Understanding CSV and JSON Formats

CSV (Comma Separated Values)

CSV is a simple text format where each line represents a row, and values are separated by a delimiter (usually comma). Example:

name,age,city
John,25,New York
Jane,30,London

JSON (JavaScript Object Notation)

JSON represents data as objects with key-value pairs, supporting arrays and nested structures:

[
  {"name": "John", "age": 25, "city": "New York"},
  {"name": "Jane", "age": 30, "city": "London"}
]

Conversion Options Explained

  • Delimiter: Character that separates values in CSV (comma, tab, semicolon, etc.)
  • First row as keys: Uses first CSV row as JSON property names (headers)
  • Format output: Adds indentation and line breaks for readability
