McCloud, professor of mathematics To read from an Excel spreadsheet, you’d like to read the lines of text from the spreadsheet. You can then move the file to the appropriate place on your computer. To do this, open the file in your Excel file editor. This is how you can read an Excel spreadsheet in Matlab: If your Excel file is not new, then you will need to create a new file and save it on the computer. You’ll see a caption, with some formatting in the middle. If you’ve never read an Excel file before, then you’ll want to do so in Matlab. % % Import multiple files into one single Matlab variable.How To Read From An Excel File In Matlab “I wanted to read from an excel file in Matlab that required much less work than Excel’s Excel function.” – Manfred Künzle, head of Matlab – If you’re reading from an Excel file from your desktop, you might be interested in this article When you read a file from a spreadsheet, you can read it to the full extent even if you don’t want to. Xlswrite(fullfile(dest_dir,source_files(i).name)) Source_files = dir(fullfile(source_dir, '*.xls')) ĭata = xlsread(fullfile(source_dir,source_files(i).name)) Source_dir = 'C:\Users\xuf\Desktop\Excel Saved PointScans'ĭest_dir = 'C:\Users\xuf\Desktop\Test Folder' How about one of these small scripts? % % Import all excel files in a folder into multiple Matlab variables. it's something to think about if you want to search for Excel files that aren't in the working directory. If you are finding files in the current working directory, then the fullfile stuff isn't required. SearchString = fullfile(directory, '*.xlsx') įileName = fullfile(directory, d(idx).name) %// Get the file name %// Create absolute path to search for Excel files You can use fullfile to help you do that: directory = '/put/my/directory/here' %// Place directory to search for Excel files here As such, to successfully open up files, you'll need to piece together the directory you specified plus the relevant filename local to that directory. Bear in mind that when using dir, it finds the files with respect to the input directory you specified. If on the off-chance you are wanting to find Excel files that are not in the current working directory, you can do something like below. Out = xlsread(fileName) %// Read the Excel file Therefore, you'd have to access each name field for each file individually and use this to finally open up your files.įor example, if you wanted the first Excel file, you'd do: fileName = d(1).name įileName would contain the string of the name of the first Excel file, then you can use that to read in the file: out = xlsread(fileName) Īlternatively, if you have more than one Excel file and you want to process them individually, consider putting this inside a loop: d = dir('*.xlsx') %// Find all Excel filesįileName = d(idx).name %// Get the file name This field is the name of each file that matched your query using dir. First, you need to assign the output of dir to something: d = dir('*.xlsx') Īfter this, you'll get a structure array where each element has a name field. You obviously can't use this structure outright, so you'll have to access things within it to get what you need. Each element in this array is information about each file that matched your search query when using dir. You are correct where dir returns a structure array.
