In-depth explanation

Convert CSV to JSON (with or without a header row) or turn a JSON array of objects back into CSV. Everything runs locally in your browser — your inputs are not uploaded to produce the result.

Fields wrapped in double quotes can contain commas. Escaped quotes use the standard "" form. A non-empty array of objects (keys become headers) or an array of arrays.

Turn off “First row is header” to convert CSV into a JSON array of arrays. Tweak the inputs above to compare options, then copy or note the result you need.
