JSONtext: JSON Schema?

[SkkjhlSkk9147!!]

James,

I didn't find out "Generate JSON Schema from LV Datatype" at JSONtext library as below. Can you please share where we are able to download it?

[JoGra]

I think there is no generate Schema from Labview date type functionality yet in JSONtext.

I'm currently working on one and will try  release a package soon.

I've needed this too and have made some progress. Would be happy to share/collaborate.

I've created a working repo here: https://github.com/JKISoftware/generate-json-schema-labview

Note that the code is quite simple (not much more complicated than what you're looking at below)

Hi Jim,

Is the repo public?
I can't find it on GitHub..

Cheers

Hi Jim, 

I have made some more progress and could make the repo now public: novatron-fusion/LabVIEW-JSON-Schema-Generator (github.com)

Please have a look! I would be glad for any feedback.

I've also now added a simple Schema Generator to the package:

Hi guys,

I am not very savvy with JSON formats, and I would like to use the 'Validate Against JSON Schema.vi' to show user where a mistake is:

How would I infer the JSON Schema from an already existing JSON file?
I am confused as to how to format the JSON Schema input of the above VI.

Would anyone be able to help me out, please?

Below is an example JSON file content:

There is a generate schema function in the library that should make a basic schema from your JSON.

[JohnatanBravo]

Thanks, wasn't aware of that function, I'll give it a go.
