reports so I was able to check this by simply clicking any of those buttons and seeing the report formatting, which it held true to the work I had just done. I exported using another button with a macro that exports to Excel with 'Print Formatting' selected (my main form also had the datasheet view as the only thing that could be printed and was also set in 'Print' formatting.
The Excel spreadsheet opened with all row heights and column widths in a way that I could read every field/record with perfect ease and without extra modification.
This also worked for cascaded combo boxes, with the export only outputting the 'drilled down/filtered' datasheet records, in a format that required no further modifications.
Hope this helps someone, as its saved my hide! :)
