Hello,
I want to load an excel file (shared in attachments) which has numeric and text 'values' in it (text cells are also really important).
I tried using both readtable and xlsread but I never managed to replicate exactly the excel table in matlab (usually the text rows were NaN).
Here is my code.
datapath = '/…/';
d = dir(datapath);
nd = length(dir);
files=dir(fullfile(datapath,'*.xlsx'));
for n=2
file=fullfile(datapath,files(n).name);
int=readtable(file,"ReadVariableNames",true,"VariableNamingRule","preserve");
end
Thanks for your help,
Marine

Table variables cannot contain a mix of numbers and text. In order to preserve the data, we must import each variable as text. detectImportOptions provides more advanced control over how data are read.
https://www.mathworks.com/help/matlab/ref/detectimportoptions.html
opts = detectImportOptions("BH_Model.xlsx",VariableNamesRange="A1:BO1",VariableNamingRule="preserve");
opts.VariableTypes = repmat("string",1,numel(opts.VariableTypes));
Table variables must all have the same number of rows, so extra rows are filled with missing strings.
readtable("BH_Model.xlsx",opts)
ans = 174×67 table
