About CSV to JSON Conversion

CSV (Comma-Separated Values) is a simple file format used to store tabular data. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write.

Common CSV format rules:

  • Each line represents a row of data
  • Columns are separated by commas (or other delimiters)
  • The first row often contains column headers
  • Values containing commas should be wrapped in quotes

Example CSV:

name,age,city
John,30,New York
Jane,25,Los Angeles

Converted to JSON:

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