CSV to JSON

Data comes in many forms. Two popular formats are CSV and JSON. Understanding them is important for developers and data analysts.

What is CSV?

CSV stands for Comma-Separated Values. It is a simple file format used to store tabular data. Each line in a CSV file represents a row of data. Commas separate each value in the row.

Key Features Of Csv

• Easy to create and read.
• Widely supported by many applications.
• Best for simple data structures.

What is JSON?

JSON stands for JavaScript Object Notation. It is a lightweight data interchange format. JSON is easy to read and write for humans and machines.

Key Features Of Json

• Supports nested data structures.
• Uses key-value pairs for data representation.
• More suitable for complex data.

with open('data.csv', mode='r') as csv_file:
    csv_reader = csv.DictReader(csv_file)
    data = list(csv_reader)

# Write JSON file
with open('data.json', mode='w') as json_file:
    json.dump(data, json_file, indent=4)
    

Method 2: Using Online Tools

Many online tools can convert CSV to JSON easily. Here are some popular ones:

• ConvertCSV.com
