Within the strict context of vanilla google sheets, I would like to check if there is a way to dynamically address a Sheet by name.
For instance, if one of my sheets is named "foo's great", I can access it in a formula by the following:
=COUNT('foo''s great'!A2:A500)
Now, let's say I want to stop hardcode the sheet name and want to use a cell containing that sheet name, resolve it to the sheet name, and do my things.
Something along those lines:
=COUNT(EVALUATE_RESOLVE(Z1)!A2:A500)
Where the cell Z1 contains a String, resolving to an existing sheet name within the workbook.
