pip install jsonasobj2

Common errors

error ModuleNotFoundError: No module named 'jsonasobj' ↓

cause Installed jsonasobj2 but tried to import 'jsonasobj' (v1).

fix

Use: from jsonasobj2 import JsonObj

error AttributeError: 'JsonObj' object has no attribute 'from_json' ↓

cause Calling from_json() on an instance instead of the class.

fix

Use JsonObj.from_json(json_string) as a class method.

Warnings

deprecated The old jsonasobj library is deprecated. Use jsonasobj2 for new projects. ↓

fix Replace 'import jsonasobj' with 'from jsonasobj2 import JsonObj'.

gotcha JsonObj does not support attribute names that are Python reserved words (e.g., 'class'). Use dict access instead. ↓

fix Use obj['class'] or setattr(obj, 'class', value) if needed.

gotcha JsonObj.from_json() is a class method that returns a new JsonObj. It does not modify the existing instance. ↓

fix Assign the result: obj = JsonObj.from_json(json_string).

Imports

wrong
```
from jsonasobj import JsonObj
```
correct
```
from jsonasobj2 import JsonObj
```
jsonasobj (v1) is a separate library; jsonasobj2 changed the import path.

Quickstart

Create and manipulate JSON objects using attribute access. JsonObj wraps dict and allows dot notation.

from jsonasobj2 import JsonObj

# Create a JsonObj from a dict
data = {'name': 'Alice', 'age': 30}
obj = JsonObj(**data)
print(obj.name)  # Alice
print(obj.as_json())  # '{"name": "Alice", "age": 30}'

# Convert JSON string to JsonObj
json_str = '{"key": "value"}'
obj2 = JsonObj.from_json(json_str)
print(obj2.key)  # value
