CSV to JSON

FAQ

How are CSV headers mapped?+

The first row becomes property names. Each following row becomes one JSON object in an array (or a single object if there is only one data row).

How are nested fields restored?+

Headers like user.name or items.0 map back to nested objects and arrays using dot-separated paths.

What about quoted fields and commas?+

Standard CSV quoting is supported. Fields with commas or quotes should be wrapped in double quotes in the input.

Does conversion run on a server?+

No. Parsing and JSON output happen entirely in your browser.

What if my CSV has no header row?+

The first row is always treated as headers. Add a header line or prepend column names before converting, or the first data row will become property names.
