When to use this tool

Examples

CSV rows to JSON objects

Input

name,team
Ada,Platform
Lin,Data

Output

[
  { "name": "Ada", "team": "Platform" },
  { "name": "Lin", "team": "Data" }
]

The first row is treated as the object keys.

Quoted values with commas

Input

name,notes
Ada,"Ships APIs, docs, and tools"

Output

[{ "name": "Ada", "notes": "Ships APIs, docs, and tools" }]

Quoted CSV fields can contain commas without becoming separate columns.

Format and behavior notes
