What this conversion does
Reading JSON
JSON written in our own saveai.doc.v1 shape — a title plus an array of typed blocks — is rebuilt into a real document, with headings, paragraphs, lists, quotes, code and tables all restored. Any other JSON is kept intact inside a fenced code block instead of being guessed at, so nothing is invented and nothing is lost.
Writing CSV
A spreadsheet-ready grid with RFC 4180 quoting and a UTF-8 byte-order mark, so Excel opens CJK text as text instead of mojibake. Every table in the document is written out; when there is no table at all, the text goes out as a single column rather than an empty file — and the converter tells you which of the two happened.
How to convert JSON to CSV
Open the converter
Source and target arrive already set to JSON → CSV. There is nothing to configure.
Drop the file, or paste the text
One file at a time. You can also type straight into the editor and watch the preview keep up.
Convert and download
The result shows up in the preview pane first, so you can check it before the .csv file lands in your downloads.
