I have what I believe is a valid JSON dataset.

The contents are:

I am wanting to load this into an ewb dataset.

I have create DataSet1.
If has a DataSetName of "rows" (I think this is correct)
a Name of DataSet1
and 1 column  named PersonID which is a dtInteger field
I then do the following in ewb:


Request.ResponseContent.text is set to the contents above.

When I execute the LoadRows, I get the following error:

Expected "}", instead found "PersonID" at 17
Line: 1

Does that mean that my JSON data is in a wrong format? I am using PHP to return the data and it looks like it's correct JSON data format.

Not sure what I'm doing wrong.

https://jsonlint.com/ says it is valid format, so something more to it. Plenty of examples of the format have been posted to the forums, so have a search. Others have asked about this before, so the answer is here!

OK I see your original post is Integer - so no double quotes on the 1.

It's valid JSON but it's not  valid EWB Dataset JSON.

EWB JSON spec is defined here :


and says JSON is as follows :

{ rows: [ <Row>, <Row>, <Row>, ... ] }

so in your case it should be

Since both ewb and what I was doing are valid JSON format, I just need to coax php into creating the format the way that EWB wants it.

Thanks everyone for your help. I will take it from here and see what I can do.
