JSON Schema Generator Python

Question

I am using this resource to generate the schema https://github.com/wolverdude/GenSON/

I have the below JSON File

{
 'name':'Sam',
},
{
 'name':'Jack',
}

so on ...

I am wondering how to iterate over a large JSON file. I want to parse each JSON file and pass it to GENSON to generate schema

{
  "$schema": "http://json-schema.org/schema#",
  "type": "object",
  "properties": {
     "name": {
       "type": [
        "string"
      ]
   }
},
  "required": [
    "name"
  ]
}

you question is not clear. What do you want exactly? Iterate over the second json for what? — Lu Chinke, May 08 '19 at 15:14
I have a stream of JSON. I want to iterate over each JSON object so that I can generate schema using GENSON — sampippin, May 08 '19 at 15:16

I think you should:

import json
from genson import SchemaBuilder

builder = SchemaBuilder()
with open(filename, 'r') as f:
    datastore = json.load(f)
    builder.add_object(datastore )

builder.to_schema()

Where filename is your file path.

File size is too big (around 1GB) I was wondering if there is a memory efficient way to this? – sampippin May 08 '19 at 15:26
