title: Protect range to allow editing of **values only** (ie. protect all formatting)
body: <p>I'm thinking this is not possible with the current version of Google Sheets, but thought I'd ask anyhow:</p>
  
  <p>I want users to be able to enter values in a specific range within a spreadsheet, but I want to prevent them from altering the formatting (in particular the data validation and conditional formatting).  I'd also like to prevent them from adding new rows/columns or from deleting rows/columns.</p>
  
  <p>Is this possible?</p>
