With FileDrop you can add files to your Google Sheets™ cells by simply dragging files in the sidebar or click it to browse your computer. It will automatically add the name of the file in cells and create the link to the file in your Drive.

You can upload in bulk or just one file, it supports any type of file, PDF, XLSX, DOCX, ZIP or images. The files are automatically added to your Drive in the FileDrop folder. It keeps a file history so you can add files later on or you can even add files you already uploaded in your Googe Drive™.

This simple add-on saves you time and makes adding files as easy as possible.
