How to convert CSV to JSON

With header row

name,age
Ada,36
Linus,54

[
  { "name": "Ada", "age": 36 },
  { "name": "Linus", "age": 54 }
]

Does the first row become the keys?

If you enable the header option, yes. Each column header becomes a key and every following row becomes an object.

Are numbers kept as numbers?

With typing on, values like 42 and true become a number and a boolean instead of strings. Turn it off to keep everything as text.

Does it handle quoted commas?

Yes. Standard CSV quoting is respected, so a value like "Doe, John" stays intact.

Is there an API?

Yes. Every conversion is available via a JSON API with a free tier and pay-as-you-go pricing for higher volume.
