If there are no connections listed in the "Workbook Connections" window and you are still seeing a green border around the Excel file, there might be other reasons for this visual indicator. Here are a few additional possibilities and steps you can take:

1. Excel Tables:
• Check if there are any Excel Tables (ListObjects) in the workbook. Excel Tables can sometimes be mistaken for external data connections.
• To check for tables, go to any cell within your data range, and if it's part of a table, you should see the "Table Tools" tabs in the ribbon.
2. Linked Data from External Sources:
• Check if there are any linked data or external references in your workbook. This could include formulas linked to data in other workbooks or worksheets.
3. Conditional Formatting or Data Validation:
• Review any conditional formatting or data validation rules applied to the workbook. Sometimes, these features can create visual indicators.
4. Workbook Views:
• Check if there are any custom workbook views applied. Views can store settings related to the display of the workbook.
5. Review Named Ranges:
• Look at any named ranges in the workbook. Named ranges might reference external data.
6. Hidden Worksheets or Objects:
• Check if there are hidden worksheets or objects in the workbook that might be contributing to the issue.
7. Check for Macros or VBA Code:
• If the workbook contains macros or VBA code, review the code to see if it includes any external references or formatting instructions.
8. Try Opening in Safe Mode:
• Open Excel in safe mode and see if the green border persists. Safe mode disables add-ins and other customizations that might be contributing to the issue.

If after reviewing these aspects, you still cannot identify the source of the green border, it might be a good idea to create a copy of the workbook (as a backup) and then gradually remove elements (such as tables, named ranges, etc.) to narrow down the cause.

In order to provide more help, more information is required, such as Excel version, operating system (Win., Mac, etc.), storage medium (Sharepoint, OneDrive, etc.), file extension (.xlsx, xlsm, etc.). Additionally and if possible, the file (without sensitive data) would be of great advantage.
