how to convert a .txt file into a .xls file in matlab?

Asked by Cordelle

I suspect that I can actually read the log file data directly into Matlab without conversion. It is just a comma separated variable format(.csv), I believe, and I think it should be accessible to some Matlab input routine.

However,I dont not know the matlab input routine; It would be very helpful if someone can enlighten me on the input routine

thanks in advance, Cordelle

This is not enough information to give a more explicit answer than:

  • Import the file by e.g. importdata or fopen / fscanf.
  • Export the data by xlswrite.

I suggest to add mire details, e.g. the file's contents by editing the original question (not as comment or answer).


When I imported the file using importdata this occured:

data: 3

    textdata: {863x4 cell}

what does this mean? and how can I convert the imported file into an excel file?

That means that data is a structure containg the field "textdata", and that "textdata" contains a cell array (each element of a cell array can be a different type of number, string, or even another array).

That means its a cell in a structure.

You can access data from structures:

and use

If you need editing in between you should do that.

If you are unfamiliar with cell and structures at all in MATLAB, I point you to


Error using load

Number of columns on line 3 of ASCII file


must be the same as previous lines.

How can i correct this issue? (I used the "Load" input routine)

Please do not post explanations like "I used the "Load" input routine", but the corresponding code. This will reduce misunderstandings. Thanks.
