csv2struct

reads Excel's files stored in .csv or .xls file formats and stores results as a struct

Description

CSV2STRUCT reads Excel's files stored in .xls or .csv file formats and stores results as a struct.

DESCRIPTION
The Excel file is assumed to have a single header row. The output struct will have a field for each column and the field name will be based on the column name read from the header.

Unlike csvread, csv2struct is able to read files with both text and number fields. Unlike xlsread, csv2struct is able to read .csv files with more than 65536 rows.

Utility was originally written for reading large .csv files.

Have only just started playing with this script, but so far it seems to be another truly excellent utility from Jaroslaw Tuszynski.

Does everything it says. Columns with text come out as cells. Columns with numbers come out as matrices. And all of them are stored in a structure such that you can reference them by the name of the column header.

This seems to me far superior to anything else I've found either here on FEX, or built in to Matlab (though I'm only running R2007a at the moment, so I can't comment on newer releases).

Will post an update if I come across any problems further down the line, but on present experience I highly recommend this script!

Really useful submission!

Works nicely on .xls, but doesn't seem to work on .csv for me... In particular, xlsread (which csv2struct relies on even for .csv) doesn't seem happy with .csv files at all; I'm not sure if this is a platform issue (xlsread under Windows can be more advanced than xlsread under Linux, which I'm currently using) or a version issue (I'm currently using R2006a). Any ideas? (It's easy enough to convert csv to xls, and then use it, but csv is more widely compatible than xls for other software...)

It's really useful.
just a minor error.

line 78: name = char('A'-1+c);
instead of
    name = char('A'-1+i);

@Ged: "***If your system does not have Excel for Windows installed, or MATLAB cannot access the COM server, xlsread operates in basic mode. In this mode, xlsread only reads XLS files.***"

Yeah this is unfortunate - would seem to mean that this script will only work on windows machines. Not the author's fault, but down-rated accordingly =/

it didn't work well for me when I passed a csv file which size exceeded 2^16.
