If you must protect a file, use Excel’s feature, which encrypts the entire file. Avoid using the weaker “Protect Sheet” or “Protect Workbook” options, as these do not encrypt the data. Choose a complex, unique password (e.g., a 16+ character passphrase with upper and lowercase letters, numbers, and symbols) to make any brute-force attempt impractical.
Access Denied.

If you must keep sensitive information in a spreadsheet, use the built-in encryption features (password-protect the Excel file itself). filetype xls inurl passwordxls 2021
This specific query is often used by security researchers—and unfortunately, malicious actors—to find spreadsheets containing sensitive login credentials, account details, or financial data that were uploaded to a web server without proper access controls. Security Best Practices
: If a web server has directory listing enabled, a crawler can view every file stored in a folder. If an administrator uploads a spreadsheet to a public folder, the search engine will index it.

: Competitors or threat actors gain insight into internal structures, financial budgets, and proprietary vendors.
