What issue are you seeing?

When an Excel file (.xlsx) is opened inside Codex Desktop, the displayed content does not refresh in real time. After the file is modified and savedby an external program (or the file is changed on disk), Codex keeps showing the old/cached version of the spreadsheet instead of the latest content.

What steps can reproduce the bug?

1. Open an .xlsx file in Codex Desktop.
2. Keep the file open in the Codex view.
3. Edit and save the same file using an external application (e.g. Excel,

LibreOffice, or a script that writes to the file).

1. Switch back to Codex Desktop and look at the displayed content.

What is the expected behavior?

Codex should detect that the file on disk has changed and refresh the preview, or at minimum offer a "reload / file changed on disk" prompt so the latest content is shown.

Additional information

This makes it hard to work with spreadsheets that are updated by external tools or scripts, since the displayed data can silently fall out of sync with the actual file on disk.
