Hide Data so Sheet Doesn't look like worksheet


Can I hide all column characters ? I noticed I can hide row numbers , however, how can I hide row numbers ??

How can I hide the toolb ox of text formatting ?
How can I lock all cells but few ?

I also want to show only specific columns and not unlimited columns, and on the other hand allow to add specific number of rows.

there is no way to control rows/columns numbers (you may change label of column, but not row).
Also there is no way to hide toolbox at all, but you may run readonly mode, it prevents data from changing by users.
