HOW TO

How to use CSV to JSON

Prepare tabular data for APIs, applications, and automation.

  1. 1

    Choose a CSV whose first row contains the column names.

  2. 2

    Process the file and check the preview’s keys, row count and values.

  3. 3

    Copy the JSON array or download the .json file for your application.

INPUT AND OUTPUT

Use the header row as JSON field names

Each CSV data row becomes a JSON object. Values remain strings: an identifier such as 001 stays "001", and a quoted cell such as "Tea, green" remains one value instead of being split at its comma.

This tool does not infer numbers, booleans or nested objects. Use unique, nonempty column names and review malformed rows before importing the result into an application.

FAQ

Common questions

Are my files uploaded?+

No. This tool processes files in browser memory on your device.

Is the tool free?+

Yes. Core processing is free, requires no account, and adds no watermark.

Are numbers and identifiers converted to JSON numbers?+

No. CSV values remain strings, preserving identifiers such as 001. Convert field types deliberately in your destination application if needed.

How should commas inside a CSV value be written?+

Use valid CSV quoting, for example "Tea, green". The parser treats that quoted comma as part of one cell.
