Disclo-sheet is a Bash script that, given a list of URLs, filters XLS and XLSX files, downloads them, takes a screenshot, and creates an index.html file. This allows you to quickly visualize each screenshot at a glance and understand its content. It speeds up the process of searching for sensitive information in XLS(X) files.

1. Give execution permissions to the script:

chmod +x disclo-sheet.sh

2. Run the script with a list of URLs:

./disclo-sheet.sh urls_list.txt

3. The script will create a folder containing:

• The downloaded XLS/XLSX files.
• Screenshots of each file.
• An index.html file for easy visualization.

1. wget for downloading files.
2. libreoffice or soffice for rendering XLS/XLSX files.
3. convert for taking screenshots.
