About CSV to JSON Converter

Turn CSV rows into JSON arrays or objects without uploading the data.

Input is processed locally in your browser and is not sent to Navorika.

How the calculation works

Standards-aware parsing

A stateful parser handles quoted delimiters, doubled quote escapes and line endings instead of splitting on commas.

Optional type inference

Recognizable numbers and booleans become JSON primitives, while empty values become null.

How to use this tool

1Paste CSV text.
2Choose the delimiter and header behavior.
3Review JSON and the table preview.
4Copy or download the JSON file.

Understanding the result

Header mode creates one JSON object per data row.

Without headers, each CSV row becomes a JSON array.

Important limitations

Type inference is deliberately simple and leaves dates and leading-zero identifiers as strings.
Malformed unclosed quotes are reported instead of guessed.
