We've learned to write protection for Excel cells, so it's just read-protected. Reading protection means that people don't see what we write in Excel cells.

To set the reading of a cell read-protected by setting the color of the cell, the text color is the same as the back color. Or use other images to cover the cells that need to be protected, to cover the original of the cell, for read protection purposes. You can also read protection by setting the cell's row height and column widths, hiding the selected cells, and then protecting the worksheet so that users cannot directly access the cells that are hidden.

The most effective read protection is to encrypt the Excel file and turn it off, so that people who don't know the password can not open the Excel file, and can not talk about reading the data in Excel cells.
