What this conversion does
Reading CSV
A CSV, TSV or semicolon-separated export is read to RFC 4180: quoted fields, doubled quotes, and commas or line breaks inside a cell all survive, and the delimiter is detected rather than assumed. The first row becomes the table header, and a cell holding a line break is flattened onto one line — a Markdown table row cannot span lines.
Writing JSON
A structured saveai.doc.v1 tree: a title plus typed blocks for headings, paragraphs, lists, quotes, code and tables — ready to feed a script, a database or another tool, and convertible back into a document here at any time.
