reading an combining excel files
显示 更早的评论
Hi everyone,
I have a folder with excel files with I would all like to load in and combine. Is this a possibility? I want to prevent loading them in one-by-one and then combining them one-by-one since it contains around a 100 excel files with all just one row of heading and one row of data.

There are a few different ways to get this task done. One of them is this one if your data files have the same number of numerical data sets (there is just one row of data in each file you stated):
FILE = fullfile('C:\Users\...', '*.xlsx'); % Directory where the files are residing.
LIST = dir(FILE);
N = length(LIST); % N number of files
Ncols = ??? % Ncols how many columns of data in
D = zeros(N, Ncols);
for ii = 1 : N
FFName = fullfile(LIST(ii).folder, LIST(ii).name);
DATA = readmatrix(FFName);
D(ii, :) = DATA; % NOW D contains all data from 100 files
end

Hi,
From my understanding, you can use the function spreadsheetDatastore to manage and import the data when you have data stored across multiple spreadsheet files.
Here is an example from documentation:
