[BUG]: Excel copy-paste converts text to PNG image instead of plain text

[morpheus9393]

Describe the bug
When copying text from Microsoft Excel and pasting it into Goose chat the application automatically converts the content into a PNG image instead of preserving it as plain text. This prevents text-based LLM models from understanding the input since they cannot process image content.

To Reproduce
Steps to reproduce the behavior:

1. Open Microsoft Excel
2. Copy any amount of text/data from Excel (happens also when copying just 1 cell)
3. Paste into Goose chat interface
4. Observe that the content is converted to a PNG image instead of plain text

Expected behavior
Text copied from Excel should be pasted as plain text into Goose chat, maintaining the original text format without any image conversion.

Actual behavior

• Text copied from Excel is automatically convert to PNG image
• Text-based LLM models cannot process the image content

Screenshots

Desktop (please complete the following information):

• OS: Windows 10, 64bit
• Goose Version: 1.15.0
• Excel Version: Excel Professional Plus 2021

Additional context

• Workaround suggested: convert Excel to CSV first, then copy or copy text to editor before and then to Goose
• Alternative workaround: use MCP servers (Google Drive or Excel MCP) to let Goose read directly from the sheet

Proposed Solution
Add a "Paste as plain text" option or keyboard shortcut to override automatic image conversion when pasting from external applications like Excel.
