This will serve as a guide on how to create a COCO file using the utility script for Google Drive and DropBox

You can find the utility script for Google Drive here: generate_coco_from_drive.js

• You must have a Google account

  • Click on "New Project"
  • Rename the project name to your-project-name
• Paste the utility script
  • Replace the default code with the utility file's code
• Replace placeholder values
  • Replace your_coco_export.json with your output filename
  • Replace your_public_folder_id with the ID of your Google Drive folder

The folder ID is the alphanumeric string that appears after "/folders/" in the URL.
Eg: drive.google.com/drive/folders/1prcCevijN5mubTllB2kr5ki1gjh_IO4u?usp=sharing
