The txt file I exported from the analysis software contains commas and text and numbers (as shown in the figure below). This prevents me from directly using load data
The above txt file can be imported into excel using [Data Analysis Wizard] to split it into multiple cells, but I have thousands of these files, I can’t extract data from excel one by one, I want to use more automated Way to extract.

clc;
clear all;
% Specify the folder where the files live.
myFolder = 'C:\Users\yourUserName\Documents\My Pictures';
% Check to make sure that folder actually exists. Warn user if it doesn't.
if ~isfolder(myFolder)
errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
uiwait(warndlg(errorMessage));
myFolder = uigetdir(); % Ask for a new one.
if myFolder == 0
% User clicked Cancel
return;
end
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '**/*.txt'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
num_files = length(theFiles);
t = cell(num_files,1);
for k = 1 : num_files
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
t{k} = readtable(fullFileName);
end
