JSON output

Good to know

The first row is treated as the header. Extra cells beyond the header are ignored; short rows are filled with empty strings. Everything runs in your browser.

Example: CSV → JSON

Input

Ada,36
Alan,41

Output

[
  {
    "name": "Ada",
    "age": "36"
  },
  {
    "name": "Alan",
    "age": "41"
  }
]

Frequently asked questions

Does the first row have to be a header?

Yes, the first row is used as the JSON object keys. Empty header cells become column_1, column_2, and so on.

Are quoted fields with commas supported?

Yes. Standard CSV quoting is fully supported: "New York, NY" stays one field, and doubled quotes ("") become a literal quote.

Is there a file size limit?

No hard limit. Processing is local, so it depends only on your browser's memory.
