What’s New in Excel2Mail

This release focuses on reliability, formatting accuracy, and real-world Excel workflows.

✅ Excel formatting preserved

Borders, background colors, fonts, and alignment from Excel tables are now retained when pasting into emails.

Excel’s internal styles are converted into email-safe inline formatting for better compatibility with Gmail, Outlook, and Yahoo Mail.

✅ Plain-text fallback (new)

If Excel does not provide rich HTML (for example in RDP, Citrix, CSV files, or restricted environments), Excel2Mail automatically pastes a clean, structured table instead of failing.

Ensures something always pastes when the toolbar button or shortcut is used.

✅ One-click paste (no extra UI)

Click the toolbar icon to paste immediately at the cursor position.

No popups, dialogs, or additional buttons.

Keyboard shortcut Ctrl + Q continues to work as before.

✅ Improved stability

Uses a proven insertion method directly in the compose window.

Eliminates silent failures seen in earlier versions.

Tested with Thunderbird 115 ESR, 128, and newer builds.

✅ Welcome screen on install / update

A brief welcome screen explains how to use the add-on after installation or update.

ℹ️ Known limitations

Due to email client restrictions:

Conditional formatting and gradients may not be preserved.

Column auto-width may differ slightly between email clients.
