Does textscan not work properly/needs some other inputs in R2013b?

I use textscan to read data from a large number of .csv files. The script works perfectly well on my work laptop (64-bit, R2010a), but fails to read any data when I use the same script on my workstation (64-bit, R2013b).

The red text I see on R2013b: Error using textscan Mismatch between file and format string. Trouble reading number from file (row 1u, field 9u).

Command I am using:

    Data = textscan( fid, DataFormat, NumberOfRows, 'delimiter', ',' ...
    , 'treatAsEmpty', {'NA', 'Unknown'}, 'headerlines', NumOfHeaderlines ...
    , 'ReturnOnError', false)

Please advise.

You may want to show us your format string. And possibly attach one of the files where it is failing.

[per isakson]

"(row 1u, field 9u)" &nbsp Is that really a "u"? Encoding problem?

"Mismatch between file and format string" &nbsp What is the value of fid?

I'll test with R2013b if you attach a data-file

Apologies! I had forgotten to attach the file.

I used this: fid = fopen('textscan_temp.xlsx'); data = textscan(fid, '%d %d %d %s').

I got empty cell array.
