I have excel data that is pretty big (10000x63) and unorganised. I have attached the sample data file here (sample.xlsx).
This data is converted from a pdf to excel so there are a lot of issues. I will highlight some of them here.
Some key things to note about data
  1. There are strings and numbers and I would like to keep them both organised.
  2. After every 200-250 rows, the table header labels keep repeating which I would like to remove
  3. Whenever the table header repeats, the columns shift left or right (sometimes upto 5 or 6 columns)
  4. There is one column "Code" which has both strings(1,2) and numbers(2).
  5. There are some cells where there is no data or "------".
  6. There are some texts on the top and bottom of the table (legends etc) which I would like to remove.
I would like the data to look like this one big simple list (it took me 4 hours to make this). I would like to automate it as I have many excel files of similar dimensions(10000x63).
Additionally I would like to know if there's a better way to organise this data other than matlab?
Thank you well in advance for your help. I am still learning matlab so any help would mean a lot!

I found it easier to work with the file if I first exported the data to a csv file in Excel.
While this works well for this file, I'm not sure how well it will work across all your files.
% Had to manually determine the number of headerlines.
% Ideally, this is constant across all your files.
opts = detectImportOptions('Sample.csv','NumHeaderLines',6,'VariableNamingRule','preserve','TextType','string','TreatAsMissing',"---");
opts.ConsecutiveDelimitersRule = 'join';
myT = readtable('Sample.csv',opts)
myT = 53x62 table

I am not certain what result you want.
This approach first eliminated columns that are completely empty, then eliminates the empty rows from that result, finds the values in column 1 that are 'ID', and then segments the remaining rows by those results into separate cell arrays.
