Question details

The user is trying to copy cell data from Excel and paste it into the Mac Messages app, but the data pastes as a file attachment instead of plain, readable text.

How to Stop Excel from Pasting as a File in Mac Messages

Product: Microsoft Excel, Apple Messages
Device & OS: macOS
Scenario: Sharing spreadsheet data via instant message by copying cells from Excel and pasting them directly into an iMessage conversation.
Observed behavior: The pasted content appears as a file attachment rather than plain text, preventing the recipient from easily reading the text directly in the chat. This happens across various Mac and Excel versions.

Before you start

Before proceeding, try pasting the copied Excel data into a basic text editor like Notes or TextEdit to verify whether the text itself is being successfully copied to your Mac's clipboard.

Solution 1Recommended

Use a Plain Text Editor as an Intermediary

Since this is a known interaction bug between Excel's complex clipboard formatting and Apple Messages, routing the text through a plain text app strips the problematic file data.

Microsoft Excel copies data to the clipboard in multiple formats, including HTML, Rich Text, and Object Links. Apple Messages often misinterprets this complex data package as an attachment file.

By pasting the data into an app that only accepts plain text, you can strip away the hidden file formatting before moving it to Messages.

Copy the cells from Excel

Highlight the desired cells in your Microsoft Excel spreadsheet and press Command + C to copy them.

Open TextEdit or your browser's address bar

Launch the native TextEdit app on your Mac, or simply click into the address bar of your web browser (like Safari or Chrome).

Paste and recopy the text

Paste the copied cells (Command + V) into the plain text area. The data will appear as raw text. Highlight this plain text and copy it again (Command + C).

Paste into Mac Messages

Open the Mac Messages app, click the text input field for your conversation, and press Command + V. It will now paste as normal text.

Use a Plain Text Editor as an Intermediary

Quick Alternative: Spotlight Search (Command + Space) also works as an excellent temporary plain text field for this trick.

Solution 2

Use 'Paste and Match Style' in Messages

macOS includes a built-in shortcut designed to strip rich formatting when pasting into native apps.

Solution 3

Escalate to Apple and Microsoft Support

If workarounds are too tedious for your daily workflow, submitting formal tickets to Apple and Microsoft helps prioritize a permanent patch for this interaction bug.

Frequently Asked Questions

Why does Excel paste as a file instead of text in Mac Messages?

This happens due to how Microsoft Excel packages data on the macOS clipboard. Excel includes complex formats like Object Links and Rich Text alongside plain text. The Apple Messages app sometimes gets confused by this payload and defaults to attaching the data as a file rather than extracting the text.

Can I force Excel for Mac to copy only plain text?

No, Excel inherently copies multiple data formats to the clipboard simultaneously to ensure compatibility across different Microsoft Office applications. You cannot force it to copy only plain text, which is why pasting into a plain text editor first is often required.

Does this issue affect other messaging apps on Mac?

Generally, no. This specific bug is primarily observed when pasting directly from Excel into Apple's native Messages (iMessage) app. Third-party communication apps like Slack, Microsoft Teams, or WhatsApp usually parse the clipboard text correctly.
