CSV to JSON

How to use CSV to JSON

1. Paste your text into the input box, or drop a file onto it.
2. Choose your options.
3. Press Convert to JSON.
4. Copy the result or download it in the format you need.

Example

name,age
Ada,36
Grace,45

[
  {
    "name": "Ada",
    "age": 36
  },
  {
    "name": "Grace",
    "age": 45
  }
]

The header row becomes the keys; numbers are detected.

Good for

• Turning spreadsheet exports into API data
• Preparing test fixtures
• Converting reports for JavaScript apps

Leading zeros are safe

Values like 00123 or +44 are kept as text so nothing is lost. Turn off number detection to keep every value as a string.
