CSV ↔ JSON Converter

Convert CSV tables to JSON records and back.

How it works

CSV needs unique, non-empty column headings. CSV values remain strings. JSON must be an array of objects with primitive values; nested objects and arrays are rejected. Spreadsheet-safe export is enabled by default to prefix potentially executable formula cells with an apostrophe.
