Welcome!
Please find below links to the official Add-ons I have developed and that are available in the Google Workspace Marketplace:
Bulk convert Google Drive files quickly and easily with this Add-on. Convert between Google, Microsoft Office, PDF, etc. Point the Add-on at a Google Drive folder, select the file types you want to convert, select your destination folder and whether you want the original file to be deleted, then hit go!
Bulk Rename Files Add-on
Bulk rename Google Drive™ files/folders quickly and easily with this Add-on. You define exactly what you want to search for in the file/folder name and the text to replace it with. Along with options for handling special characters, regular expressions and append/prepend to the existing file/folder name. Works across My/Shared drives.
Easily move/archive a row of data from one Google Sheet (tab) to another, within the same file. If you prefer something a bit quicker than cut/paste and with less chance of human-error. It will also remember your individual preferences for each file so it is even quicker to use next time around.
