Creating structs with variable names of read-in data parameter names

I'm reading large excel file with both headers and data values. I've attached a sample.

I have many 'Days' (Day 1, Day 2, Day 3 etc.) of data. On any given 'Day,' I may have a few 'tests' (test1, test2, test3 etc.). Within those tests I have a couple variances, like stage, or if the column contains input data or measured values.

I have several columns of data correpsoinding Day 1, Day 2 and so on. What I want is to create a struct for each 'Day' and test whose variable names are the names of the day and test number, so I could say

M = Day1.test1

or something like that. The end goal is to write a csv file for each individual test. I was thinking structs would be a good way to do that, but if someone has a better suggestion I would gladly take it. Thanks

This is not clear, give a short example

[Mark]

   days = [ 'Day 1' 'Day 2' 'Day 3' ]; 
DayTestNumber = [ test1, test2, test3];
for i = 1:3
   variableDay = days(i)
   for j = 1:3
       variableTest = DayTestNumber(j)
   end
   variableDay.variableTest.time = stuff
   variableDay.variableTest.data = moreStuff
end

I want to write

Day1.test1

or

Day1.test3

or

Day2.test2

etc and be able to access the right data, where the 'stuff' is different for each day and test.

Also see the sample .txt I attached to get a picture of what I'm workin with.

Dynamic field names can get you everything except for the outer structure name, but you could toss everything into one container struct.

M = alldays.(DayField).(TestField)

Fantastic. Thank you much. Any idea why you can't do this for the outer structure name? Seems a bit funky...
