I need an addon / extension for google sheets to assign custom or different user rights for each cell or row / column. For eg I have a sheet of stock / inventory with columns - Product name, Quantity, Cost, Sale Price. Suppose I have 20 people on staff. I want to share that sheet with all of them but with different user rights for different people. Senior managers may view & edit all columns while sales managers may see all except Cost column but cannot edit any column except Sale Price. Similarly all other staff may only see Product name & Sale Price and edit none. (see attachment for a screenshot of this file)
I can restrict editing with protect sheet & ranges option but how can I restrict viewing of certain cells ?
Also I want to restrict editing & viewing of many cells & ranges (rows or columns) in whole workbook just by a single click and similarly unlock or un restrict file by a single click for users as specified in row no 7 & 8 of attached screenshot.
After this one I need 1 more addon and troubleshooting for google sheets , docs , etc...
