Working with Read-Only Workbooks
When you open a read-only workbook, you’ll notice a few differences in the user interface compared to a regular editable workbook. Here’s what you need to know:
Viewing and Navigating
When a workbook is opened in read-only mode, the spreadsheet application will typically display a message indicating that the file is read-only. You’ll still be able to view and navigate through the workbook as you normally would, but you won’t be able to make any changes to the content.
Formula and Function Evaluation
Read-only workbooks can still evaluate formulas and functions. This means that even though you cannot edit the cells directly, the formulas and functions will continue to work and display the correct results. This is especially useful when you want to share a complex spreadsheet with others who need to see the calculated values without the risk of changing the underlying formulas.
Data Visualization
Read-only workbooks also allow for the visualization of data through charts, graphs, and other visual representations. You can create and view these visualizations just like in a regular workbook. This is a powerful feature when you want to share data insights without allowing modifications to the underlying data or visualizations.
Collaborative Features
While read-only workbooks restrict direct editing, they can still facilitate collaboration in other ways. For example, in Google Sheets, you can add comments to cells, allowing for discussion and feedback without altering the actual data. Additionally, you can use the chat feature to communicate with other viewers of the read-only workbook.
Advanced Techniques for Read-Only Workbooks
Read-only workbooks offer a range of advanced techniques to enhance their functionality and security. Here are some strategies to consider:
Password Protection
