Dear Benjamin: you are right, the function returns a cell array only if the topmost entity in the JSON string is an array ; if it is instead an object, the function returns a structure. I have updated the description to reflect that.

Rob, the problem is caused by field "526A", which MATLAB cannot accept because field names in MATLAB must start with a letter. I will update the parser to convert invalid field names into acceptable ones.

Rob, have you checked that the argument you pass to parse_json is a string ? The easiest way to convert the contents of a file into a string is to use the function fileread, as in this example :

s = fileread('file.json');
res = parse_json(s);

An alternative parser with faster handling of strings is available at http://www.mathworks.com/matlabcentral/fileexchange/23393
(another JSON Parser). For example, running the example above

companies=parse_json(urlread('http://api.crunchbase.com/v/1/companies.js'));

with it now takes less than 30 seconds.

15 Jan 2012 (another) JSON Parser Parses JSON strings into structures and cell arrays. Author: François Glineur Fang, Qianqian

FYI, an optimized JSON parser, JSONlab, based on this work is available at

http://www.mathworks.com/matlabcentral/fileexchange/33381

It is 10x to 100x faster. A JSON encoder is also provided in JSONlab.

I love the use of nested functions! Well written.

Works like a charm on WeatherBug REST JSON API output of hourly weather forecasts.
