Sheets

Sheet lifecycle, copying between workbooks, visibility, protection, and freezing panes. Terms are in the glossary.

Undoing sheet deletion — one step back

undo_delete_sheet_bounded doesn’t restore just any deleted sheet, only the last one: there’s exactly one slot reserved for it, and it’s freed as soon as the undo is used. There’s no going back two steps.

This undo lives within the current session and only on the .xlsx package path. The wrong path gets the refusal bounded-sheet-undo-delete-route-not-live; nothing to restore gets bounded-sheet-undo-delete-empty.
