For the web and APIs

Turn CSV into clean JSON.

Each row becomes an object and each header a key. Control column names before downloading readable JSON.

A usable structure

The first row supplies property names, uniqueness is checked and values remain text to avoid unexpected conversions.

Correct before converting

Rename headers, remove columns, search values or delete duplicate rows. Undo remains available before export.

Empty cells and special characters

Quotes, line breaks and Unicode are escaped correctly. Empty cells remain empty strings.
