DATA CONVERTER

Convert CSV rows into structured JSON locally.

Transform a small comma-separated export into an array of JSON objects. The first row becomes property names and quoted fields are parsed in the browser.

HOW IT WORKS

Header-based CSV conversion with quoted-field support.

Each non-empty data row becomes an object whose keys come from the first row. Quoted commas, doubled quote characters and line breaks inside quoted fields are handled.

Your data stays local

The transformation runs in this browser tab. ClearText Tools does not upload the input to a processing server.

Review the output

Copy the result only after checking structure, edge cases and any values that affect production systems.

Known boundaries

Input must use commas as delimiters
Values remain strings
Duplicate or blank headers are rejected

Common questions

Is my input uploaded?

No. This tool processes the input locally in your browser.

Can I use the result without checking it?

Use it as a fast transformation, then validate important output against the requirements of the destination system.
