I added one boolean column to one of my app’s sheets and I don’t know what happened (i made a column ‘row owner’) it ‘deactivated’ the entire sheet, it’s still there but it’s darkened out and the parts of the app that use it don’t work, are invisible. Please help ---

Ok, an accidental click made a column with row owner but now many rows (seems like the ones that were false in the boolean I added) HAVE BEEN DELETED, how do i undo all the damn steps that have been done in the database so far?? ---

Have you tried the `back button` in the lower left hand corner? ![image](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/a/d/adfd8c8a48dc65b19315449dab5602ba7b0d7b88.jpeg) ---

I can’t undo anything with that button atm, so, it’s not an option i suppose ---

in google sheets different cells are greyed out, Idk for what reason, and the rows that have been deleted in glide are the ones that were false in the boolean i added, except 2 (4 actually), or so it seems ---

You’re right, the back button is only available in the builder, not the data editor. Sorry about that. Easy to say in hindsight, but it’s a good practice to duplicate your apps in the dashboard to have a backup. Also, when I make changes both in the data editor and in the builder and I know I might mess up, I usually at the very minimum duplicate the tab. I don’t know how to duplicate Glide tables, but I’ll practice on test columns first. ---

Thank you for trying, I closed the browser’s tab and reopened it and everything seems fine. I’m trying to think to a failsafe, probably duplicating the app every now and then but Imake so many small changes that it would be too much, there should be some undo function, for now I know that google sheets has an history function, so in case I was ready to use that backup plan. Thanks again ---

One thing I’ve noticed sometimes is that when you make changes to Row Owners (add/remove a row owner setting, for example), the web browser needs to be reloaded for everything to work properly and update. ---

Here is some simple app script for backup with a timestamp from @Jeff_Hager. > [@Backup My Data In My Spreadsheet](https://community.glideapps.com/t/backup-my-data-in-my-spreadsheet/1147/2): > > First of all, google does keep a history of any changes. You can access them by clicking the link at the top of the sheet: I also use this script to backup my sheet every week. The only thing that needs to change in the script is the destination folder. This gives me a weekly backup with a timestamp attached to the name: // Abhijeet Chopra // 26 February 2016 // Google Apps Script to make copies of Google Sheet in specified destination folder function makeCopy() { // generates… Simple. Powerful. Effective ---
