Worked Examples

Simple table

Input CSV:

name,age,city
Alice,30,London
Bob,25,Paris

Output JSON contains objects with name, age, and city keys for each row.

Quoted fields with commas

Input CSV:

product,description,price
Widget,“Small, round widget”,9.99
Gadget,“Includes ""turbo"" mode”,24.50

The description field contains a comma and escaped quotes — both are handled correctly.

JSON back to CSV

Paste the JSON output back into the right panel and click JSON → CSV to round-trip your data.

Supported CSV Format

This tool follows the RFC 4180 standard. Fields are separated by commas. If a field contains a comma, newline, or double-quote, it must be enclosed in double quotes. A literal double-quote inside a quoted field is escaped as two consecutive double-quotes (""). The first row is always interpreted as column headers.
