Use for questions about programmatically interacting with inbuilt protections in any spreadsheet. Use with appropriate spreadsheet software tag like [excel], [google-sheets], [libreoffice-calc], [openoffice-calc] and the language tag like [python], [google-apps-script]. Do NOT use for non-programmatic usage.
Protection is a inbuilt feature in most spreadsheet software, where some parts of the spreadsheet like sheet or range can be protected from unwanted edits from users.
