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.

Thanks Joel, I thought maybe there would be an easy workaround you could point me to. But the new file solves the issue, it is faster by some magnitude. In any case, thanks for your work.

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.

Hallo Joel,

thanks for the work!

I'm trying to query the Chruchbase API and it seems to work fine. However, it takes ages for some queries to get parsed, e.g. I quit

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

after 1 hour. The profiler says that

json(1) = []; in parse_json>parse_string
json(1) = []; in parse_json>parse_object

make up about 90 % of the computational cost. Is there some easy way around this?

Best,
Patrick
