Protection in Excel 2016
Protecting workbook elements
Protecting a workbook is different from protecting the Excel file with a password to prevent reading/writing or locking the spreadsheet elements to prevent editing. Workbook protection forbids other users to add, move, rename or delete worksheets and defends against viewing hidden worksheets or hiding worksheets.
Protect Excel spreadsheet options
To protect your spreadsheet, Excel proposes the following options:
Hide formulas from appearing in the edit bar
Usually, you can view formula in the Excel the cell when cell is selected, but you can protect a spreadsheet to hide formulas in some cells.
Allow specific users to edit ranges in a protected spreadsheet
Excel offers you an ability to assign user-level permissions to different areas on a protected spreadsheet. You can specify which users can edit a particular range while the spreadsheet is protected. As an option, you can require a password to make changes.
Share workbook and track changes
With Excel built-in tools you can easily work together on workbooks and monitor who, when and what changes made. E.g., track project status and tasks.
Protecting spreadsheet elements
Working with large and complex Excel workbooks, especially when entering large amounts of data, no one is protected from accidental changes in formulas, formats, and other spreadsheet elements. But you can protect yourself from too much work on finding and eliminating such errors by protecting the individual spreadsheet elements.
How to protect spreadsheets
You can significantly reduce the number of errors in data entry in Excel by protecting changes of specific spreadsheets (worksheets) and cells.
Locking cells in a spreadsheet
Sometimes you might want to lock cells in your Excel spreadsheet that contain formulas and functions or data. Thus, the person doing the data entry will not accidentally overwrite or delete the spreadsheet formulas and functions or your data.
