In modern software development, REST APIs, MongoDB databases, and cloud services communicate using JSON (JavaScript Object Notation).
However, non-technical stakeholders, financial analysts, and marketing teams work primarily in Microsoft Excel and Google Sheets, requiring tabular CSV (Comma-Separated Values).
Consider this simple JSON array of customer records:
[
{ "id": 101, "name": "Alice Johnson", "role": "Engineer", "salary": 120000 },
{ "id": 102, "name": "Bob Martinez", "role": "Designer", "salary": 105000 }
]
Converted into standardized CSV format:
id,name,role,salary
101,Alice Johnson,Engineer,120000
102,Bob Martinez,Designer,105000
