Would you like to just drop a file (like a PDF) into your Google Sheets™ spreadsheets? With the DropSpread sidebar, you can drop it from anywhere and it will automatically upload the file to your Google Drive™, and place the correct link in your spreadsheet. You can even set it up to automatically rename your file, so you can find it more easily later. DropSpread keeps track of the files you uploaded in case you make a mistake.
