How Tab Lab Converts JSON to Tabular Data

Tab Lab converts JSON data into tabular format for easier analysis. Here's how different JSON structures are transformed:

Simple Objects

Basic JSON objects are converted to single-row tables:

JSON Input:

json

{
  "name": "John Smith",
  "age": 30,
  "isStudent": false,
  "gpa": 3.8
}

Table Output:

name	age	isStudent	gpa
John Smith	30	false	3.8

Nested Objects

Nested objects are flattened with dot notation:

JSON Input:

json

{
  "person": {
    "name": "Alice Johnson",
    "contact": {
      "email": "alice@example.com",
      "phone": "123-456-7890"
    }
  }
}

Table Output:

person.name	person.contact.email	person.contact.phone
Alice Johnson	alice@example.com	123-456-7890

Arrays of Objects

Arrays of objects become multiple rows:

JSON Input:

json

{
  "users": [
    {"id": 1, "name": "John", "role": "admin"},
    {"id": 2, "name": "Jane", "role": "user"}
  ]
}

Table Output:

users.id	users.name	users.role
1	John	admin
2	Jane	user

Mixed Types

Different data types are preserved in the conversion:

JSON Input:

json

{
  "string": "Hello World",
  "number": 42,
  "float": 3.14,
  "boolean": true,
  "null": null,
  "array": [1, 2, 3],
  "object": {"key": "value"}
}

Table Output:

string	number	float	boolean	null	array	object.key
Hello World	42	3.14	true	null	[1, 2, 3]	value

How to convert JSON to CSV in Python

First, we need to install pandas

pip install pandas

Then we can load the json file into a dataframe

df = pd.read_json('path/to/file.json')

Finally, we can export the dataframe to the csv format

df.to_csv('/path/to/file.csv', index=False)
