Why convert CSV to JSON?

JSON is easier to use in API examples, front-end fixtures, configuration snippets, and import scripts. Converting CSV saves manual editing when table data needs to become structured data.

Are quoted commas and line breaks supported?

Yes. Values wrapped in quotes can contain commas, semicolons, tabs, and line breaks. Escaped quotes are also preserved, which matches the way most spreadsheet tools export CSV.

What happens when rows have different column counts?

The tool keeps converting and shows warnings. Missing cells become empty strings, and extra cells receive generated names so the data is not silently dropped.

Is pasted CSV uploaded?

No. The CSV is parsed in your browser, and the JSON output stays on your device until you copy it. berryfy does not receive or store the data.

Turn table data into structured JSON

CSV is convenient for spreadsheets, exports, and quick reports, but it becomes awkward when you need structured data for a test fixture, documentation example, import script, or support note. This converter turns rows into readable JSON objects or arrays.

The delimiter can be detected automatically, or you can choose comma, semicolon, or tab when the file format is known. Quoted fields, escaped quotes, and line breaks inside quoted cells are handled so common spreadsheet exports keep their intended values.

When a row has fewer or more cells than the header, the conversion still completes and shows a warning. That lets you copy useful output while still noticing data that may need cleanup. Everything runs in the browser and is not uploaded.
