Error with table data

An indexing error occurs when parsing table data using savejson.m

For instance, if one calls the following:

>> j = savejson('test_data', open('census1994.mat'), 'test.json');

you get the following error:

Error using savejson>matlabobject2json (line 444)
You cannot subscript a table using only one subscript. Table subscripting requires both row and variable subscripts.

Error in savejson>obj2json (line 175)
txt=matlabobject2json(name,item,level,varargin{:});

Error in savejson>struct2json (line 285)
txt{end+1}=obj2json(names{e},item(i,j).(names{e}),...

Error in savejson>obj2json (line 171)
txt=struct2json(name,item,level,varargin{:});

Error in savejson (line 140)
json=obj2json(rootname,obj,rootlevel,opt);

I hacked a solution, but I'm not sure if this leads to more issues with other files. See attached.

Cheers,

Your solution works in R2015b, but not in later versions. Moreover, table properties (like RowNames) are not preserved.

sorry @pjkoprowski and @hillsm for the long delay in processing this issue. I patched savejson with Paul's patch, and I also added support for RowNames, but in the current code, neither the VariableNames nor RowNames allows to have space or other non-variable-name strings.

In the future, need to move valid_field() from loadjson to a separate unit and use it to convert Table name fields.
