Frequently asked questions

Can I recover my documents after closing the page?

Documents are saved automatically in this browser and restored when you return. Closing a document with X deletes it. Browser cleanup can also remove saved work; download important results or export your workspace.

How are nested values written to CSV?

Objects and arrays become JSON text in cells. Formula-like cell content is escaped for safer spreadsheet opening.
