You can significantly reduce the number of errors in data entry in Excel by protecting changes of specific
spreadsheets (worksheets) and cells.
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
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.
If you are working with huge workbooks that contain a very large number of formulas, functions, and data,

spreadsheet similar to the wallpaper that you may display on your Windows desktop.
Using the Hide command you can hide the data and formulas from "inquisitive minds". But some of them
still can use Unhide command. Nevertheless you can completely hide Excel spreadsheet so that it will
be needed some VBA programming to unhide it.
You can make a worksheet more visually appealing and easier to read by centering text across multiple
columns. Often you do this by merging and centering the merged cells, but it is not the only option.
