Abstract
The present disclosure relates to access control and data extraction within multi-tab cloudbased document platforms. Existing platforms enforce file-level permissions in an all-or-nothing manner, granting collaborators access to every tab within a document. Extracting individual tabs requires manual copy-paste operations into separate documents. The disclosed architecture introduces tab-level virtual sandboxing that selectively renders authorized tabs while masking unauthorized tab nodes from a user's viewport and client-side document object model. A tab copyextraction feature parses and clones tab content into a new, editable cloud document while preserving the original tab. An atomic extract-and-purge operation transactionally clones a selected tab to a standalone cloud document and, upon confirmation, deletes the original tab from the master document. These features enable granular sharing, streamlined extraction, and reduced document bloat.
