23 Mar 2009 (another) JSON Parser Parses JSON strings into structures and cell arrays. Author: François Glineur

It is definitely faster than my version.
23 Mar 2009 JSON Parser Parses JSON strings into structures and cells Author: Joel Feenstra

I know that the code is slow, and I made no attempt to make the code fast, just correct. François's version does seem to be faster, so if you need speed (and have a lot of strings), use his.

The Google API limits it to 4 results. You can use the "cursor" information to fetch more results: matlab_results{1}.responseData.cursor

15 Jan 2012 JSON Parser Parses JSON strings into structures and cells Author: Joel Feenstra 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.
22 Nov 2011 JSON Parser Parses JSON strings into structures and cells Author: Joel Feenstra Gao, Boyang

This version cannot deal with JSON file with empty elements. Try http://www.mathworks.com/matlabcentral/fileexchange/23393 instead(also faster).

10 Jan 2011 JSON Parser Parses JSON strings into structures and cells Author: Joel Feenstra Ting, Benjamin

This code does not appear to work if the first { is preceeded by white space (either a space or carriage return).
03 Dec 2010 JSON Parser Parses JSON strings into structures and cells Author: Joel Feenstra Massie, Dan

Works well, despite being a bit slow. Maybe it could be sped up with careful application of "regular expressions." Also, when you use the script, make sure the JSON string is a row vector of chars. Error may occur if string is a column vector of chars.
